Usability Evaluation

Simplification claims must be verifiable. Never assert that a redesign "improves conversion by 40%" without measurement; evaluate interfaces through structured task walkthroughs and observable completion signals.

Workflow

1. Run a Cognitive Walkthrough on concrete scenarios:
   • Select 2–3 representative user personas (e.g., a first-time user setting up a project, a developer triaging a failed run, an admin reviewing approvals) and walk through the exact steps:
     • Will the user know what to do at this step?
     • Will the user see the control that does it?
     • Will the user recognize from the label that that control matches their goal?
     • After clicking, will the user understand from the feedback that progress was made?
2. Evaluate cognitive, visual, and motor load:
   • Visual scan load: How many distinct visual groups, badges, and competing colors fight for attention on the viewport?
   • Working-memory load: Does the user have to hold codes, IDs, or previous settings in their head across screens?
   • Error-recovery cost: If the user makes a mistake (clicks the wrong filter, submits an invalid field, closes a dialog), how many steps does it take to recover?
3. Define observable verification criteria:
   • Pair every redesign recommendation with concrete criteria to verify improvement:
     • Fewer required decisions or inputs before reaching the core outcome.
     • Zero ambiguous or duplicate action labels on the screen.
     • Clear recovery path verified on empty, loading, and error states (coordinated with the exploratory QA reviewer Nova).
