The need for workflow management is apparent from the recent increase in the number of products (Lotus Note, SAP Business Workflow, Workmanager) that aim to support various business workflow features. However, a conceptual modeling or specification of workflow is paramount if workflows are to be managed. The authors propose using two distinct constructs to model workflow, the transaction and the task. The transaction deals with the specification of the communication aspects of workflow, while the task deals with the required adaptability of workflow systems. They demonstrate conceptual modeling of workflow using a real-life system in a hospital.
