Coordination design (CoorD) is about designing the coordination work. It looks for coordination patterns in work practices, identifies coordinative constructs and tries to identify structures in activities carried out. It describes how to provide elements necessary to produce computer support for coordination work. Coordination design is integrated in a system design process, starts at the same time and ends before implementation. It is interdisciplinary and contains several engineering techniques like requirement analysis or modeling as well as methods from other disciplines like ethnography. It uses coordination rules to describe the temporal and logical order of tasks performed in a cooperative work setting. Coordination design is participatory, contextual, situative, object-oriented, model-driven and rulebased. It consists of several steps: contextual inquiry, task analysis, domain modeling, rule creation and deployment of coordination rules. This paper introduces coordination design and shows its methodology in detail.
