Usability Testing Report

In this Usability Testing, the participants were able to complete the given scenario task. All participants agreed that the new design made it easier for them to complete the task.

However, there are still some things that need to be improved, such as the use of uppercase and lowercase letters in the design. There are still many that look inconsistent. Then, writing on the notification above the basket button would be better placed in a visible place so that the user would notice it.

Key Findings

1. 5 out of 5 interviewees said the new design is easier and clearer compared to the previous app design
2. 3 out of 5 interviewee mentioned that they didn’t notice the notification above the Basket button because it is too small
3. Some writing still shows inconsistency
