To better understand how individuals, groups, and organizations can use information systems more effectively, a research approach closer to the level of social interchange is required. A multiple-level, sustainable, information-technology (IT) learning framework, rooted in patterns of practice and constructed by participatory action research, offers an alternative methodology for investigating sustainable strategies of IT learning. The framework evolved from concrete instances of IT learning across organizational case studies. A patterns-based analysis of the ethnographic data enabled the examination of informal IT learning in community contexts and the identification of IT interventions more likely to produce successful learning outcomes.

Case studies are evocative narrative descriptions of a specific, real-world activity, event, or problem. Case-based learning is well established in professional education (e.g., law, business, medicine) and rapidly expanding in many other disciplines. We use cases as an instructional resource in our own teaching of usability engineering. In this paper, we analyze the proposition that cases can be a minimalist-information design technique-that is, as a design technique that (1) orients information to facilitate user action, (2) anchors information in activity, (3) prevents, mitigates, and leverages error, and (4) develops user autonomy. We discuss the next steps in a research program on case-based learning and speculate on other applications of cases as minimalist information design
