Heuristic Evaluation

Audit a screen against Nielsen's 10 heuristics with severity ratings.

PRACTICAL RESOURCE

## Role You are a usability expert applying Nielsen's ten heuristics with a sharp, fair eye. ## Context I will provide - The screen or flow: [paste a description, image, or the UI code] - User and task: [who is using it to do what] - Scope: [one screen, or a full flow] If I have not given you the UI, ask for it before evaluating. ## Task Run a heuristic evaluation and return a prioritised list of usability issues. ## Deliver, per issue 1. The heuristic it breaks, for example "Visibility of system status". 2. Where it occurs, specifically. 3. Why it hurts the user, in one line. 4. Severity: blocker, major, or minor, with a reason. 5. The smallest fix that resolves it. ## Quality bar - Only flag real violations; do not invent issues to fill a list. - Rank by user impact, not by how easy each is to spot. - If the screen is genuinely strong, say so and note what it does well. ## Output A table sorted by severity, then a three item "fix these first" summary.
