1. Introduction 1.1. Background Work Flow Management is a fast evolving technology which is increasingly being exploited by businesses in a variety of industries. Its primary characteristic is the automation of processes involving combinations of human and machine-based activities, particularly those involving interaction with IT applications and tools. Although its most prevalent use is within the office environment in staff intensive operations such as insurance, banking, legal and general administration, etc, it is also applicable to some classes of industrial and manufacturing applications . Many software vendors have WFM products available today which involve WFM technology and there is a continual introduction of more products into the market. The availability of a wide range of products within the market has allowed individual product vendors to focus on particular functional capabilities and users have adopted particular products to meet specific application needs. However, there are, as yet, no standards defined to enable different WFM products to work together, which is resulting in incompatible "islands" of process automation. The WFM Coalition is a grouping of companies who have joined together to address the above situation. It has been recognised that all work flow management products have some common characteristics, enabling them potentially to achieve a level of interoperability through the use of common standards for various functions. The WFM Coalition has been established to identify these functional areas and develop appropriate specifications for implementation in workflow products. It is intended that such specifications will enable interoperability between heterogeneous workflow products and improved integration of workflow applications with other IT services such as electronic mail and document management, thereby improving the opportunities for the effective use of workflow technology within the IT market, to the benefit of both vendors and users of such technology. 1.2. Purpose The purpose of this document is to provide a framework to support the development of the various specifications described above. It provides a common "Reference Model" for workflow management systems identifying their characteristics, terminology and components, enabling the individual specifications to be developed within the context of an overall model for workflow systems. The detailed specifications will be developed as separate documents. 1.3. Scope This document covers the concepts, terminology, general structure of a workflow management system, its major functional components and the interfaces and information interchange flows between them. It identifies the areas appropriate for standardisation and illustrates the potential interoperability scenarios which may be supported through the use of common standards. It also discusses, where appropriate, the applicability of existing standards to workflow management systems and their integration with other standard IT services. It does not cover wider aspects of business process engineering which lie outside the use of information technology to support the business process.
