Complexity model for business process analysis

Business processes are the combination of human activities, information technology, and organizations. The emergence of radio frequency identification (RFID), and web services enable innovation in business processes, but the combination of multiple functions potentially increases their complexity. Studies show successful business process deployment starts with a thorough understanding of the business process model. In this paper, process complexity metrics is to evaluate the understandability, clarity, and correctness in the business process. A patternbased complexity metric which combines software science and graph theory is developed. An example from cutting tool supply chain is used to illustrate the concept and models.
