Usability testing is a type of qualitative research applied to websites, applications, e-commerce, digital platforms, or physical products.
In this type of research, we recruit people who represent the target audience of a product, plan tasks for them to perform, and then track and measure how they perform these tasks.
Ideally, usability testing should be applied continuously.
Since we know that day-to-day realities can prevent this continuous monitoring, a usability test can be applied at 4 stages of a product’s development:
The sooner we apply testing to a product, the more we can improve it.
There are four types of usability testing:
Generally, the more user interaction we have, the more insights and information we can gain.
According to a 1993 study by Jakob Nielsen, a usability test should ideally have five users of each profile. With this number, it is possible to discover at least 85% of a product’s usability problems. Beyond this number of participants, the cost-benefit of the project is not so interesting.
Nielsen argues that we learn as we test with each user. In the first test, we have an overview of the product; in the second test, we will already have common points with the first test, and so on. By the fifth test, we already have a broad view of all the necessary improvements.
Generally speaking, a usability test is basically composed of 6 stages:

The whole process carried out by Tuia is very well structured and brings us very significant results. I rate it as a good experience. The suggestions for change and improvement that are sent to us in the report through the analysis of the user responses are always considered in our refinement meetings.
