Common Mistakes
In teaching people to use the walkthrough method, Lewis & Rieman have found that there are two common misunderstandings :
- The evaluator doesn't know how to perform the task themself, so they stumble through the interface trying to discover the correct sequence of actions -- and then they evaluate the stumbling process. (The user should identify and perform the optimal action sequence.)
- The walkthrough does not test real users on the system. The walkthrough will often identify many more problems than you would find with a single, unique user in a single test session.
