Abstract : We present a detailed case study, drawn from many information sources, of a computer scientist learning and using Cognitive Walkthrough to assess a multi-media authoring tool. We then compare the predictions produced by the analysis to the usability problems actually found though empirical usability tests. This study results in several clear messages to both system designers and to developers of evaluation techniques: (1) the Cognitive Walkthrough technique is currently learnable and usable, but (2) it may not predict most usability errors found empirically, and (3) several elaborations of the technique might improve its effectiveness. In addition, the emergent picture of the process this evaluator went through to produce his analysis sets realistic expectations for other novice analysts who contemplate learning and using Cognitive Walkthroughs.
