Poster #6: Developing Guidelines for Judging the Cost and Benefit of Fixing Usability Problems
by Heather L. McQuaid, MAYA Design, Inc.

| When we conduct an expert analysis, we evaluate an interface for usability problems and
then prioritize those problems according to importance (i.e., how important it is from the
users’ and client’s perspective to fix the problems) and difficulty (i.e., how difficult it is
from the designers’ and developers’ perspective to fix the problems). By mapping the
cost and benefit involved in fixing problems, we essentially give clients a sense for the
return-on-investment (ROI) they could gain by addressing the problems. When we
presented our method at usability and human-computer interaction conferences, the
question we were most asked was, “How do you determine the benefit to users, and the
cost to developers, of fixing problems with a product?” This poster represents our first
pass at outlining the guidelines we use to judge importance and difficulty.
