A Multi-Perspective Approach for Modeling Workflows

1. Introduction With the recent advance in information technologies, such as the Internet, organisations face, at different levels, several types of challenges. At the external level, organisations have to remain competitive, when offering services to their customers and satisfying these customers' needs. At the internal level, organisations have to be able to react quickly and efficiently to the events that occur, for example the arrival of a new competitor on the market or the development of a new technology. In order to assist organisations, their business processes have to be well defined in order to meet flexibility, adaptability, and scalability requirements. To this end, WF technology seems to be a promising approach to define, enact, and monitor organisations' processes. According to the workflow management coalition, a WF is defined as "the automation of a business process, in whole or part, during which documents, information, or tasks are passed from one participant to another for action, according to a set of procedural rules". WF technology is used in several application domains, eg. manufacturing [1] and healthcare [2].
