What Is Mobile Usability Testing? 

Mobile usability testing is the process of gathering information about users and how they interact with your application to make it better and offer your users a perfect experience. Mobile app usability testing allows you to understand the validation of your hypothesis and if some elements need changing, identify and fix usability issues, and make informed decisions. 

When Is the Right Time to Conduct Mobile Usability Testing?

You can conduct mobile application usability testing at three stages: 1) prototype usability testing, 2) MVP usability testing, and 3) post-launch usability testing.

You use prototype testing when you have just started developing ideas, providing the requirements for the app, and gathering information about your target audience.  

The initial version of your product is called MVP. Minimum viable product usability testing helps you understand if your assumptions were right. Conducting a usability test at this stage can save lots of effort and money because it determines if continuing to develop this product is the right choice.

You should also run usability testing after you launch the app. You do this by collecting data around the product usage and if users can navigate the app smoothly. 

Apart from what we discussed here, there is an optimum time to conduct usability testing. Click on the link and read the article if you want to know when it is.

How to Conduct Mobile Usability Testing? 

To run a successful mobile user testing, you need to follow some steps and rules. Stay with me to learn more.

1. Set the Objectives of the Mobile Usability Test

Regardless of where you are in the app development process, you must have some goals before conducting a test. If you don’t have an objective, then what are you even going to test? Wouldn’t it get chaotic? You also need goals so you can create the right tasks for your users. Here are some examples of  app usability testing goals:

  • Is navigating the app easy?
  • Are there any bugs or errors?
  • How are key functions working?

2. Choose the Tasks Your Participants Are Going to Perform

Now is the time to create the tasks you want your test participants to perform. But don’t just ask them to complete tasks. Make real-life task scenarios so users can actually imagine themselves in that situation. Here’s an example:

  • It’s a Sunday night. You plan to go out with your friends. You want to feed your cat before leaving, but dang! You’ve run out of it. You want to order some immediately. Open the app and order some cat food. 

3. Assign Roles to Your Team Members 

Any kind of usability test needs a facilitator. The facilitator observes and instructs test participants while performing a task or working with a product. You can assign roles to your other team members, such as a note-taker. 

4. Recruit the Test Participants

Your test participants should represent your target audience if you want real results. If you create a buyer persona and identify your ideal customers, then reaching out to them will be an easy job. You need to know information about your users, such as their demographics and psychographics, so that you can define your ideal participants. 

5. Determine Your Mobile Usability Testing Method 

When conducting usability testing for mobile apps, you can use two methodologies: 1) moderated vs. unmoderated, 2) remote vs. in-person. 

A moderator is required in moderated usability testing. The moderator watches as sample groups complete tasks or work with a product. In this type, they can guide participants, answer their questions, ask follow-up questions, and control the sessions. 

In contrast, an unmoderated usability test is held without direct supervision. In this type, users often work and interact with a system as a session recording records their interactions. You can’t gather in-depth data compared to moderated tests; however, it’s so much cheaper, needs fewer resources, and is less time-consuming. 

In the remote usability testing, the moderator and the participants don’t need to be in one place. Usually, businesses choose remote usability testing since traveling is hard for users, and if they agree to travel, it’s going to cost you a lot. You will also need a lab to hold the test there. This method is suitable for wealthy companies needing in-depth and detailed data. 

6. Conduct a Pilot Test

One of the usability testing best practices is to conduct a pilot test a few days before the actual test. This helps you identify any probable issues and prevent having problems while running the test. 

7. Analyze and Report Your Findings 

After you conduct your mobile usability testing, it’s time to analyze your results. Usually, several issues are found in a usability test, and you have to prioritize them. 

You also have to report your findings backed up by qualitative and quantitative data. This is important because you will have the data in one place in case you need it in the future.
