CUE-5 - IKEA PAX Wardrobe Planner

CUE-5 is a comparative usability evaluation of the PAX Wardrobe planning tool on IKEA’s website, www.ikea-usa.com.

The evaluation was conducted in October 2005 as part of a Usability Practicum in connection with the UI10 conference in Boston, Massachusetts.

Thirteen professional teams simultaneously and independently evaluated the website’s usability. Five teams used usability testing (two of these teams used remote usability testing), and eight teams used their favorite expert review technique.

Interesting observations from CUE-5

·      There are considerable differences in the number of key issues that the various teams report.
A "key issue" is an important usability issue on which many teams agree. For a more precise definition and discussion of this quality measure see our CUE-4 paper.

·     The number of hours used for the evaluations seems to correlate weakly with the number of key issues reported, but there are remarkable exceptions.

·      Expert review teams use fewer resources on the evaluation and in general report fewer key issues, but in general their results are fully acceptable.

·      The teams reported surprisingly few positive issues, and there was no general agreement on them. Many positive issues were reported by single teams only. You might ask whether the PAX Planner is really that bad, or if usability professionals are reluctant to report positive findings.
