Review the interface against Nielsen's 10 heuristics one by one, checking concrete items like loading indicators, undo options, and plain-language error messages. Record each heuristic as pass, partial, or fail, then summarize the overall score and priority fixes.

They are ten interface design principles from Jakob Nielsen (1994): visibility of system status, match with the real world, user control and freedom, consistency, error prevention, recognition over recall, flexibility, minimalist design, error recovery, and help documentation.

Nielsen's heuristics evaluate screen-level interface quality such as feedback, consistency, and error handling. Downe's 15 Good Services principles evaluate end-to-end service quality. The two complement each other for user-facing work.

Run it during delivery review for any user-facing work, after UI implementation and before marking delivery complete, or whenever users report confusion or friction with an interface.

A heuristic evaluation catches common design violations but does not replace testing with real users, since experts may miss issues actual users encounter. It also depends on reviewer judgment when rating items as pass, partial, or fail.
