In Table 5 , each vertical column represents a group of characteristics specific to medication A, B, and C, while each row illustrates the levels of a particular attribute in each of the medication scenarios. The participants are asked to select their preferred scenario and therefore, they have to trade-off attributes and levels against each other.
In CA methods, regression techniques are used to estimate the relative importance of the attributes and the utilities (part-worths) of the levels [ 19 , 23 ]. Moreover, the maximum amount of money that the patients are willing to pay for service or treatment is known as the willingness to pay (WTP) [ 44 , 58 ]. The part-worths are interval data within each attribute that represent the utilities of the levels within that attribute. Generally, part-worths are scaled to an arbitrary additive, while the relative importance is percentages data that are given to each attribute. The higher the percentage the more important is that attribute to the respondents and the relative importance of all attributes add up to 100%.
Several traditional quantitative and qualitative methods have been used to study patients’ preferences. However, these studies were limited in number [ 59 ]. These methods have been used to accentuate patients’ preference in general but did not identify the trade-off that patients make to one of the treatment factors against another [ 60 ]. Unlike traditional questionnaires, the CA method can be used to study preferences [ 13 ] and quantify the trade-off that patients do between the different treatment factors [ 61 ].
Nowadays, there has been a rapid increase in the use of CA to quantify preferences for various healthcare services and treatment options [ 62 ]. For example, in clinics where the majority of cases are non-urgent, CA was found to be a useful tool for allowing patients to discuss their needs and choose medication, health service, and diagnostic tests that suit them the most [ 63 , 64 ]. In turn, CA constituted a supportive tool for clinicians to better understand patients’ preferences and individualize their treatment plans [ 24 , 65 , 66 ]. Hence, the CA use in practice was suggested as a tool to effectively strengthen the communication between patients and healthcare professionals and to engage both parties in the shared decision-making process [ 12 , 62 ]. A scoping review of the studies using CA recommends the use of CA to identify patient preferences for mental health services, which could improve the quality of care and increase the acceptability and uptake of services among patients [ 67 ].
In the hospital setting, implementation of CA constituted a feasible and useful tool in several clinical areas such as investigating hospital stakeholders’ decision-making in the adoption of evidence-based interventions [ 68 ], eliciting patients preferences regarding diagnostics and screening [ 69 , 70 ], improving decision-making regarding patients’ treatment [ 71 , 72 ], understanding patients’ perceived needs and expectations [ 73 ], and determining the clinical factors that physicians prioritize regarding patients’ treatment [ 74 ]. Furthermore, the CA method was very useful during the recent pandemic, as it has been used to understand how people prioritize when deciding whether to present to the emergency department during the coronavirus disease (COVID-19) pandemic for care unrelated to COVID-19 [ 75 ]. This understanding of patients’ priorities helps healthcare professionals to structure an appropriate patient safety assessment which led to remarkably reduced chances of deaths, departments’ crowdedness, and spread of infections [ 75 ]. Moreover, CA was seen to efficiently assess the cost-effectiveness value of alternatives when patients are requested to select their preferred treatment option taking into consideration their financial situation [ 76 ]. Thus, CA is a practical method for generating treatments’ marketing decisions in the pharmaceutical industry, which highly relies on patients’ preferences about a specific drug.
Throughout the discussed CA-based studies, we can discern that CA is a major asset for valuing patients’ important contributions in the decision-making process by assessing patients’ preferences in accordance with treatment selection, patient care, offered health services, and cost comparisons. Research-based literature verified that CA can be a practical method of estimating utility for any combination of attributes, including combinations representing goods or services which may not currently be available [ 77 ]. Thus, when studying patients’ preferences for treatment, CA allows patients to choose their preferred treatment option based on the treatments’ characteristics in isolation of treatments’ names or market brands. Therefore, the precise performance of CA can offer valuable approximation in relation to the relative importance of different aspects of care, the trade-offs between these aspects, as well as the total satisfaction or utility that respondents obtain from healthcare services [ 19 ].
Recently, it has been suggested that the value of CA is not only related to its elevated frequency of implementation but also to the unique ability of this method to generate individuals’ preferences realistically enough to match various decision-making processes faced by individuals in the real world [ 78 ]. Assessing the validity of CA means examining the ability of this data collection tool to accurately measure what it is supposed to measure [ 79 , 80 ]. There are many types of validity and some of these types may overlap, and researchers may argue the names of different types of validity; for example, face validity is often confused with content validity [ 81 ]. Over 20 years ago, very little was known whether CA works in predicting significant real-world actions [ 82 ]. However, within the last couple of decades, researchers have been studying and investigating the validity of CA. Despite the high expansion of CA usage in market and healthcare research, CA validity studies are still limited. A large validity study including over 2000 commercial CA research indicated that there was no validity gain for CA over time [ 83 ]. This could be due to the variation in the CA tools, the expansion of recruitment methods to online and social media, and the differences in the estimation parameters used for each study. In general, the validity for all CA tools can be measured in two ways:
Generally, as the use of CA in the healthcare setting increased, some validity studies were performed to approach more patients’ preferences and expectations. These were not focused only on the patients’ benefit–risk trade-offs, but also on evaluating the patients’ WTP for treatments or services [ 55 ].
Over the years, CA design enabled researchers to elicit and quantify patients’ preferences for treatments and services using a smaller number of scenarios extracted from a larger pool of choices [ 1 , 19 , 72 , 87 , 88 , 89 ]. CA is well known for providing easy experimentation for aspects such as price and features before launching a new product, treatment, or health service [ 90 ]. It is suggested that when people are deciding between multi-attributes alternatives, they apply an unconscious scoring mechanism or system of their preference weight; CA is capable of uncovering this system [ 18 ]. This is achieved by providing respondents with the opportunity to make trade-offs between the specific features of competing items to reach final realistic decisions [ 18 , 91 ]. These trade-offs are based on the value that people place on each attribute.
Some of the limitations of the CA methods are due to the lack of validated quality assessment tools for CA studies and lack of consensus on appropriate sample sizes [ 1 , 3 , 4 ]. Furthermore, one of the inherent limitations of CA is that respondents are evaluating hypothetical scenarios, which might be different from what they do in real life [ 59 ]. It is suggested that the CA questionnaire fatigues respondents as it takes more time to complete than traditional questionnaires and it requires more focus and concentration [ 92 ]. It is also suggested that many patients are not well exposed to research surveys [ 57 , 93 ]. Therefore, reconsidering the number of questions and alternatives presented to participants during data collection is vital to avoid unnecessary respondents’ fatigue [ 1 , 4 ].
To the best of our knowledge, this is the first article to report the trend of CA publications and citations over the past 70 years and the increase in its popularity based on the amount of published literature. This article takes a well-defined, rich, and clear approach to the discussion of CA. It provides a summary of the very large and wealthy literature describing CA methods. The narrative nature of this article is based on a comprehensive search of the literature and utilized several databases. However, the narrative nature of the discussion could be subjective and open to different interpretations. Therefore, we recommend that the results of this article must be interpreted in line with its limitations. The results in relation to the CA trend over the past 70 years are not based on a comprehensive bibliometric analysis in terms of visualization. Nonetheless, it is based on a comprehensive search of WoSCC databases to identify the growth in CA publications.
The popularity of CA in healthcare has been increasing and its use in this setting is gradually competing with its use in business and marketing research. CA is a useful method for eliciting patients’ preferences and WTP. However, there are some limitations in the available CA literature, specifically regarding the appropriate sample size, quality assessment tool, and the validity of CA. This highlights the need for researchers from different fields that use CA methods to come together and develop tools to address these limitations.

Conjoint Analysis is a sophisticated statistical technique used in market research to decipher how consumers value different attributes of a product or service. By presenting respondents with a series of choices that include various combinations of product features, Conjoint Analysis helps identify the most influential attributes that drive consumer preferences and purchasing decisions. This method can be considered a more specialised form of Key Drivers Analysis , which identifies the most impactful factors influencing outcomes, and Latent Class Analysis , which uncovers hidden subgroups within a dataset.
This method breaks down consumer preferences by asking them to evaluate different product configurations or product features. For example, consumers might be presented with various combinations of features for a new smartphone, such as battery life, camera quality, and price. By analysing these choices, businesses can uncover the relative importance of each attribute and understand which combinations are most appealing to different consumer groups. This process of tailoring the model to different groups is akin to the segmentation techniques used in Segmentation Analysis , where consumer groups are categorised based on shared characteristics.
Conjoint Analysis is invaluable in product development and pricing strategy. It provides actionable insights into which features should be prioritised and how much consumers are willing to pay for them. This ensures that new products are designed to meet consumer needs and are priced appropriately to maximise market acceptance and profitability. For instance, if the analysis reveals that customers place a high value on battery life over camera quality, a smartphone manufacturer might focus on enhancing battery performance in their next model.
In real-world applications, Conjoint Analysis has been used by companies across various industries to optimise their offerings. For example, in the automotive industry, manufacturers use it to balance features like fuel efficiency, safety, and design. In the tech industry, companies leverage it to fine-tune features and pricing of hardware and software. This method helps businesses stay competitive by aligning their products more closely with consumer desires.
Conjoint Analysis has a rich history that traces back to the early 1970s when it was introduced as a method to better understand consumer preferences and decision-making processes. The technique was developed by marketing researchers Paul Green and Vithala Rao, who sought to create a more sophisticated approach to market research than traditional survey methods.
Initially, Conjoint Analysis was used primarily in academic settings to study consumer behaviour and preferences. However, its practical applications quickly became apparent, and it soon gained traction in various industries. The early methods involved presenting respondents with a set of hypothetical products and asking them to rank or rate their preferences. These responses were then analysed to determine the relative importance of different attributes.
Over the years, advancements in computer technology and statistical methods have significantly enhanced the complexity and capabilities of Conjoint Analysis. Modern techniques allow for more detailed and accurate analyses, including the ability to handle larger datasets and more attributes. Software advancements have also made it easier to design and administer Conjoint Analysis surveys, broadening its accessibility and application. Techniques from Survey Weighting are often incorporated into Conjoint Analysis to correct biases in the data and ensure accuracy. These techniques also facilitate specialised conjoint methods, such as the constant sum patient allocation exercise, where choice exercises are framed in terms of, for example, the percentage of patients prescribed a treatment.
The evolution of Conjoint Analysis has led to the development of various methodologies, including Discrete Choice-Based Conjoint (CBC), MaxDiff, and Best-Worst Scaling , each offering unique advantages for specific research needs. These advancements have solidified Conjoint Analysis as a vital tool in marketing research, product development, and pricing strategy, helping businesses make data-driven decisions that align with consumer preferences.
Although Conjoint Analysis is the popular term for this family of techniques it is also referred to in academic circles and literature as Discrete Choice Modelling.
At The Stats People, we specialise in several types of Conjoint Analysis, each designed to address specific research needs and provide actionable insights. Here’s an overview of our preferred methodologies and a critique of some common alternatives.
Choice-Based Conjoint Analysis (CBCA) which we sometimes refer to in the Stats People as full Discrete Choice Modelling (DCM) is a widely used method that presents respondents with a series of choice tasks . Each task includes a set of fully described product profiles, and respondents are asked to choose their preferred option. This approach closely mimics real-world purchasing decisions, providing robust data on consumer preferences and trade-offs. Choice-Based Conjoint Analysis is particularly effective in scenarios where predicting market or preference shares for the full product is more important than understanding the relative hierarchy of which attributes are driving the choice. The method’s realism and flexibility make it ideal for diverse applications, from product design to pricing strategy.
MaxDiff, or Maximum Difference Scaling, is a simple but powerful trade-off technique . It asks respondents to identify the most and least important alternatives from sets of simple options. These options can be product benefits, standalone
Single-level features (sometimes referred to as simple attributes), or any other set of stimulus options we want to trade off. This scale free method is highly effective for determining the relative importance of each option. MaxDiff is particularly useful in product development and feature prioritisation.
Best-Worst Case 2 (BWC2) is a half-way house between a full-DCM Choice Based Conjoint Analysis and a MaxDiff . Just like in a simplest trade-off model, respondents are presented with multiple sets of features and are asked to choose the best and worst in each set, however, unlike MaxDiff, BWC2 allows a full attribute grid, just like CBC would, with attributes and levels. We usually deploy BWC2 when the main goal is to understand what attributes and attribute levels are driving the choice, rather than to estimate product share. Unlike a CBC it allows the attributes’ utilities for all attributes and levels to be estimated and compared on a single scale. This method provides a deeper understanding of consumer decision-making processes and helps refine product features to align more closely with market demands.
While other methods like Adaptive Choice-Based Conjoint (ACBC), Menu-Based Conjoint (MBC), and Adaptive Conjoint Analysis (ACA) are popular, we prefer our tailored methodologies. ACBC and ACA, for instance, adapt the survey based on previous responses, which can introduce complexity and respondent fatigue and requires the use of specialist survey hosting software which isn’t a requirement for CBC, MaxDiff and BWC2.
MBC allows respondents to select combinations of features from a menu, which can be useful but often complicates the analysis due to the vast number of possible combinations. We find that our chosen methods provide clearer, more actionable insights without the added complexity.
Conjoint Analysis offers several key benefits that can significantly enhance business strategy, product development, and market positioning. Here’s how:
Conjoint Analysis provides deep insights into consumer preferences by breaking down how customers value different product attributes. This understanding helps businesses tailor their offerings to better meet customer needs and desires. For example, a company can determine whether specific groups of consumers prioritise price, performance, or specific features, enabling them to design products that resonate more effectively with that group. This insight is also crucial in Segmentation Analysis , as understanding consumer preferences helps in categorising and targeting specific market segments.
By revealing what attributes consumers value most, Conjoint Analysis helps businesses understand their competitive position . Companies can compare their offerings against competitors’ and identify areas where they have a competitive edge or need improvement. This insight allows for strategic adjustments that can enhance market share and overall competitiveness.
Conjoint Analysis is instrumental in determining the optimal pricing strategy for a product . By understanding the trade-offs consumers are willing to make, businesses can set prices that reflect the perceived value of different features. This leads to better pricing decisions that maximise revenue without sacrificing customer satisfaction.
The detailed data obtained from Conjoint Analysis in marketing research can inform broader market research efforts. It helps in segmenting the market based on preferences, allowing for more targeted marketing strategies. These insights can guide advertising campaigns, product launches, and other marketing activities to ensure they are aligned with consumer expectations and behaviours.
Insights from Conjoint Analysis guide product development by highlighting which features are most important to consumers . This allows businesses to focus their innovation efforts on areas that will deliver the most value. By prioritising features that consumers care about, companies can create products that are more likely to succeed in the market.
Conjoint Analysis supports data-driven decision-making by providing clear, quantifiable insights into consumer preferences. This helps businesses make informed choices about product features, pricing, and market positioning, reducing the risk of costly mistakes and increasing the likelihood of success.
By aligning products and services with consumer preferences, businesses can significantly enhance customer satisfaction. When customers feel that a product meets their needs and preferences, they are more likely to be satisfied and loyal, leading to repeat business and positive word-of-mouth.
Conjoint Analysis has been effectively employed by The Stats People to help various clients enhance their product development and pricing strategies. Here are two notable case studies that illustrate its successful application and provide a conjoint analysis example:
The Stats People were engaged by a leading medical research agency to perform a complex Choice Modelling study on trade-offs between branded and biosimilar ophthalmology products across multiple countries. This study required customised approaches for each market, incorporating various attributes like discounts and existing prescribing practices.
Project Execution:
The project began with detailed planning to define the requirements for each hypothetical scenario and product. The Stats People then developed a customised simulator integrating all parameters and included a dashboard interface. This required extensive data handling and iterative adjustments to meet client specifications.
Challenges:
The key challenge was adapting to ongoing client requests that did not fit the conventional Choice Modelling framework. The team had to find practical solutions to incorporate these new requirements into the existing model.
The final deliverable was a highly customised Excel-based simulator with a dashboard add-in, successfully meeting all the client’s objectives and providing a powerful tool for analysing market trade-offs.
The Stats People were enlisted by a company to analyse employee preferences for various remuneration and benefits packages using the Best-Worst Case 2 (BWC2) method. This approach was chosen to understand which elements of compensation were most valued by employees and how the company could optimise its offerings to enhance satisfaction and retention.
The project started with identifying key attributes of the remuneration and benefits packages, such as salary increments, bonuses, health insurance, and flexible working hours. The BWC2 method was then employed to present these attributes in sets, asking employees to select the most and least preferred options in each set. This approach allowed The Stats People to gather detailed insights into the relative importance of each benefit component.
A significant challenge was ensuring that the BWC2 model accurately reflected the diverse preferences of the employee base. The team had to manage and interpret a large volume of complex data, requiring careful calibration of the model to ensure that it provided clear and actionable insights.
The analysis resulted in a highly detailed understanding of employee preferences. Flexible working hours and health insurance emerged as top priorities, while bonuses and salary increments were less critical. These findings enabled the company to restructure its benefits package to align more closely with employee values, leading to increased job satisfaction and reduced turnover.
These case studies highlight how conjoint analysis can provide valuable insights that drive strategic decisions, leading to enhanced customer satisfaction, better product development, and optimised conjoint analysis pricing strategies.

Sometimes, commercials really get me.
T-Mobile 's Super Bowl commercial this year is a prime example — "What's for Dinner?" demonstrates the infuriating process of choosing what to do for dinner for a young couple, and it's gold .
The reason T-Mobile's ad was so relatable is because of their market research. They looked at what their target audiences wanted — including their thought processes, what informs their decisions, and the trade-offs they're willing to make for their products.
To accomplish all of these important factors in one go, many companies use conjoint analysis.
Conjoint analysis is a market research tactic that attempts to understand how people make decisions. A common approach, the conjoint analysis combines realistic hypothetical situations to measure buying decisions and consumer preferences.
Think about buying a new phone. Attributes you might consider are color, size, and model. The reason phone companies include these specs in their marketing is due to research such as conjoint analysis.
Would consumers purchase this product or service if brought to market? That's the question conjoint analysis strives to answer. It's a quantitative measure in marketing research, meaning it measures numbers rather than open-ended questions. Questions on the phone company survey would include price points, color preference, and camera quality.
Surveys intended for conjoint analysis are formatted to reflect the buyer's journey.
For instance, notice in this example for televisions, the specs are the options and the consumer picks what best reflects their lifestyle:
This direct method of giving consumers multiple profiles to then analyze is how conjoint analysis got its name. These answers are helpful when determining how to market a new product.
If answers on the phone company survey proved that their target audience of adults ages 18-25 wanted a green phone from $400-600 and a camera with portrait mode, advertisements can cater directly to that.
The conjoint analysis shows what consumers are willing to give up in order to get what they need. For instance, some might be willing to pay a little more money for a larger model of a phone if their preference is larger text.
Choice-based conjoint (CBC) and Adaptive Conjoint Analysis (ACA) are the two main types of conjoint analysis.
Choice-based is the most common form because it asks consumers to mimic their buying habits. ACA is helpful for product design, offering more questions about specs of a product.
Choice-based conjoint analysis questions are usually presented in a "Would you rather?" format. For example, "Would you rather take a ride-share service to a location 10 minutes away for $13 or walk 30 minutes for free?" The marketer for the ride-share service could use answers from this question to think of the upsides to show off in different campaigns.
ACA leans towards a Likert-scale format (most likely to least likely) for its attribute-based questions. Respondents can base their preference on specs by showing how likely they are to buy a product with slight differences — for example, similar cars with different doors and manufacturers.
To create a conjoint analysis, you'll first need to define a list of attributes about your product. Attributes are usually four to five items that describe your product or service. Consider color, size, price, and market-specific attributes, such as lenses if you're selling cameras.
Additionally, try to keep in mind your ideal respondents. Who do you want to answer your survey? A group of adult men? A group of working mothers? Identify your respondent base and ask specific questions catered to that target market.
The next step is to organize your questionnaire depending on the type of conjoint analysis you want to conduct. For instance, to run an adaptive conjoint analysis, you will present questions with a Likert-scale.
You can use a conjoint analysis tool to create and modify your survey. Then, you can distribute your questionnaire through multiple channels, including email, SMS, and social media.

Sawtooth Software offers a great example of conjoint analysis for a phone company:
The analysis puts three different phone services next to each other. The horizontal column of the model identifies which service is offering a certain program, described by the vertical values. The bottom row shows a percent value of consumers' preferences.
QuestionPro offers this fun, interactive conjoint analysis template about retirement home options. The survey gives you a scenario and asks your course of action. For instance, it asks if you would sign a rental agreement for retirement home housing immediately, and considers specs like rent, meals, size, etc.
Conjoint analysis isn't limited to existing products. They're also very helpful for figuring out if a brand-new product is worth developing. For instance, if surveys show that audiences would be into the idea of an app that chooses clothes for consumers, that could be a new venture for clothing companies in the future.

Conjoint analysis is a marketing research method that leverages statistical analyses and mathematical models to quantify survey respondents' preferences for product features, determine what attributes impact product demand, and can also predict how the market will respond to new products pre-launch.
These research methods use specialized surveys to ask respondents to pick between bundles, and the importance of specific product features is then analytically derived from the results. Once the survey results are collected, the organization can determine how valuable each product feature is and if they should implement them before launch.
For example, a TV manufacturer might conduct a survey where they give the respondents bundles with different features to pick from. Each bundle might include screen type, size, brand, and price. Respondents will choose which bundles are more appealing to them, and the TV manufacturer can determine how much each respondent values certain features.
Conjoint analysis is becoming increasingly popular among market researchers and other organizations because it provides valuable insights that are difficult to obtain elsewhere.
Conjoint analysis helps organizations optimize features and pricing by giving them the means to quantify and study consumer preferences. Using conjoint analysis, organizations can measure the importance of different factors by having customers choose between realistic product packages. Organizations can deduce the importance of various factors, such as pricing and product features, by modeling utilities after the data derived from conjoint exercises. When using conjoint analysis in tandem with market segmentation , you can easily narrow down which customers prefer what features or services.
If you ask consumers directly what is important to them, the answer is usually everything.
For example, most respondents will say that price is very important when buying a smartphone. However, high-price brands like Apple have a very strong market share. Factually, price is less important than product features like the brand, the features, etc. Optimizing features and pricing requires more accurate quantification of consumer preferences. Respondents are not asked to state the importance of different factors. Instead, they are asked to pick between realistic options (products with features and pric es). The importance is derived from the choices they made. This is why conjoint analysis is often used over other methods.
For market research agencies, purchasing survey software is an important decision. For example, many agencies evaluate survey software on three dimensions: functionality, price per complete, and quality of service. Conducting a conjoint analysis across these three dimensions provides insight into tradeoffs between the three.

Effective conjoint analysis models feature natural relationships between respondents and product attributes. Conjoint exercises should appear “au naturel” to customers to yield the most accurate data possible. One way to accomplish this is to tailor conjoint models specifically for critical customer segments; various segments will weigh attributes differently, and taking a one-size-fits-all approach may invalidate the data.
The best conjoint analysis models incorporate natural relationships between respondents and product attributes. Effective conjoint analysis models feature surveys that closely resemble the final decision point; for example, if you conduct a conjoint analysis for phone plans, you might want to replicate a large phone carrier’s bundle price range.
If imperfectly contextualized, the presentation might not reveal natural attribute preferences. Over time, attention to detail on the look and feel has decreased for practical reasons; organizations run more conjoints, and directional results are often enough. However, the best conjoint results leverage UI elements close to the final product to obtain more detailed results.
Where applicable, organizations should tailor conjoint exercises for critical customer segments. For example, an airline may create different conjoint models for frequent and infrequent flyers. Regular airline customers may receive a free, first-class upgrade, so measuring first-class against economy will have to incorporate more factors than just pricing preferences.
For many organizations, it can be challenging to analyze these complexities and adapt their exercises to provide options for critical customers, but it is crucial for gaining valuable insights across all customer segments.
Roughly half of the online survey traffic is mobile, meaning voluminous choice options will not properly fit on a smartphone or similar device’s single screen. In these exercises, scrolling can become too intense for respondents to focus on and cause them to disengage.
It is possible to limit conjoint exercises to desktop users, but this creates a selection bias in survey responses. In many cases, acquiring data from younger respondents becomes challenging. Conjoint presentations have been streamlined, often with intro pages to give details to keep the task manageable on a mobile device.
It is critical for organizations to review and test conjoint exercises on an online device before launching to ensure proper data quality.
There are four different types of conjoint analysis methods that organizations employ during market research: choice-based conjoint (CBC) analysis, adaptive choice-based (ACB) conjoint analysis, adaptive conjoint analysis (ACA), and menu-based conjoint (MBC) analysis.
Choice-based conjoint (CBC) analysis is one of the most common forms of this research method. CBC records how a respondent values different combinations of features within a product or service.
This conjoint analysis method asks survey respondents to review a set of product concepts with potential features and allows them to select their favorite combination. Using these results, researchers can predict the market share for different scenarios, depending on the product they roll out.
Adaptive choice-based (ACB) conjoint analysis models are newer and more advanced than other conjoint models. Adaptive models are most effective when the attribute list grows because it delves deeper into the respondents' preferences. In return, this conjoint analysis method provides a thoroughly engaging experience for the respondent. ACB conjoint analysis models are more detailed and require more time to conduct than a CBC study.
Adaptive conjoint analysis (ACA) is a conjoint analysis research method from the 1980s that provides each respondent with a personalized experience. This conjoint analysis method gives each respondent a different survey experience based on their answers to previous questions. Although many organizations do not use ACA today, it is helpful where organizations must evaluate numerous product features or attributes simultaneously to hasten the process.
Menu-based conjoint (MBC) analysis models are advanced tools that assist in analyzing menu choice experiments with multiple checks. While this conjoint analysis model provides organizations with better opportunities for modeling complex consumer preferences, it requires a high level of expertise. Many organizations will defer this to experienced professionals with the necessary platforms to make this conjoint model scalable and viable.
Conjoint analysis methods help organizations conduct market simulations, predict demand, and estimate price sensitivities for potential products. Many researchers also leverage data from conjoint analyses to organize respondents based on what product attributes and features they prefer. In short, conjoint analysis is used to help companies determine which features users value the most and assists them primarily in the three following areas: pricing, marketing efforts, and research and development.
Conjoint analysis helps businesses determine pricing for different products and services. Using conjoint analysis research methods, organizations can compare various product features to determine how consumers value each. For example, attributes that users appreciate more in service might wind up in a more expensive subscription package, while lesser-valued features might become part of a trial version.
Conjoint analysis methods help organizations create marketing strategies by informing them of which factors are most valuable to various target audiences. Organizations can leverage respondents’ answers about which features are highly favored to determine where they should allocate their marketing resources. Conjoint analysis can also help marketers segment and target different audiences based on what features different demographics value the most.
Insights obtained from conjoint analyses can assist an organization in researching and developing new products and services. For example, if a competitor's product offers more features, they can deploy a survey to their users with sample packages that include those features. If users favor one sample over the others, the organization can move forward with implementing those features.
Modeling is a critical part of running a conjoint project and has evolved over the years. Conjoint experts back in the day were much more attentive to the design and presentation of the choice scenes themselves. We regularly heard concerns about whether respondents would be able to interact with the scenarios in an intuitive way. If imperfectly contextualized, the presentation might not reveal natural attribute preferences. Thus, IntelliSurvey often undertook great efforts to model conjoints that would appear “au naturel” for respondents - in market freezer doors, new car stickers, six-packs, and more.
As conjoint has gotten more "packaged", one can see much more "plug and chug" thinking about the exercises. Presumably, for many exercises, this is just fine. When the “au naturel” target interaction involves respondents picking one plan from three presented in three columns. Such exercises are quite straightforward for data collectors to deploy, sometimes requiring just a few hours.
We're always jazzed to see more complex models, and presentation schematics. We're excited to work with friends old and new from the high-end modeling community, and introduce interested parties to new modeling methods. The world of bespoke still exists, and may be better than the cookbook at reliably modeling the utilities and relationships critical to your business success.
IntelliSurvey has a variety of products to help companies conduct surveys and multi-market studies. IntelliSurvey has been deploying conjoint analyses for more than 20 years and excels at creating models that are intuitive and organic to survey respondents.

Conjoint analysis explained + survey template.
Definition: Conjoint analysis is a research technique used to quantify how people value the individual features of a product or service. A conjoint survey question shows respondents a set of concepts, asking them to choose or rank the most appealing ones. When the results are displayed, each feature is scored, giving you actionable data. This data can help determine optimal product features, price sensitivity, and even market share.
Why Is It Important? Conjoint analysis goes beyond a standard rating question. It forces respondents to pick what product concepts they like best, helping identify what your audience truly values.
Here is an example of Conjoint analysis: A store wanting to release a new ice cream offering needs to determine the optimal flavor, size, and price. Each flavor would become a level for the flavor attribute, while each price point would become a level for the price attribute. Customers would pick from various combinations of these levels, helping identify preferences.
This sample question has five total attributes, displayed over three sets, with three attributes shown per set.
If we offered a new menu item for ice cream, which of the following options would be most appealing to you? Please make one choice per set. If no options look appealing, choose "None."
Option #2 Select | - Select | |||||

This is an interactive example of choice based conjoint
Without conjoint analysis it would be impossible to ask about product prices along with flavor and size; a separate rating question for each flavor and size combination is needed. Conjoint analysis solves these problems with a straightforward survey question. When respondents evaluate this question, concept features are compared against one another, and a researcher can identify preferences.
Conjoint analysis is useful in two specific scenarios, marketing research and pricing analysis.
Conjoint analysis is used in marketing research to identify what features of a product or service are most appealing to a customer base. This research can be conducted on existing products to improve advertising engagement or identify areas of improvement to increase sales. Conjoint analysis could also be used to conduct preliminary research for product feasibility.
A conjoint study will usually include demographic questions such as gender. A marketing executive can then segment the survey data by gender, revealing hidden insights used to bolster marketing strategy.
Conjoint analysis is useful in pricing research because it forces customers to decide using trade-offs, helping to identify optimal prices for various levels. The ice cream example we use in this document has a $5 USD price with the highest utility, which is paired with a "medium" size. Without a conjoint study, it would have been logical to assume the "large" size should be sold for $5. Because of the trade-offs, the optimal size and price combination was found.
If the restaurant chain used multiple rating questions instead of conjoint, respondents would likely rate multiple flavors as good, and likely choose the lowest price. Using that method, it would be hard to gather reliable data.
Often, preliminary data needs to be collected before running your conjoint study. An initial survey would include a MaxDiff or a Van Westendorp question to determine important product features or an acceptable price range. The preliminary survey acts as a baseline to reduce the number of conjoint concepts. A smaller number of concepts reduces survey fatigue and increases the quality of responses.
You also want to organize any custom data that you can be used in the survey. Suppose you want to segment your research by country (USA vs European customers). In that case, you need to make sure that internal data is valid, complete, and accessible by your team before running the conjoint study. If custom data is unavailable, you can add additional questions to the survey before the conjoint question.
With the preliminary survey data in hand and custom data organized, you can now create your conjoint analysis study. You can upload the product attributes and levels, include custom data, and you can add follow-up questions to ensure a successful project.
Conjoint analysis is an advanced research technique that uses a variety of unique terminology. To help you get a complete understanding, here is a list of commonly used conjoint terminology:
The high-level product features that respondents will evaluate are called attributes. Attributes are the first column in the above example question. That example has the following features: flavor, size, and price. If you studied a new car offering, you might have features such as color, make, model, MPG, and tire type. There is a limit of 20 attributes on the SurveyKing platform.
The items listed within an attribute are called levels. In the example, the "Flavor" attribute has levels of "Chocolate," "Vanilla," "Cookie Dough," and "Strawberry." When you create the conjoint survey, you define an attribute and the levels that go with each attribute. There is a limit of 15 levels on the SurveyKing platform.
Combining all your attributes and levels, which creates a hypothetical product, is called a concept. In the above example, concepts are the columns that respondents choose. Concepts are sometimes referred to as "cards" in statistical software. There is a limit of 7 concepts on the SurveyKing platform.
Also referred to as a task, a set contains multiple concepts or product offerings. Respondents will choose one concept per set and then be shown a new set of concepts. There is a limit of 20 sets on the SurveyKing platform.
This term is the most crucial in conjoint analysis. It defines how a respondent values each attribute level. When all the utilities for all respondents are analyzed, a researcher can determine an overall product value. Utilities are the output of a regression equation.
Utilities have no scale compared to other conjoint projects you run. They only matter in the context of the current question you are looking at.
Sometimes utilities are called "part-worths" or "part-worth utilities." We use the term "utility."
Choice-based conjoint.
This is the most common form of conjoint. The example question above is a choice-based conjoint question. Respondents pick the most appealing concept for each set. Each set contains a random set of concepts that are evenly distributed. This type of conjoint best simulates buyer behavior since each set contains hypothetical products (concepts). When respondents choose a complete profile, a researcher can calculate preferences from the tradeoffs made. (e.g even though "Strawberry" isn't a preferred flavor, if the price were low enough, it would still provide consumer utility")
As with most conjoint studies, preliminary research is essential to reduce the number of attributes and levels to choose from. With fewer attributes and levels, the number of concepts is reduced, which lowers survey fatigue. A MaxDiff or ranking survey can be used to find the top four ice cream flavors.
Currently this is the only type of conjoint offered by SurveyKing.
Sometimes referred to as MaxDiff conjoint. Similar to choice-based conjoint, this method shows respondents a set of concepts. In each set, respondents are asked to pick the most/least (or best/worst) concepts. This approach is used when a product or service has features that cause both positive and negative reactions. An example could be studying how parents select daycare. The number of full-time faculty would draw a positive reaction. The percentage of fellow students that are economically disadvantaged could produce a negative reaction.
This is a future addition to the SurveyKing platform.
This method is also similar to choice-based conjoint. Respondents pick the most appealing concept for each set, except with this method, the next set of concepts are not random but are tailored based on the previous answers. This method is more engaging to respondents and can help fine-tune the data.
This method displays many concepts and asks respondents to rate each one based on the likelihood of purchase. This method is outdated and was primarily used prior to the introduction of survey tools that offer choice-based conjoint. Asking to rate lots of concepts at once is error-prone, quickly causes fatigue, and yields low-quality data.
Ranking and rating conjoint was the method used for full-profile conjoint analysis. As software has progressed, it is now possible to conduct rating or ranking conjoint similar to a choice-based conjoint. Respondents are shown a set of concepts and asked to rank or rate each concept. They could rank by entering a value for each concept, which sums to 100 for each set, or they could enter a number based on a scale. This method is also sometimes referred to as "Continuous Sum Conjoint".
Ranking conjoint is a future addition to the SurveyKing platform.
Menu-based conjoint is a new conjoint method. This method gives respondents the ability to pick multiple levels from a menu. For example, a car manufacturer could ask respondents to choose a base model and price, just like choice-based conjoint. But then they could also ask to check a box for each additional feature desired such as "Alloy Wheels for $1,500", "Sunroof for $1,000", or "Parking Assist for $1,500".
This method is much more advanced in terms of front-end programming and back-end statistics than choice-based conjoint. Often custom solutions need to be built for a company wishing to create this type of project.
Any survey that contains a conjoint question is referred to as a conjoint survey. SurveyKing currently only offers choice-based conjoint. Here are the steps needed to create your own conjoint survey:
An ideal conjoint question will have roughly 5 attributes (rows), 4 concepts per set (columns), and approximately 5 - 10 sets. This will help ensure respondents are not fatigued. A detailed breakdown is below:
We recommend collecting at least 100 responses for each segment being researched. For example, if you wanted to research both males and females, you would want to collect 100 responses for both.
Conjoint analysis uses regression to calculate how different attributes and levels are valued.
Because conjoint uses categorical data (a name like ice cream flavor) instead of continuous data (a number like a temperature), a particular type of regression is used called logistic regression . Just like any regression equation, the result of this regression calculates coefficients. These coefficients are referred to as "utilities".
Utility is not a standard unit of measure. It can be thought of as "happiness". If a lot of respondents choose concepts containing "Cookie Dough" and only a few choose concepts with "Vanilla.", even without doing the math, you can imagine that the coefficient for "Cookie Dough" would be higher than the coefficient for "Vanilla."
Let's say the coefficient for "Cookie Dough" is 5 and the coefficient for "Vanilla" is 1. We could interpret this as saying "A Cookie dough flavor of ice cream will add 5 units of happiness to a consumer, while vanilla would add only 1 unit of happiness." We would also factor in the utilities for serving size, and price, to come up with the product (or list of products) that would provide customers with the most value or "happiness".
To illustrate this concept, we ran the above ice cream example with 20 respondents. Below is the analysis of those responses. This analysis includes the utilities for each level in addition to the relative importance of each attribute.
Attribute | Importance | Level | Utility | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Flavor | 61% |
Walking Through the AnalysisThe utilities in the last column are the output of regression analysis. Next to each number is a small bar chart for visual representation. Remember, utilities are not an actual unit of measurement and could be thought of as happiness. If we look at the above table, the "Cookie Dough" flavor has a utility of 14, and the "Vanilla" flavor has a utility value of 7. We could interpret this as "Cookie Dough has double the happiness of Vanilla." The importance column is the weighted difference in utilities ranges for the product levels. You can see that flavor has the level with the largest difference of roughly 7. The larger the utility differences for an attribute, the more important they are to consumers. To get a significant difference, as we see with cookie dough, many respondents choose concepts with that flavor. We know the other levels are evenly distributed, meaning that cookie dough was a significant driving factor in decision-making regardless of size or price. Here's how you would calculate the importance: Take the largest number for each level, and sum: 14.11+4.03+5.06 = 23.02 Divide each of the highest levels by this number. The calculation for flavor importance is 14.11 / 23.02 = 61% Statistical DetailsSurveyKing uses ChoiceModelR , a package in the R statistical program to compute conjoint utilities. ChoiceModelR calculates a coefficient using logistic regression with the maximum likelihood for each attribute level by each respondent. When the analysis is complete, utilities for each level are averaged. The output of our example can be found in this Excel file . We color-coded the Excel file for each attribute level. Row 22 has an average subtotal, which the average utility for a specific level. The regression equations use effects coding to ensure each attribute in total sums to 0. Because of this, you will notice the excel file contains negative utilities. We shift each number by a constant to eliminate negatives and put the baseline to 0. The dark blue flavor columns were adjusted by 5.43 before the results being loaded into our dashboard. Having a 0 baseline makes the data easier to interpret. Data used to populate ChoiceModelR:
Time Spent Per SetThe time spent on each conjoint set is also included in the results. This data is useful to eliminate low-quality responses. Responses that answered a set too fast (under 2 seconds) should generally be eliminated from the results. Analyzing Concept ProfilesA powerful benefit of conjoint analysis is quantifying how each concept would fare in the market. We can easily see the product with the most utility would be Cookie Dough, Medium, for $5 USD. But what about the top three products? Or the bottom three products? In the ice cream example, there were 24 hypothetical products. Unique to the SurveyKing platform is the ability to scroll through each concept in ranked order, to see what profiles faired the best or worst (or offer the most utility). The reporting section will automatically include the table shown below:
To get these figures from the Excel output file, you could create a table with all possible combinations, and use sumproduct to calculate to total utility. Here is an example . Conjoint Analysis by Question SegmentsSometimes it's important to analyze different segments, such as gender. To do this, add a multiple-choice question to your survey for each segment you wish to study. In the reporting section, you can choose "Conjoint Segment Report." From here, select the appropriate question, and the report will output a data table for each answer. Using the ice cream example, you may notice "Males" prefer "Cookie Dough," while "Females" prefer "Vanilla." These are additional data points to fine-tune your marketing efforts. Here is an interactive example of a conjoint comparison report unique to the SurveyKing platform. The first question asks for gender and the second question asks for a preferred ice cream concept. You can see males prefer "Cookie dough" with a utility of 23.06, while females prefer "Vanilla" with a utility of 25.63. Each gender segment lists flavor as the most important attribute. The report also includes a segmented ranking of concepts. Analyzing Concept Market Sharedfsgyfg dfgfsgsfg Sample Survey DataConjoint analysis tips.

What Is A Conjoint AnalysisA conjoint analysis is a market research approach that helps you understand how people make decisions. With conjoint analyses, you see how people make trade-offs in real time, giving you much needed intel on what features to emphasize, and which ones to deprioritize. In essence, it replicates the real-time decisions individuals make during any purchase decision. Customers are faced with many products or services in any given category. And, each of these likely comes with different features, benefits, and price points. By understanding how customers prioritize these elements, you can develop options that increase their purchase likelihood. Business Questions Answered By Performing A Conjoint AnalysisHow do you know if a conjoint analysis is right for you? When talking to prospective clients, we keep our ears open for a few key business questions. These are….
If you find yourself asking these questions, especially when planning for a new product release , chances are a conjoint is worth considering. What You Learn When Performing A Conjoint AnalysisLet’s now breakdown exactly what kind of information you’ll learn when you run a conjoint analysis. For the sake of making things tangible, we’ll pretend we have a financial services company considering launching a new payment product. We need to know how important certain features are to customer preference. Additionally, we want to understand sensitivities to price and feature changes. Preference ImportanceA key learning you’ll get from running a conjoint analysis is something called preference importance. Preference importance lets you see how important individual features are to customers’ purchase decisions. A high importance means that feature has a very strong influence on purchase decisions. In contrast, a low importance means it has very weak influence. In the case of our pretend financial services company, we see that Fee holds a 45% importance preference. This high importance value tells us that customers really care about the product’s fee when deciding whether or not to buy. Meanwhile, Credit Score holds a 5% importance. This tells us that it has some, but very little, impact on our customer purchase decision. In this example, looking at preference importance shows us the the premium customers put on Fees over any other decisions element. Nevertheless, our mocked up data also shows us that we can improve consideration with changes to Payment Period and, to a lesser extent, Rewards. And, it tells us that changing Credit Score won’t have a material impact. Preference ShareAnother learning you’ll get from a conjoint analysis is the preference share within a given feature. Preference share shows how much a given level is preferred over other levels. A high share means that a particular level is very strongly preferred. In contrast, a low share means it not at all preferred. Let’s look at this again in the context of our financial services company. This time, we’re going to home in on the Fees feature. Specifically, we’ll see how much customers prefer paying one fee amount versus others. In this example, customers have a very strong preference for low fees. This is why a fee of .5% has a 65% share while a fee of 1.5% has a 5% share. This outcome isn’t very surprising. Customers always want to pay less. However, when performed for other features (e.g. payment periods), we may see that customers are more balanced in their preferences. Relative UtilityLastly, running a conjoint analysis lets us understand the relative utility of levels within each feature. Said more simply, it lets us identify how sensitive customers are to changes in feature levels. And, it shows when changing certain levels really alienates customers. Once again, let’s look at this for our financial services company. In this example, a .5% fee has a higher relative utility than a 1% fee. However, both of these options have a positive utility. That is, going from .5% to 1% still results in positive customer interest, albeit the fee hike does decrease interest a bit. However, when the fee goes to 1.5%, the story changes. There is now a negative utility. This means we are alienating customers. Relative utility lets us see how elastic or inelastic customers are to feature changes. In the case of Fees, we’re seeing a lot of elasticity. This means that customer demand changes a lot when fees increase or decrease. Meanwhile, customers are less elastic when it comes to Payment Day. We can infer this because the graph shows far narrower shifts in relative utility as payment days change. This represents a valuable insight for businesses looking for ways to improve a product’s economics while increasing customer demand. It tells them which features they can change the most and still keep customer interest high. How To Perform A Conjoint AnalysisWithout getting too deep into the weeds, let’s walk through the standard approach for performing a conjoint analysis. Develop A List Of Features & Feature LevelsFirst things first, you need to determine the specific features you want to test. In the case of our financial services company, this would be things like payment periods, fees, rewards, etc. Then, you need to figure out what levels within those features you want to test. For instance, you may want to look at 10-day, 15-day, and 20-day payment periods. Or 1% versus 2% versus 3% fees. Build A Digital Survey To Capture InputUsing a digital survey tool, we program these different features and feature levels to capture the data needed for subsequent analysis. When taking the survey, respondents see unique product bundles that mix and match different feature levels. For instance, one product may show a 1% fee and a 30-day payment period. Another may show a 3% fee and a 5-day payment period. Respondents select their preferred options. The bundle options then refresh so that respondents see a new set of bundle options. Once again, they select their favorite bundle. This process repeats multiple times across all respondents. Analyze The ResultsOnce the data is in, we can dig into learning the preference importance, preference share, and relative utility of different features and feature levels. Additionally, if sample sizes permit, we also look at findings by unique segments. This tells us if individual customer groups have different preferences and elasticities. Alternatives To A Conjoint AnalysisA conjoint analysis is extremely powerful. But, sometimes it’s overkill. When organizations are in the early days of developing a product or service, you may not even know what features to include. As a result, it’s far too early to dive into testing feature importance, let alone the relative utility of feature levels. Instead, you’re likely better off doing product concept tests . This “dip your toe in the water” approach offers initial validation before you get too entrenched in a product idea. Or, you may have a list of high-level features but aren’t sure which ones truly matter. In this scenario, you’re not ready to test feature levels. You just need to understand the relative value of unique features. If you find yourself in this instance, consider a MaxDiff study instead. This approach gives you clear insight into what features customers really want, and which ones they’re comfortable leaving behind. Most Popular Posts

It involves presenting respondents with a series of hypothetical scenarios and asking them to choose their preferred option. Table of contents What is Conjoint Analysis?What are the types of conjoint analysis.
Benefits of Conjoint AnalysisDrawbacks of conjoint analysis, conjoint analysis examples, tips for using conjoint analysis. Have you ever wondered how companies determine the perfect combination of product features that will appeal to their customers? One popular technique used by market researchers is called “conjoint analysis.” This method involves presenting survey respondents with different product configurations and asking them to rate or rank their preferences. By analyzing the data, researchers can identify which product attributes are most important to consumers and how they interact with one another. In this article, we’ll dive into the definition, types, and examples of conjoint analysis to help you better understand this valuable research tool. Conjoint analysis is a statistical technique used in surveys to understand how people make decisions and evaluate products or services based on their attributes. It involves presenting participants with a series of hypothetical scenarios that vary in the attributes of the product or service being evaluated. By analyzing the choices participants make in these scenarios, researchers can determine the relative importance of different attributes and how they affect overall preference. Conjoint analysis can provide valuable insights into consumer behavior and help businesses make informed decisions about product development, pricing, and marketing. It is commonly used in market research, product design, and customer satisfaction studies.
Why is Conjoint Analysis Important for Researchers?Conjoint analysis is one of the most important tools for researchers as it helps them to gain insights into a consumer’s preferences and decision-making processes on an individual level. It allows for a deeper study of the consumers and attributes involved to create a needs-based segmentation, providing user-based affirmation of what is most valued in the product or service. This helps researchers to understand the trade-offs that consumers make when they evaluate multiple attributes simultaneously, giving them insight into the real and hidden drivers that may not be readily apparent. Furthermore, researchers are able to measure consumer preferences and analyze data to gain statistically relevant insights representative of a larger group. As a result, conjoint analysis has become the gold standard for preference research and is used by many businesses in different industries across the globe. By using surveys, businesses can measure the value that different features have for consumers. This information can be used to create products and services that better meet the needs of customers. By understanding what customers value most, businesses can create offerings that increase satisfaction. Conjoint analysis is a technique that can be used to find the best combination of product features by surveying customers. First, determine the features you would like to examine, and select the target customers to survey. Then, reach out to customers with a survey that presents them with different combinations of features and asks them to rank them based on their preference. After the surveys are returned, analyze the results to determine the optimal feature set for your needs. This analysis can be used to estimate the market share of new products by gathering data from customers on their preferences for different product alternatives and attributes. This data is then used to create a choice model which estimates the likelihood of each product being chosen by potential customers. Conjoint analysis is a tool that can help businesses identify which product features are most valuable to customers. By conducting a conjoint analysis survey, businesses can determine which features are the most important to their customers and develop a marketing strategy that is most successful. Conjoint analysis can be used to evaluate the effectiveness of advertising campaigns by determining what consumers are willing to pay for certain features and attributes. By analyzing the data collected from a conjoint study, marketers can gain a better understanding of what consumers are willing to buy, which allows them to refine their advertising strategies. Conjoints require careful consideration of multiple attributes and levels, which can lead to a complex design. As the number of attributes and levels increases, so does the complexity of the design, making it difficult to manage and analyze. Conjoints often involve asking respondents to evaluate a large number of product profiles, which can lead to respondent fatigue. This can result in lower response rates and lower-quality data as respondents may not be fully engaged in the survey. The results of conjoint analysis are specific to the attributes and levels included in the design. This means that the results may not be generalizable to other products or markets, limiting the usefulness of the analysis. Conjoints assume that respondents make decisions based on a rational evaluation of the attributes and levels presented to them. However, in reality, decision-making is often more complex, and emotional and psychological factors can also play a role. Here are four examples of how conjoint analysis can be used in real-world scenarios:
In conclusion, conjoint analysis is a powerful tool for understanding consumer behavior and preferences. It provides a systematic way to evaluate and compare different attributes of products or services and their impact on overall preference. There are several types of conjoint analysis, including full-profile, adaptive, and choice-based, each with their own strengths and weaknesses. Examples of applications include new product development, pricing research, and customer satisfaction studies. By using conjoint analysis, businesses can gain insights into what factors drive consumer decision-making, and use that knowledge to make informed decisions about product development, pricing, and marketing strategies. FAQ on Conjoint AnalysisWhat is conjoint analysis and how does it work. Conjoint analysis is a market research technique used to determine how consumers value different features of a product or service. It works by presenting participants with a series of hypothetical product or service profiles that vary in terms of their attributes (such as price, quality, and design), and asking them to choose their preferred option from each set. What are the advantages of using conjoint analysis in market research?Conjoint analysis can provide valuable insights into how consumers make decisions and what factors influence their choices. It can also help businesses understand how to price their products or services, design new products or services, and target specific consumer segments. How do you design a conjoint analysis study?To design a conjoint analysis study, you need to first identify the attributes that are most relevant to your product or service. You then need to create a set of product or service profiles that vary in terms of these attributes, using a statistical technique called fractional factorial design. Finally, you need to recruit participants and present them with the profiles, asking them to choose their preferred option from each set. What are some limitations of conjoint analysis?Conjoint analysis relies on participants' ability to accurately evaluate and compare different product or service profiles. If the profiles are too complex or if participants are not familiar with the attributes being tested, the results may not be reliable. Additionally, conjoint analysis assumes that participants make decisions based solely on the attributes presented, which may not be true in real-world situations. Related pagesLogistic regression.

When to use conjoint analysis
How to create a conjoint analysis survey, with example questionsHow does conjoint analysis help interpret preferences .
How does conjoint analysis work?Conjoint analysis is a technique where respondents are presented with a set of product or service concepts and asked to choose their preferred one. Within each description are multiple features (attributes) of that product/service, and options that can be compared on a like-for-like basis. For example, if you were researching toothpaste you might present some of the following options for 100ml tubes with different price points, flavors, and benefit claims:
Respondents are asked to make trade-offs between multiple products. However, the number of attributes included within each product description should be limited - ideally no more than six or seven - so that decision-making isn’t too complicated for the respondent; especially because in a real-life shopping scenario, consumers generally would not compare any more than this number of attributes when making a purchase decision. Back to Table of Contents Conjoint analysis is invaluable for any research into the impact of different product features on consumers’ purchase intent. If asked directly, in either quantitative or qualitative research, consumers will often say that all attributes are equally important, or won’t be able to say exactly which are more motivating than others in their purchase decision. A conjoint’s market simulation approach forces respondents to make trade-offs in the same way they might when making real-world decisions. Even if consumers are unaware of which attributes sway their decision, a conjoint analysis will reveal them. Some common business questions that can be answered with conjoint include:
The consumer preferences extracted from conjoint can be fed into sales, marketing, and advertising strategies in any business. Product design, product development, product management, branding issues, package design, pricing research , and market segmentation exercises all benefit from conjoint analysis. Back to Table of Contents Different types of conjoint analysesAll conjoint studies compare total ‘packages’ of different products/services (the unique combination of attributes that each has), as well as the variations on those different attributes (called ‘attribute levels’ - for example within the attribute of ‘flavor’, the levels might include spearmint, fresh mint, and cool mint). How each attribute and level affect a respondent’s choice is calculated into a numerical value called a preference score (also known as a utility score). This can then be used to model ideal product scenarios, combining motivating attributes with optimum price points to see how they would affect projected market share and/or revenue. Within this method there are different types of conjoint analyses; three examples are given below. 1. Choice-based conjoint analysisAlso known as discrete choice conjoint analysis, CBC is the most-used form of the method. One of its main benefits is that it reflects a realistic scenario of choosing between products rather than questioning respondents directly about the importance of each attribute. Respondents are shown sets of 3-5 concepts at a time and asked to choose their favorite, then the importance of each attribute is inferred from their choices. This is a powerful way to understand which features are most important to include in a new product and how to price it. From this information, brands can derive optimal product configurations. 2. Adaptive conjoint analysisAdaptive conjoint analysis is a flexible approach to CBC, adapting as a survey progresses so that the choice sets that each respondent sees depend on the preferences they have expressed up to that point. Tailoring the questions to each individual streamlines the approach to CBC, as it doesn’t waste time showing product concepts that the respondent would not find appealing, thus cutting down the length of the survey. Respondents can also find this type of conjoint experience more engaging when they see the survey is reacting to their personal preferences. 3. Self-explicated conjoint analysisThis version of conjoint analysis takes the focus off the package of attributes as a whole and instead zooms in on the attributes and attribute levels. Respondents are able to eliminate attributes they wouldn’t consider at all, as well as choose their favorite and least favorite attribute levels. The remaining levels are then rated against the most/least favorite level. The importance of the favorite attribute in the context of the product as a whole is calculated, and a utility score is given for each attribute and attribute level. This CBC method doesn't demand the same level of statistical analysis as other types of conjoints, but it isn’t best suited to pricing research as price can’t be fairly compared to other attributes. In product researchSuppose a fast food chain wants to introduce a new burger to its menu. Some of its business questions before launching this new menu item might be around ingredients, calorie content, taste, and price. The new burger has a number of potential options that it could offer to the market but the fast food business needs to be sure that the options it chooses will have optimal uptake among their diners. Using conjoint analysis, the fast food chain could test the following combinations of product features to respondents, asking them to identify their preferred burger: Option 1: Plant-based, spicy, 650 calories, $5.25 Option 2: Prime beef, spicy, 790 calories, $4.29 Option 3: Prime beef, with cheese, 820 calories, $4.99 Option 4: Plant-based, with cheese, 900 calories, $6.19 Rather than asking respondents about ingredients, taste, calories, and price separately, conjoint analysis presents the features within a realistic product context and analyzes the results to reveal which features are the most powerful in driving purchase. In service researchSimilarly, service propositions can be presented with a variety of feature combinations for respondents to choose from. For example, a TV & broadband service set of options might look like this: Option 1: Fast broadband, basic TV bundle plus sports channels, $50 per month Option 2: Superfast broadband, basic TV bundle, and no sports channels, $90 per month Option 3: Superfast broadband, TV with movies and sports channels, $120 per month Option 4. Fast broadband, TV with movies but no sports channels, $100 per month Conjoint analysis will reveal which parts of the service respondents attach the most importance to and which they will pay more for. Back to Table of Contents Consumers are faced with product decisions every day and there's a lot of different aspects that go into choosing a certain product over another - but often, we don't know what those are. Many standard usage and attitude questions don't quite get into the nitty-gritty details of consumer decision making that businesses need to succeed. Conjoint analysis (a type of advanced methodology) helps researchers unravel consumers' complex decision-making by effectively breaking down product offerings into attributes and levels. By breaking down the overwhelming amount of products (and their features) into distinct attributes, businesses can hone in on what specific features of a product actually impact final decision making. Researchers can present respondents with different attributes in various combinations to understand the overall preference (and therefore, value) of each individual feature. Through conjoint analysis, researchers can quantify trade-offs consumers are willing to make between different attributes, providing insights into their underlying preferences. Knowing this, a business is then in a position to use the most preferred features during the final product design phase, to develop a solid pricing strategy, to craft an influential marketing campaign, and ultimately, to enjoy a successful final product launch. Alternatives to conjoint analysisAs mentioned above, the alternative to using a conjoint analysis for understanding decision making might be left to standard usage and attitude questions such as 'Which product do you prefer' or 'How much do you like this product'?; a s you might guess, these outputs aren't going to give you nearly the same actionable insights as a conjoint analysis will. While conjoint analysis is one of the best methodologies a brand can use to understand feature importance, there are some alternatives for those who don't have access to conjoint or who prefer to go another route: MaxDiff (Maximum Difference Scaling):MaxDiff is similar to conjoint analysis in that it forces respondents to make tradeoffs, but the difference is that it focuses on the most and least preferred features individually, rather than evaluating the features as part of set combinations (which is more realistic to a true shoppers' experience). Van Westendorp Price Sensitivity Meter (PSM):For brands looking to make a decision around pricing specifically, Van Westendorp is a great method to use to understand how price sensitive your consumers are. Respondents are asked a series of questions to determine acceptable price ranges for a given product (i.e at which price point the product is considered too cheap, too expensive, a bargain, or justified). The intersection of all these price ranges helps identify an optimal price range. But remember, pricing is just one aspect that a brand could test in a conjoint analysis, creating a much more cohesive understanding of a product rather than looking at price alone. Key Driver Analysis (KDA):The end goal for researchers running a conjoint analysis is really to learn what's driving consumer purchases. Another advanced methodology that's effective in uncovering this kind of information is, as it's aptly named, the Key Driver Analysis (KDA). A KDA identifies the overall factors or variables that have a significant impact on a particular outcome - such as product purchase intent in this case. This is a useful method when looking to understand the overall impact a variable might have on consumers' decisions, while a c onjoint analysis is better at understanding and optimizing individual features.

August 06, 2024 Conjoint Analysis: a comprehensive practical guideAppinio Research · 20.10.2022 · 13min read Product development and market establishment pose significant challenges for many companies. During the development process, the central questions are: What features do customers expect, and which ones are the most important? Unfortunately, approximately 95% of new product launches fail because they do not meet customers' requirements, expectations, or needs. Therefore, it's crucial to conduct research to answer these questions and avoid potential failures. Fortunately, these questions can be answered during the development phase with the help of a conjoint analysis. In this article we'll explore how you can leverage the power of the conjoint analysis enabling the prediction of potential consumers' behavior in advance by presenting realistic purchase scenarios to identify gaps in existing product competition. What is the conjoint analysis?The term conjoint comes from a combination of "considered" and "jointly," which also defines the conjoint analysis. It involves considering various product features (attributes) together and weighing them against other variants. The Conjoint analysis originated in psychology and was developed by Robert Luce and John Tukey in 1964. Since then, it has primarily been used in market research and product development to determine what attributes consumers want and perceive as particularly important during the development stage. Attributes can include functions, designs, or features such as weight, size, and price. However, because consumers tend to want as many attributes as possible for the lowest cost, conjoint analysis takes a different approach from methods such as the MaxDiff Method . The distinctive feature of the conjoint method is the combination of different attributes instead of independent comparison. This makes it useful for high-priced products like automobiles, hardware such as laptops or smartphones, luxury goods, as well as everyday products or during the conception phase. The concept of the analysis is simple. Consumers are shown different products that differ in the combination of features. This creates a realistic experience that closely mimics an everyday purchase decision. For example, in a conjoint analysis to determine consumer preferences for types of chocolate, the filling attribute might be divided into levels such as vanilla cream, strawberries & cream, and kiwi ganache. In this sample conjoint analysis, the aim is to determine which types of chocolate consumers prefer and what price they are willing to pay for each type. The respective attributes are leveled, i.e. they are displayed in a certain form. For the chocolate example the filling attribute is divided into the levels vanilla cream, strawberries & cream and, kiwi ganache. Using this approach, a ranking can be created that shows which attributes are most important and which characteristics are most attractive. This evaluation can then be used to decide on the most appealing and profitable combination for both consumers and the company. What is the difference between the conjoint method and Discrete Choice Model?While there are some similarities between the Conjoint analysis and the Discrete Choice Model (DCM), there are also some notable differences. Both models are preference-structured and designed to uncover the factors that influence consumption choices . However, the key difference lies in how respondents view the product profiles and their attributes. In a Conjoint analysis , respondents view the product profiles in smaller groups, while in a DCM , they see all the products simultaneously. This makes the DCM a bit more realistic in predicting buyer behavior than the Conjoint analysis. However, it can also be overwhelming for respondents as they are presented with a large number of options. One of the advantages of the Conjoint analysis is that it provides more information about the attributes' relativity and importance to each other, as well as their contribution to the final buying decision. This is not possible with the DCM. Moreover, the Conjoint analysis is an excellent tool for predicting behavior before the product is launched, which is less likely when using a DCM. The Choice-Based conjoint methodThe Choice-Based conjoint analysis (CBC) is the most popular form of conjoint analysis and for good reason. Unlike other forms, CBC analysis asks consumers to make decisions between product variants and accept trade-offs , resulting in a more detailed and realistic analysis. This approach reflects the fact that we make numerous decisions daily where we weigh different attributes against each other. In CBC analysis, all previously defined attributes are combined evenly to create a statistically valid ranking at the end of the analysis. Although there are other types of conjoint analysis, such as the Adaptive Choice conjoint and the Menu-Based conjoint analysis, they are not as flexible as the CBC method and cannot be used as widely. At Appinio, we specialize in CBC analysis and can help you gain valuable insights into consumer preferences and behavior. Use cases for Conjoint AnalysisThe conjoint analysis is a versatile market research method suitable for a variety of use cases. Three common applications of conjoint analysis are: Concept testing Conjoint analysis is useful for testing product concepts in the early stages of development. By identifying consumer preferences and potential flaws early on, resources can be saved and the risk of a failed product launch can be minimized. Diversification and product range expansion The conjoint method is also helpful for testing new product variants, such as different sizes, flavors, or colors, and for optimizing the product range. Price determination The conjoint analysis can be used to determine the optimal price for a product or service. It can be used as a stand-alone method or in combination with other price analysis techniques like Van Westendorp price analysis . By testing different concepts for their willingness to pay, businesses can make informed pricing decisions. Research experts answer: When exactly should a Conjoint Analysis be conducted?

Learn how to use conjoint analysis for market research and content strategy. When you’re developing a marketing strategy, one of the first and most important steps is to do your research. In order to actually sell your product or service, you need to fully understand your target audience when they’re in an actual buying situation:
One of the most effective ways to answer each of these questions is with conjoint analysis. Defining conjoint analysisConjoint analysis is a survey-based statistical analysis technique used during market research that quantifies the value customers place on attributes of a product or service. Already that may sound complicated, so let’s break it down a little more. Conjoint analysis is a statistical technique that uses a survey to determine consumer preferences before they make purchase decisions. It asks each respondent a series of questions—also known as choice tasks—in which they select between a few packaged options based on relative importance and what they deem most valuable. Each package presents different product features, called attributes, and each attribute shows multiple types, or levels. Here are some examples of attributes:
Next, here are examples of each attribute level:
As they answer each question, respondents determine which trade-off feels like the best deal for them. Finally, companies use the data from that survey to determine a utility score, revealing which attribute(s) respondents find most valuable. Survey data can also be used to measure the consumers’ overall preference scores, which state a consumer's likelihood to purchase a packaged option based on preference. Types of conjoint analysisThe reason why this method is called conjoint analysis is because survey respondents have to choose a conjoined product package with different attributes and levels. When developing a conjoint analysis survey, companies can use a variety of statistical techniques. Each method asks the respondent a different series of questions that businesses can leverage for different insights. Choice-based conjoint analysis (aka discrete choice conjoint analysis)This is the most prevalent type of conjoint analysis that market researchers use. Choice-based conjoint analysis (CBC)—or discrete choice conjoint analysis—simulates the market and demonstrates how respondents value certain attribute levels. Since this method is also most commonly used to explain how conjoint analysis works, let’s go over an example. Say you’ve started a car cleaning service and you want to develop a survey that asks customers what sort of cleaning package they’d prefer. You break down your service into attributes and levels. The attributes could be price, services provided, time spent cleaning, and a manual vs automated car wash. Then you include different levels of pricing, services, and time. Once your survey is complete and you analyze your conjoint data, you may learn that more respondents would prefer a car service that’s quick and inexpensive. Or you may learn that respondents would rather spend the extra $10 for a wax and tire polish—despite the service taking much longer. Adaptive conjoint analysis (ACA)Adaptive conjoint analysis (ACA) is similar to CBC analysis. The difference though, is that each question updates in real time and adapts to each respondent's choices. Adaptive conjoint analysis is ideal for when respondents need to evaluate more attributes than in a choice-based survey. This way, companies can get a full perspective of what their customers value and are looking for by presenting combinations of attributes and levels that companies may not have thought of before. ACA is also a more efficient way of surveying respondents because each follow-up question becomes more curated to each input answer, which makes the survey feel more relevant and pertinent to the respondent’s values and desires. Full-profile conjoint analysisThis conjoint analysis technique requires a full description of each product in a choice task. Other market research techniques usually limit the number of attributes, but with full-profile conjoint analysis, the respondent is able to see a thorough description with every attribute. Respondents then select which product they’d purchase with maximum likelihood. Menu-based conjoint analysisTypically, a conjoint survey doesn’t ask respondents outright what they’d like to pay for a product or what features they’d like to see with it. Menu-based conjoint analysis surveys differ because they enable the respondent to package a product by themselves. This allows companies to see how potential customers may value certain combinations of attributes and levels. Of course, everyone would like to have the best-quality product that’s inexpensive, comes with all sorts of benefits and features, or takes the least amount of time to finish or arrive. However, menu-based conjoint analysis surveys prompt respondents to categorize each predetermined attribute and level so they can customize a packaged product that they feel would deliver the most value. Why use conjoint analysis for market research?Companies often conduct conjoint analysis surveys because they are one of the best survey methods for determining customer values and preferences during the buying process. Let’s go over the business benefits of conjoint analysis and why it’s so effective. Highlight consumer preferencesWhen companies know which product features are the most valuable to consumers, they can highlight them in their advertisements. Say, for example, you learn that one respondent group values your brand’s environmental mission and another group values the quality of your materials. With data from your conjoint study, you can target some consumers with ads that highlight your stance on climate change while other ads target consumers that are looking for a brand with high-quality materials. Companies can also use a conjoint analysis experiment to determine which new product features to add or take away based on survey data, utility scores, and preference scores. If you learn that most respondents preferred an old feature compared to a potential new one, you could save time, money, and resources that would be spent launching new products with multiple features that your customers wouldn’t prefer as much. Mimic real-life trade-offsPeople make trade-offs every day. However, not all trade-offs are created equal because different people have different priorities. For example, some people trade sleeping in so they can go to the gym and grab breakfast to go before starting work; others may prefer to sleep in more and prepare a quick breakfast at home before work. Conjoint analysis mimics this kind of daily trade-off. For instance, when it comes to purchase decisions, consumers often trade:
As mentioned, conjoint analysis doesn’t necessarily ask respondents what they specifically prefer in a product or service. Instead, it demonstrates a realistic context by asking respondents to choose which packaged option they prefer, ultimately revealing which attribute level respondents are willing to trade for another. Develop insightful product and pricing researchConjoint analysis methods allow companies to gain insights on how much a consumer monetarily values their product or service. By developing conjoint surveys that focus primarily on product and pricing research, companies can understand how much consumers are willing to pay. Simulate competitive marketsBusinesses can develop surveys that employ a brand price trade-off approach, wherein they learn if consumers have a bias toward a competitor solely based on a name brand. This allows companies to simulate a competitive market situation, allowing them to see whether or not customers would prefer them over another brand and why. Predict marketing trendsInstead of hoping that a new product, feature, or service will land well with new consumers, conjoint analysis can help companies make more informed decisions with their marketing strategies. Companies often use conjoint analysis to forecast potential demand, predict marketing trends, or determine product acceptance before they launch by noticing trends and quickly acting on relevant data. 5 steps to creating a conjoint analysis surveyLet’s go over the 5 steps to creating an effective marketing research campaign with a conjoint analysis survey. Step 1: Define attributes, levels, and a pricing structureWhen you start developing a conjoint survey, make sure you can succinctly define each attribute and level, and that you have enough to present a few packaged options to a respondent. Break down your product or service into attributes of interest and define each level that you want to evaluate. Take a look back at our choice-based conjoint analysis example for ideas of where to start. Also keep in mind what your price range is so you can position each price level as slightly above and slightly below your range. This ensures that respondents don’t all reply that they’d want a price that’s much lower than you’d like. Note that the only way to move forward from here is if you have succinct, well-defined attributes, levels, and pricing. If these aren’t defined, you likely won’t get a lot of actionable insights. Step 2: Create a conjoint surveyThere are tons of websites that provide conjoint analysis software, and some even allow users to create a survey for free. You can also create a survey on platforms like SurveyMonkey or with any of Mailchimp’s free survey tools . Before you start, think about which conjoint analysis method you’d like to use. Here’s a quick breakdown on how to use each type of conjoint analysis we covered:
Step 3: Invite survey respondentsYou invite survey respondents by sending an email to subscribed customers or potential consumers. Always let your invitees know that their opinion matters and that your survey is for consumer preference research that will help you better understand them. You can even provide a small incentive for participating in your survey, such as a discount or the chance to win a gift. However, before you send out survey invitations, make sure you have reliable resources to collect their response data. Most survey platforms offer ways to manage invitations and collect insights. However, some offer more helpful analysis insights than others, so make sure to choose your survey platform wisely. Step 4: Analyze survey dataOnce the responses to your market research survey are ready, your selected conjoint software or survey tool will analyze the data and provide insights on each utility and preference scores. Each score will outline which product or service respondents are most likely to purchase, which features are most desired, and which attributes have the most impact during the buying process. Step 5: Deploy conjoint data in marketingFinally, you have your data, preference scores, and other valuable analysis insights. However, remember that it’s okay to not get everything you need after one survey. You may need to do a few rounds of surveys for different audiences or at different times. It’s possible you may have to adjust your survey completely if you find that another conjoint analysis technique may be more helpful. Nonetheless, your first survey can help you start implementing your newfound understanding into marketing strategies, campaigns, and advertisements. Also, no matter what you learn, just know that it can take weeks or months to implement your findings into a marketing strategy. Always set realistic expectations and stick to a schedule in order to stay on top of your marketing goals. Understand the consumer with conjoint analysisConjoint analysis is an ideal way for businesses to learn more about trending preferences and pivot upon learning what consumers like or don’t like. Deploying a conjoint analysis study not only enables businesses to effectively provide what consumers are looking for, but it can save businesses time, money, and resources that might get squandered by just guessing what is currently trending. Even if your findings surprise you and your team, a conjoint analysis method can help you strengthen your marketing strategy and get you closer to your customer base—which is really valuable in the long run. What is conjoint analysis? The complete guideConjoint analysis is used to build market models and forecasts to answer questions such as "Should we build in more features, or change our prices?" or "Which of these changes will hurt our competitors most?", or "What is the optimum price to charge?" that allow the business to optimise product and service design to customer needs. To explore or play with conjoint analysis, try our interactive Conjoint Demonstration , our simple conjoint in Excel to see how conjoint analysis works numerically, or use our free, full-featured Conjoint Explorer to design and test your own conjoint experiments. Conjoint overviewEvery customer making choices between products and services is faced with trade-offs ( see our conjoint demonstration ). Is high quality more important than a low price and quick delivery for instance? Or is good service more important than design and looks? For businesses, understanding precisely how customers value different elements of a product or service allows product development to be optimised to give the best balance of features or quality, for the prices the customer is willing to pay. At a market level, conjoint analysis can be used to identify the best product range for different segments or market needs, by determining which features, value and price, across a set of products, would maximise customer value and market returns. Conjoint analysis is also known as Discrete Choice Estimation, or stated preference research and is one of a range of trade-off based research techniques. An established and powerful means of estimating customer valueWith on-going development and improvements since it was invented in the 1970s conjoint analysis has become a core tool for product planning and pricing research. By understanding precisely how people make decisions and what they value in your products and services, you can work out the sweetspot or optimum level of features and services that balance value to the customer against cost to the company and forecast potential demand or market share in a competitive market situation. It is, however, a sophisticated technique and expertise is required to ensure the design and outputs will achieve the business objectives. Conjoint principles - attributes and levelsFor example a computer may be described in terms of attributes such as processor type, hard disk size and amount of memory. Each of these attributes is broken down into levels - for instance levels of the attribute for memory size might be 1GB, 2GB, 3GB and 4GB. Play with attribute and levels in our Conjoint Explorer to see how designs can be created. From attributes and levels to product profiles and choice tasksGo Hands-on with our Conjoint Explorer These attributes and levels can be used to define different products by choosing different levels for different products so the first stage in conjoint analysis is to create a set of product profiles (possible combinations of attributes and levels) to produce a set of options from which customers or respondents are then asked to choose - know as choice sets or choice tasks. Obviously, the number of potential profiles increases rapidly for every new attribute added as the number of possible combinations increases, so there are statistical techniques and design methods to simplify both the number of profiles to be tested and the way in which preferences are tested so that the maximum amount of choice information can be collected from the smallest set of choice tasks. Choosing the right type or flavour of conjoint analysisThe precise approach to creating 'choice tasks' depends on the which type or flavours of conjoint analysis is most appropriate to use. The most common approach is choice-based conjoint (CBC), but other flavours exist. Students often get taught full-profile conjoint using ratings or cards, for more attributes adaptive designs get used, such as adaptive conjoint analysis (ACA), menu-based conjoint, or adaptive choice based conjoint (ACBC). Economists might look at Stated Preference or Discrete Choice Methods. Conjoint analysis might not be the right option. Other approaches such as MaxDiff, Simalto or hierarchy of needs studies, each have different ways to manage the balance between the number of attributes that can be included and the relative complexity of the choices that need to be shown in order to get good quality data. Statistical design and analysisA conjoint analysis study relies on appropriate statistical design in order to be able to estimate the utility models. Once all the choice tasks have been completed, analysis involves modelling what drove customers choices or preferences from the product profiles offered. The statistical output then quantifies both what is driving the preference from the attributes and levels shown - known as utilities or part-worths and importance scores. These utilities give an measurement of value for each level, of each attribute, in terms of its contribution to the choices that were made and so shows the relative value of one level against another. Market models - forecasting market potentialThe statistical output gives a detailed quantified picture of how customers make decisions, and a set of data that can be used to build market models which can predict preferences or estimate market share in new market conditions in order to forecast the impact of product or service changes on the market. For businesses this allows them to see where and how they can gain the greatest improvements over their competitors, where they can add value for the customer, how price impacts on decisions and so forecast demand and revenue. Not surprisingly conjoint analysis has become a key tool in building and developing market strategies . By combining these market models with internal project costings, companies can evaluate decisions in terms of Return on Investment (ROI) before going to market. For example determining what resources to put into New Product Development and in what areas. Choice-based conjoint or discrete choice modelling also form the basis of much pricing research and powerful needs-based segmentation . "We were looking for an agency that could understand our solutions and complex customer base in order to transfer this understanding into a comprehensive customer survey. dobney.com quickly gained deep insight into the specificities of our business and designed an excellent, state-of-the-art conjoint survey. They delivered professional and individual service of a quality we had never experienced before. It was great working with dobney.com and the findings derived from the survey are invaluable for us." Marketing Manager, Leica MicrosystemsAlternatives to conjoint - from maxdiff to configurators and e-commerce mock-ups. Conjoint analysis is relatively complex as it requires an understanding of how to use and create attributes and levels, what flavour to use, how to make the product profiles, what choice task to offer and then how to analyse the data and build the market model. It is possible to use off-the-shelf software which will provide guidance and help, but it can be also make it easy to make mistakes or generate poor designs. And conjoint analysis doesn't always fit, particularly if there are many levels, or a deeper more emotional drive to decision making. So, depending on the product or service, it is possible that off-the-shelf approaches aren't always suitable and other methods are needed. Fortunately there are a number of related approaches used as alternatives to conjoint analysis , such as MaxDiff, configurators or Simalto (also known as trade-off grids). MaxDiff is more about measuring the value from a list of items, than generating complete products, but it uses many of the same features and analytics as conjoint. Simalto, like conjoint analysis, breaks products down into attributes and levels, but then presents them as a grid of options to respondents. A range of other research techniques including menu building (building a configured product from a range of selected options), and search and filter studies in the form of e-commerce style mock-ups where respondents hunt for their most preferred products can also be used in conjunction with or as alternatives to conjoint analysis. Demonstrations and further readingTo see the mathematical workings, we have a fully worked up simple conjoint analysis worked example in Excel to show how conjoint analysis functions mathematically to estimate part-worths or utilities from design to analysis. Or just play with our Pizza demonstration which shows how utility estimations arise from choices about pizza preferences.
