BUSINESS PROCESS MODELING AND WORKFLOW MANAGEMENT

Most of today's approaches to business process engineering (also calle d business process management) start from an activity-centered perspec tive. They describe activities to be carried out within a business pro cess and their relationships, but they usually pay little attention to the objects manipulated within processes. In this article, we discuss an approach to business process modeling, model analysis, and busines s process enaction (also called workflow management) which is based on data modeling, activity modeling, and organization modeling. In fact, the Leu approach to business process management considers data models (describing types of objects to be manipulated in a business process and their relationships), activity models (describing activities to be carried out in a business process), and organization models (describi ng organizational entities involved in a business process) as separate , but equally important, facets of business processes.
