Usability Issues
With our specific task flow selected, we evaluated the current screens and experience of loading funds onto your Presto card and identified various heuristic violations and usability issues. Below are the 6 screens/steps in the task flow that we thought could be improved.
Stage 1: Select Load Amount
Heuristic Violation 1: Error Prevention
Severity Rating: 2.
Usability Issues:
- It’s easy to miss selecting a payment method before pressing “Buy Now”.
- The “Buy Now” button appears in an active state despite missing information (entering the amount of money you want to load and selecting a payment method are both required to move forward).
Recommendations:
- Add radio buttons next to the payment methods to indicate that the user must make a selection.
- Leave the “Buy Now” button grayed out until the user has inputted all the required information.
