8 Alternatives To Conjoint Analysis For User Research

Conjoint analysis is a popular research method for understanding which features and product attributes are most important to customers. But besides the expensive price tag associated with tools and expert support, conjoint analysis is suitable for only a handful of research scenarios.

In fact, conjoint analysis is arguably the most misused and misunderstood research method I’ve ever seen.

You can only use conjoint analysis when your research meets all of these criteria:

1. You’re trying to simulate a purchase scenario between similar products.
2. Where only one person is involved in making the purchase decision.
3. Where that customer already knew what kind of product they needed.
4. Where you already know which attributes they use to compare products.
5. Where those attributes have no overlap in meaning or possible options.

This means conjoint analysis is really only suited for research like market share modeling, calculating willingness-to-pay for existing product attributes, or informing product bundling strategy.

So if you found this article because you were hoping to use conjoint analysis to do discrete-choice research to understand what matters most to customers, then I have some good news for you. There are a bunch of other choice-based research methods made for user research that come without the hefty price tag, complexity, and rigidity of conjoint analysis.

What Is Choice-Based Research?

Choice-based research (or choice modeling) is a survey format where respondents are forced to pick between a set of options. It’s used to measure which options are most important to people.

Choice-based research is particularly valuable because it imitates real-life scenarios where people must consider trade-offs and make a choice between different options, making it a great way to inform strategy and prioritization decisions.

Whether you’re trying to figure out which problem is your customers’ highest priority to solve, which feature users get the most value from, or which idea your teammates feel will be most impactful, choice-based surveys are an easy way to collect this data.

4 Choice-Based Research Methods To Try Instead Of Conjoint Analysis

Pairwise Comparison

Explanation: Pairwise Comparison is like a simple, flexible version of conjoint analysis. Instead of showing people “profiles” made up of many different attributes, pairwise comparison shows two options at a time and calculates which options get picked most often.

Example:

Advantages: Simple to set up on your own, low cognitive load for participants, can rank short or long lists, easy to understand how results are calculated, 10x cheaper than conjoint analysis tools.

Disadvantages: Lacks some of the sophistication of conjoint analysis (eg. separate attributes and levels). Can require a lot of voting if you’ve got a lot of options but only a few respondents.

Suggested Tool: OpinionX (unlimited free Pairwise Comparison surveys)

Points Allocation

Explanation: Points Allocation surveys give respondents a pool of credits to spend amongst a set of options. The way they allocate those credits tells you not only which options are most important to them, but also how much more important the top options are.

Example:

Points Allocation Constant Sum Conjoint Analysis Alternatives for Trade-Off Pricing Willing To Pay Research

Advantages: Great at measuring the magnitude of people’s preferences by allowing them to “spend” their credits on what matters most to them (ie. not just that they like apples more than pears, but they would give 9 of their 10 points to apples). Points Allocation is more flexible than conjoint analysis for testing willingness to pay for specific functionality or benefits.

Disadvantages: As a method of choice-based modeling, respondents may feel so strongly about a few options that they choose not to allocate any points to many of the options available. While this is a solid indicator that it is not important, it can create gaps in data (particularly with smaller respondent sample sizes).

Suggested Tool: OpinionX (unlimited free Points Allocation surveys)

Ranked Choice Voting

Explanation: Ranked Choice Voting shows respondents the full list of options and asks them to rank them according to their personal preferences.

Example:

Advantages: It’s a well-known ranking method that’s easy to set up and very simple for participants to use.

Disadvantages: You can only use 6-10 options max in a ranked-choice question before your quality of data starts to decline sharply. For ranking 10+ options, consider using Pairwise Comparison instead. Ranked choice voting is not particularly easy to do on touchscreens/mobile phones, however, many tools have adapted the design to make this easier (eg. OpinionX and Tally allow users to rank by tapping options, as well as with arrows to reorder their choices).

Suggested Tool: OpinionX (unlimited free Ranked Choice Voting surveys — optimized for any screen size)

MaxDiff Analysis

Explanation: MaxDiff Analysis shows respondents a list of options (usually 4-7 at a time) and asks them to identify the “best” and “worst” options from the list. Each time the respondent has finished, the list resets and a new set of options are shown.

Example:

Advantages: By showing 4-7 options at a time, MaxDiff collects more data per vote than pairwise comparison. It is also much less rigid and complex to set up than a Conjoint Analysis survey.

Disadvantages: MaxDiff has multiple times higher cognitive load than pairwise comparison by showing 4-7 options at a time instead of just 2. While this speeds data collection up, it slows the participant down considerably and requires more “considered” judgment for each vote to be reliable. Additionally, MaxDiff tends to be pretty expensive with a similar price tag to conjoint analysis tools.

Suggested Tools: Sawtooth Software ($3,300/year for only MaxDiff), QuestionPro’s “Research Suite” Package ($5,000/year), Alchemer’s “Full Access” Package ($1,895/user/year). Compare the 10 most popular tools for MaxDiff Analysis to learn more.

4 Other Research Alternatives to Consider

Agreement Voting

Explanation: Measures which option has the highest level of consensus agreement amongst a population of voters.

Example:

Advantages: In many scenarios (collaborative planning, educational settings, conflict resolution), it’s more important to identify consensus options that will move progress forward than to find a divisive option just because it has the highest number of votes. Agreement voting is extremely simple, quick, and easy to understand for both researchers and respondents.

Disadvantages: Agreement voting has no forced comparison or trade-off, so it doesn’t do a good job of simulating how people act in real life. Simple aggregate voting like this should not be used in most research scenarios.

Suggested Tools: OpinionX (unlimited free Agreement Voting surveys)

Kano Model

Explanation: The Kano Model shows a respondent a statement (usually about a specific feature or product functionality) and asks them to select one of five options: (1) I like it, (2) I expect it, (3) I am neutral, (4) I can tolerate it, (5) I dislike it.

Example:

Kano Model Alternatives to Conjoint Analysis Trade-Off Choice-Based Modeling

Advantages: The main advantage of the Kano Model is that it helps you distinguish which features are expected (basic), which contribute to satisfaction (performance), and which can lead to delight (excitement).

Disadvantages: In my opinion, the Kano Model is not a good approach to trade-off analysis or understanding what matters most to people. It requires respondents to have a very clear understanding of the value that each individual feature translates into for them, which is rarely the case. It’s also a glorified 1-5 star rating scale, which has many proven issues in research, particularly for allowing respondents to pick the same score for every option and for not forcing any comparison between options, which is a fundamental aspect of trade-off analysis.

Suggested Tools: Any survey tool with a multiple-choice question or matrix grid.

Van Westendorp PSM

Explanation: Conjoint analysis is famous for pricing research, however, it can only be used if you already have a range of 2-7 potential price points you’re willing to consider for your offering. For many new products, particularly in emerging categories or based on technical innovations, you won’t have any benchmark price to even start at! That’s where the Van Westendorp Price-Sensitivity Meter comes in. It uses four open-response questions to help you find a reference point for what your initial pricing should be.

Example:

Advantages: Great for identifying a rough range of price points to consider for a new product or service. Simple setup and analysis that anyone can do. No advanced survey tool required.

Disadvantages: Only suitable for finding pricing estimates, not any other form of research, so it’s very narrow in usage.

Suggested Tools: Honestly, no need for any fancy tools here — just use a Google Forms questionnaire or a free OpinionX survey to collect people’s text response answers and manually create your Van Westendorp PSM graph in a spreadsheet.

TURF Analysis

Explanation: TURF Analysis isn’t actually for data collection like the other methods shown. It’s a data analysis method that takes ranked data and finds the combination of options that have the highest combined preference that appeals to the most people possible (basically which two options are highly ranked but with very little overlap in who cares a lot about them).

Example:

Image Source: Quantilope

Advantages: TURF Analysis is predominantly used for informing product bundling strategy, where it’s very useful in product or attribute mix selection.

Disadvantages: As it’s not a data collection method like the other alternatives, TURF Analysis relies on using an approach like Pairwise Comparison, MaxDiff or Conjoint Analysis to calculate the relative importance of each option first. It’s also only really useful when looking for the lowest input approach to maximizing output effect, which is not a common research requirement.

Suggested Tools: Sawtooth Software ($4,500/year for TURF Analysis) or QuestionPro’s “Research Suite” Package ($5,000/year).

How To Pick The Right Choice-Based Research Method

If you’re trying to model market share scenarios, calculate willingness-to-pay for existing product features, or simulate competitor comparisons in mock buying decisions, then it’s hard to beat conjoint analysis. But the vast majority of research projects people consider conjoint for are not made for conjoint, so pick a more flexible, easier-to-use method that’s available for a much cheaper price (or even for free) instead.

Here’s a final graphic that explains the difference between the various choice-based research methods I’ve covered in this blog post:
