Abstract:

A world wide expert review competition sponsored by Intuit and Infosys Technologies Ltd. was hosted by the Usability Professionals' Association, Bangalore on World Usability Day, 2007. The purpose of this competition was to expose all to a simple, yet powerful usability technique: heuristic evaluation. It also served to gather data to define heuristic expertise standards at a global level. This is critical as this popular and valuable technique is used by 76% of the usability community (UPA Survey, 2005) and it shows a cost-to-benefit-ratio of 1:48 (Nielsen, 1994). By defining these standards we can ensure that evaluations are of a certain standard.
