I led heuristic evaluation for multiple VISA websites and applications. Transaction Search application is one of these projects.
Background: Transaction search is a service that VISA clients can retrieve and review all the transactions through VISA. When the Cybersource team was working on the transaction search project, the front-end engineer team asked our UX team to help them make the application more user friendly before the back end development starts. But they didn’t have time to conduct usability testing. So we offered a heuristic evaluation study.
Challenge: The development team wanted to make the design modern. But the prototype went too far away and neglected the usability. We needed to persuade all the developers to change their mind into user first.
Research and strategies: I studied the application prototype and analyzed each page. Based on my UX thinking, I found users may need multi-feature search, so I designed and added it to the report. For better persuasion, I provided visible design recommendations in the report with statement of issues I uncovered.
Main design recommendations (the following pictures are examples):
- Add multi-feature search
- Remove search results cards from result details page
Result: The development team accept almost all our recommendations and implement them into the final version of the product.
