Discount Usability for the Web

January 1, 1997

Discount usability engineering is our only hope. We must evangelize methods simple enough that departments can do their own usability work, fast enough that people will take the time, and cheap enough that it's still worth doing. The methods that can accomplish this are simplified user testing with one or two users per design and heuristic evaluation.

Characteristics of Usability Problems Found by Heuristic Evaluation

Heuristic evaluation is a good method of identifying both major and minor problems with an interface, but the lists of usability problems found by heuristic evaluation will tend to be dominated by minor problems, which is one reason severity ratings form a useful supplement to the method.

Severity Ratings for Usability Problems

January 1, 1995

Rating usability problems according to their severity facilitates the allocation of resources to fix the most serious problems. Severity ratings are a combination of frequency, impact, and persistence.
