Formative and Summative

Hier, liebe THS-Leser, ist was kurzes und gutes für Euch: Are the Terms Formative and Summative Helpful or Harmful?

Most usability testing involves finding and fixing problems as part of an iterative design process to make an interface more usable. It is typically called a Formative Usability Evaluation. In contrast, a Summative Usability Evaluation describes the current usability of an interface—as measured by things like task times, completion rates and satisfaction scores. Summative tells you how usable an interface is and formative tells you what isn't usable.

Nette, praktische Betrachtung.
