During this user usability test, I have three users test the application developed for Polly and Sam mainly.
Most of them are confused at very first on the tile page. After they read the instruction about how the tiles work they seemed to like the idea.
They also ask questions about why I incorporate metrics like Tax and GPA in the tile view, and I explained though it does not have a lot to do with the usability test.
I assigned four tasks to the users and they all completed them in a reasonable time period, which means the navigation is qualified of this application.
The questions here include limited demonstration of necessary information, the insights panel approach methods and the color of the two KPIs.
