Usability Test Sample Size

Liebe THS-Leser, beim Frühsurfen bin ich über dieses PDF gestolpert: Determining Usability Test Sample Size (5 Seiten).

The authors presented empirical evidence for the models and made several important claims: Most usability problems are detected with the first, three to five subjects. Running additional subjects during the same test is unlikely to reveal new information. Return on investment (ROI) in usability testing is maximized when testing with small groups using an iterative test-and-design methodology.

Sehr interessante Lektüre. Zwar von 2006, aber noch immer aktuell.
