DialogDesign distinguishes between products and unproducts. Unproducts are methods that we don't use, which include

·      Focus groups

In our experience, focus groups are useless for usability because they provide opinions, not actual behavior. Interview, observation, and test of real users provide results that are much more useful and reliable.

·      Eye-tracking

DialogDesign has compared eye-tracking to traditional usability testing. In CUE-6, team G used eye-tracking while all the other teams used traditional usability testing or expert reviews. The results indicate that eye-tracking is smart, but that it hardly provides results superior to traditional usability methods.

·      "Voodoo methods"

“Voodoo methods” is a common term for questionable usability methods invented by slick consultants. In fact, voodoo methods hardly foster real usability at all. The concept “voodoo usability” was introduced in an article by Jakob Nielsen.
