Heuristic Walkthrough

A usability evaluation method proposed by Andrew Sears (1997) that combines scenario-based cognitive walkthrough with heuristic evaluation. Evaluators work through realistic user tasks using a prioritised list of heuristics, surfacing both task-specific and general usability problems. In accessibility work the method is adapted as the Barrier Walkthrough, which substitutes disability-specific barrier categories for generic usability heuristics. Compared with pure heuristic evaluation, the walkthrough structure reduces false positives by grounding each finding in a concrete user goal.
