CT-UT Exam Dumps : ISTQB Certified Tester Usability Tester

The described issue violates the usability heuristic “User control and freedom,” as defined by Jakob Nielsen. This principle emphasizes that users should have the ability to undo and redo actions and navigate freely without being trapped in irreversible sequences. In the scenario, users are forced into the checkout process without a clear way to return or correct mistakes, except through the unreliable and disruptive back button. This design flaw undermines user autonomy and can result in lost progress or frustration.

Usability test reports are more effective when they are balanced and include not only problems but also what worked well. Including positive findings increases credibility, encourages the development team, and helps them understand what should remain unchanged. Option B violates privacy and ethical standards. Option C may dilute focus, and D could worsen the problem by making the report less accessible. Thus, the best practice supported by usability.gov and Nielsen Norman Group is to include both positive and negative findings.

In usability evaluations, a distinction is made between actual usability problems (where a user struggles to complete a task or is confused by the interface) and suggestions or ideas that users provide based on their preferences or perceived improvements. When a participant offers a new feature idea (such as a quick search box), this is classified as a “good idea” or “feature suggestion,” not necessarily a usability problem. It may inform future design enhancements but does not indicate a failure in usability for existing functionality.
