A visual language to describe collaborative work

In order to satisfy goals for developing collaboration software, a powerful yet simple visual language has been developed for use by end users in describing plans for work activities. The approach presented is unique because the model allows for collaboration during the planning process; different people are responsible for different parts of the plan. Process plans may be modified on the fly, to allow handling of exceptions and other changes. Policies may be created that automatically create a plan for a user in specific situations. Plans at different levels represent the viewpoint of the people responsible for those plans. These visual representations of plans are then used directly to facilitate the coordination of those activities
