SUE: Systematic Usability Evaluation
Tuesday, February 24th, 2004
Usability is an important facet of the overall quality of interactive applications. SUE (Systematic Usability Evaluation) is a methodology that provides a systematic and organized way of conceiving and conducting a usability evaluation process. It introduces a number of important novelties and combines existing approaches (inspection and empirical testing) in an original way. In this paper we describe the use of SUE for hypermedia applications, and focus on two specific aspects: abstract tasks and concrete tasks. Abstract tasks are generic activities that an expert evaluator must perform during the inspection, in order to come up with a description of the application and to guess potential usability problems. Concrete tasks, systematically derived from abstract tasks and inspection results, are specific activities that end users must perform during empirical testing. Examples of abstract tasks and concrete tasks are described, and fragments of the evaluation of three CD-ROM’s are presented.
