I  tested my prototypes with real users.

I created a test plan and a test script. Then I gave the interactive prototype to potential users to test the basic functionality, screen layout and user workflow.

Used Affinity Map to isolate information from interview data. This certainly helped to visualize bits of information.

At this stage, I went back and refined prototypes after getting  critical feedback from users.

After a few iteration rounds, I increased the fidelity of my wireframes and tested them again.
