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.

Famous quotes containing the words common and/or mistakes:
“Thus Pegasus, a nearer way to take,
May boldly deviate from the common track.
From vulgar bounds with brave disorder part,
And snatch a grace beyond the reach of art,
Which without passing through the judgment, gains
The heart, and all its end at once attains.”
—Alexander Pope (16881744)
“Certainly, the mistakes that we male and female mortals make when we have our own way might fairly raise some wonder that were so fond of it.”
—George Eliot [Mary Ann (or Marian)
