Heuristic Evaluation Topics

How Effective are Heuristic Evaluations?

Jeff Sauro • September 6, 2012

A heuristic evaluation of two websites from four evaluators found 32% of the issues 50 users had during a usability test. Heuristic evaluations typically find between 30% and 50% of issues found in usability tests. In general, HE is best used in addition to usability testing to generate the most complete picture of potential and actual interface problems.[Read More]

Jeff Sauro • August 14, 2012

Cognitive Walkthoughs have more of an emphasis on the learnability of a task. Both methods are best performed with multiple evaluators.[Read More]
