Abstract

Interactive systems have to fit the needs of their users. In an evolutionary development cycle, the evaluation of existing systems serves as a foundation for designing improved systems that better fit people's needs. Few evaluation methods encourage the analyst to step back and consider how well a system supports users' conceptual understandings and system utility. CASSM, the approach presented in this course, focuses on the quality of 'fit' between users and an interactive system. This course presents the methodology of gathering suitable data and conducting a CASSM analysis, and show how CASSM can help identify re-design possibilities to improve system utility. CASSM complements established evaluation methods by focusing on conceptual structures rather than procedures. It also provides a guiding framework for analysts working with qualitative data such as think-aloud or interview protocols.
