There is a growing trend to develop software that supports the work of groups, as opposed to individuals. Such software is currently being termed groupwure (Tazelaar 1988), and the technical field is being called computer-supported cooperative work (Greif 1988). One aspect of supporting group work involves coordinating the speaking and actions of teams. A coordinator is software which supports team conversations (Winograd 1988). Coordinators are distinguished from traditional software applications because they contain embedded protocols which describe group work (Holt & Cashmau 1981). This position paper presents guidelines for specifying coordinators.
