What is Pilot Testing?

pilot testing

Pilot testing in user research is conducting a small-scale version of your research before moving on the the full-scale implementation of your research study. This can take the form of small-scale product trials or testing of features. The main goal of the pilot testing is to assess the feasibility of your research study, catch any issues early in the process, and ultimately fine-tune your research.

Conducting a pilot test can help you get the most out of your research study when it is in full swing ensuring it goes as intended and doesn’t cause any confusion for the participants.

Why is Pilot Testing Important?

Although pilot study in research is often overlooked, it presents a host of advantages. It can serve as an evaluation mechanism that can have a great overall impact on the effectiveness and success of your research. Here is how:

Testing the feasibility of the full study

Pilot testing is a great way to check if your research study is feasible when it comes to scope, time, and budget. By conducting one, you can get a feel for the resources needed for your study and make the necessary decisions around the scale of your full study.

Ensuring the validity of your research methods

Another great advantage of a pilot study is that it allows user researchers to assess the validity of their research methodologies. Pilot testing can help you ensure that the selected method is indeed the right one and that it is in line with the goals of the research study. On top of that, it can also help you identify any issues in the implementation of the method that you can fine-tune before launching a full-scale study.

Getting a quick feel of the data

A pilot test can be a great way to gather quick insights on a new product or feature. These data although not conclusive can give you a feel for the user behavior and can result in tweaks or adjustments in the research plan or the participant recruitment methods.

Spotting the issues

Pilot testing is a great method for uncovering confusion areas in your tests. It helps to assess the comprehensiveness of your tasks and questions, ensure that participants understand the instructions, etc. If there are any issues with the study, like confusing wording in the tasks or overuse of professional jargon, pilot test helps to pinpoint those and fine-tune your study.

This helps to ensure that the results you get will be accurate and relevant, corresponding to the goals of your research.

Types of Pilot Testing

In the context of user research, pilot testing can be applied both in qualitative and quantitative research.

1. Pilot Testing in Qualitative Research

Pilot testing in qualitative research revolves around building a rapport with the participants. The sessions are typically conducted either on a one-on-one basis or in focus groups. The environment in this type of research should provide a safe space for the participants to express their thoughts while being closely watched.

Pilot test in a qualitative research context can be a great way to validate the study’s logic. It can verify whether the tasks have a logical sequence and are understood by the participants. It also serves as a great indicator of the actual time needed to complete the full study. 

Based on the results of the pilot study,  user researcher can then further refine the information presented to the participants and the way the study is structures, to maximize the success of effective data collection.

2. Pilot Testing in Quantitative Research

When it comes to pilot testing in quantitative research the focus revolves around addressing aspects like removing bias in the research questions or refining the conditional logic applied. Again very much like in the qualitative research setting, this proactive approach allows UX professionals to refine their study before moving head first into the full-scale implementation.

For example, you’re conducting a quantitative study to assess the effectiveness of a new mobile app feature by distributing a survey to your users and asking for feedback. By running a pilot test first, you’re able to identify any unforeseen issues with the survey design, such as confusing questions or technical glitches. By analyzing the responses and feedback from this initial group, you can then modify the survey to ensure clarity and functionality.

This refinement process not only enhances the accuracy of the final study but also ensures that the results are reliable and can be generalized to a larger population with greater confidence.

Beta VS Pilot testing 

While both beta testing and pilot testing are product testing methods they are used in different stages of product development and they serve distinct purposes. Here is a handy table to better understand the two testing methods.


Beta Testing

Pilot Testing


Gathering user feedback before the product’s full release and after the initial testing also known as alpha testing.

To assess the comprehensiveness and effectiveness of your research study.


The scope of beta testing is broad covering the overall user experience.

The scope of pilot testing is narrower and laser-focused on the feasibility and validity of the research study.

Main Goals

To assess the readiness of the product and uncover any last-minute issues.

To identify potential bottlenecks in the research methodology and the test itself, ensuring that it aligns with the scope of the study and doesn't cause any confusion. 

How to Conduct Pilot Testing in Research?

If you are looking to validate the reliability and validity of your research study before diving head first into it, then pilot testing is the way forward. Here is a step-by-step process on how you can hit the ground running by conducting your pilot study.

1. Set clear Objectives

Depending on the nature of your full study and your chosen methodology, set clear goals and objectives for the pilot testing. For instance, if you are examining a user interview your goal might be to assess if the questions are clear or if they are presented in a logical order.

Alternatively, if you are assessing the overall feasibility you might want to laser focus on finding out more about things like time and resource requirements for the full study.

2. Recruit the Participants

Start recruiting participants that align with the target audience of the study that you are piloting. Online communities, an internal user base, or social media are all excellent platforms to recruit a diverse sample of participants for your pilot tests.

Remember, you don’t need the same amount of participants for the pilot test, as you recruit for the actual study. A common rule of thumb is to use a sample size of 10 to 20% of your full-scale study participants. A pilot test with 2-3 people is usually more than enough to spot critical issues and assess your study’s comprehensiveness. Base the amount of people you pilot test with on the budget and time available for the study.

3. Conduct the Pilot Test

Now you are ready to conduct pilot testing! Make sure to brief your participants and closely observe the testing. Look out for bottlenecks, unexpected challenges, or sticky points in the flow of the study. Do not forget to keep a detailed record of the timings of the tests. 

If you’re testing an unmoderated study, make sure to moderate the pilot tests for it, so that you can spot the critical issues that may be otherwise overlooked.

4. Analyze your findings

Carefully collect the data that you gathered based on your set objectives and start analyzing them. Look out for patterns, paying particular attention to the areas that need improvement. 

5. Determine your action plan

Based on the findings of your analysis you can then determine an action plan. This might mean that you need to further refine your research questions, adjust the testing script or even fine-tune your data collection methods.. 

Consider the overall importance of the issues that you identified during the pilot test and the impact that those might have on your study further down the line.

Best Practices for Effective Pilot Testing

Here are some golden rules to follow to ensure an effective pilot test:

Know your Success Criteria

Ensure you have set measurable benchmarks and success criteria before conducting your pilot study. If you fail to do so, you can easily lose sight of the goals of your testing and further move away from finding a way to resolve any issues. 

Select a Representative Sample

The validity of your findings highly depends on the quality of your participants. Ensure that you have selected a representative sample of your target population that will allow you to generalize the results.

Establish a Communication Plan

Having a clear communication plan to ensure that the different stakeholders are well-informed is another golden rule when it comes to effective pilot testing. Pilot testing might bring to the surface greater product issues so keeping stakeholders in the loop is of utmost importance. 

Conduct a Debriefing Session

Another best practice when it comes to pilot tests is conducting a debriefing session with the research team right after. This can foster a constructive dialogue where members will be encouraged to share insights and perspectives, facilitating a better understanding of the outcomes of the pilot testing. 

Mistakes to Avoid in Pilot Testing

Interpreting the results of pilot testing can be tricky enough, so make sure to avoid the below pitfalls that can jeopardize the validity of the results of your pilot test: 

Not Having a Representative Sample

Choosing participants who do not represent your user personas is one of the greatest pitfalls in pilot testing. As tempting as it might be to start recruiting random participants for time-saving purposes, this can dilute the validity of your pilot testing results. Make sure to always recruit a representative sample that falls under the traits and demographics of your intended users. 

Overgeneralizing Results from Pilot Testing

Overgeneralizing your results is another grave mistake that needs to be avoided at all costs when it comes to pilot testing. Always consider the limited scale and scope of the pilot study and do not overgeneralize the findings as those might fail to capture the complex nature of the entire study.

Ignoring Participants’ Feedback

Ignoring the feedback that the participants of the study are giving you is another very common mistake. Do not become defensive of your work and never underestimate the importance of the feedback that is gathered during your pilot testing.

Insufficient Planning

Finally, another major pitfall when it comes to pilot testing is insufficient planning. Conducting a pilot test without a thought-through clear plan can lead to further confusion instead of clarity. Make sure to craft a highly detailed plan and set clear procedures to ensure accurate findings. 

To sum up

Pilot testing is a unique tool that gives UX researchers and designers an unmissable opportunity to assess their research studies before engaging in the main endeavor.
