ROI of Usability: A Collection of Links

Update (Feb 2004): New updates to this topic will be posted here. After a few years of collecting links and organizing articles and doing consulting gigs on this topic, we are finally getting around to writing some articles. Check back here in a month or so.

It is hard to directly estimate the economic impact of usability. However, it is important to do so, both at the macro and the micro level. Products with bad usability can have impact in terms of wasted time, erros, unfinished tasks, frustration, and even medical problems such as RSI. A concrete calculation of usability impact is difficult, but is often needed by usability advocates within companies, independent consultants etc. Below, I am collecting links to articles and cost-benefit calculators for estimating the economic impact of usability.

Email me if you know of any good article on ROI that I have missed.
