The filter and comparison feature posed usability challenges during testing.
In early iterations, users struggled to grasp how to filter original data and compare it to a modified set – only 71% understood the workflow in Iteration 1, and just 50% in Iteration 2 due to confusing tab structures.
In Iteration 3, I redesigned the flow as a guided workflow, requiring users to apply a filter before enabling comparisons. This streamlined approach improved comprehension to 88%, with users successfully completing the task and understanding the connection between filters and comparisons.
