Today’s complex sociotechnical systems involve more than just single operators and often include rich team interactions. In this article, the authors explore cognitive work analysis (CWA), a method typically used for deriving design requirements to support single operators, and rework this methodology into a version that is intended to show requirements required to support successful team collaboration. Team-suitable approaches are presented for the first two steps of CWA, work domain analysis and control task analysis. These approaches are collected from past attempts to model teams with CWA and two new teamwork visualizations, collaboration tables and decision wheels. The applicability of the extended models is demonstrated with a health care example.
