Usability tests
Choice of prototype advancement level and testing method
The tests were conducted online using an interactive prototype based on medium-fidelity wireframes. This choice was justified by several significant benefits:
- Greater realism
- Increased precision
- Fuller presentation of content
- Easier identification of issues
- Easier analysis of results
- Early concept evaluation
- Quick iterations
- Focus on functionality

Test results and improvements
Introduction task
Participants explored the app and described the screen. No specific tasks were performed.
Issue
Two users did not notice the ability to scroll the section providing information on the amount of whole blood and its components. The overflow area is cropped in a less visible way.
Improvement
The problem was resolved incidentally while implementing other improvements.
Task 1: Add a donation
Testers completed smoothly.
Task 2. Add a disqualification
Testers completed easily.
Task 3: Remove the disqualification
Testers completed smoothly.
Task 4. Schedule a donation
Critical issue
Users had difficulty locating the donation scheduling option due to its unintuitive placement.
Improvements
It is necessary to place the donation scheduling function where users were looking for it – i.e., in the entry type selection tab – alongside the options to add a new donation and add a new disqualification. Changes included:
Removing the option to schedule a donation from the section informing about the amount of whole blood and its components.
Adding the option to schedule a donation to the entry type selection tab.
Task 5. Check HDK badges
Users completed smoothly.
Task 6. Check notifications
Testers easily completed the sixth task, which involved checking notifications.
