Talk:Usability testing

This is a rather idealized definition that does not take into account the broad diversity of what people do under the label of "usability testing". In my experience, "usability testing" is a label for a very large number of different techniques for assessing a product. Even with this narrow definition, there's strong evidence that usability testing practices are so diverse that they aren't comparable, or at least not to the point where it is meaningful to discuss topics such as the proper number of test participants. Certainly, most "usability tests" are not controlled experiments. -- Ronz 15:31, 28 April 2006 (UTC)
