How many of the usability problems identified in a heuristic evaluation are true usability problems? Several years ago, I published an article suggesting that many of the 'problems' identified by heuristic evaluators were not problems at all (Bailey, Allan and Raiello, 1992). Even so, many of us have continued to waste time and go to the expense of fixing many usability problems that were not problems. Recently, three research papers were published that provided some insights into the validity of heuristic evaluations (Catani and Biers, 1998; Rooden, et.al., 1999; Stanton and Stevenage, 1998). The articles discussed usability testing in three totally different domains with very similar results.

Abstract: How many of the usability problems identified in a heuristic evaluation are true usability problems? Several years ago, I published an article suggesting that many of the 'problems' identified by heuristic evaluators were not problems at all (Bailey, Allan and Raiello, 1992). Even so, many of us have continued to waste time and go to the expense of fixing many usability problems that were not problems. Recently, three research papers were published that provided some insights into the validity of heuristic evaluations (Catani and Biers, 1998; Rooden, et.al., 1999; Stanton and Stevenage, 1998). The articles discussed usability testing in three totally different domains with very similar results.
