Research output: Chapter in Book/Report/Conference proceedingChapter or book articleProfessional


In this paper the development of a human factors engineering evaluation method is described. The method is called Contextual Assessment of Systems Usability (CASU). It is designed for performance-based integrated validation of complex system interfaces. The paper describes the design rationale of the method and the process of its development. It also makes explicit the structure of inferences that results in evaluations concerning systems usability. The major evaluation dimensions are facilitation of the core task and support for the three main functions of tools in the control of the process, the instrumental, psychological and communicative functions.
