Heuristic Evaluation

A heuristic evaluation is a review where experts inspect an interface against a set of established usability principles to find problems.

Why it matters

It's a fast, low-cost way to catch many usability issues without recruiting users, often as a first pass before testing.

In depth

The best-known set is Jakob Nielsen's 10 usability heuristics — including visibility of system status, match with the real world, and error prevention. A few evaluators reviewing independently find more issues than one. It complements, but doesn't replace, testing with real users.

Real-world example

A designer reviews a checkout flow against Nielsen's 10 heuristics and flags that the system never confirms a successful payment.
