The Digital Cases research project examines how complex information and case management software in professional organizations structures the processing of cases, meaning the handling of patients, the provisioning of social assistance, and the management of legal procedures. The project aims to develop the relationship between organization, technology and profession in a theoretical and conceptual way. Digital Cases engages in a comparison of the structuring effect of case information systems in a hospital, a social services agency, and a court of law, thereby traversing a range of organizational typologies. The project uses an ethnographic approach that centers upon participatory observation and the shadowing of software.
