Class 13 Learning Objectives Understand the purpose of workflow management systems and their relationship to business process management Be able to describe in general terms the architecture of a workflow management system Textbook Chapter 1 Before reading the first chapter, you should read the Preface (page v). While this may seem unusual, the preface is a good introduction to the book and the goals it tries to achieve. This course shares some of those goals. Chapter 1 provides an overview of the history of different BPM approaches and positions YAWL within this history as a remedy to the lack of standardization of industry-led approaches to BPM and workflow management. In particular, the chapter suggests that standards efforts may have failed by lack of precise definitions, the interests of software vendors, consultants, and other parties. As a result of this, the workflow pattern initiative was begun to identify sets of recurring patterns in workflow specifications. Originally, these patterns were used to evaluate BPM modeling languages and assess their expressiveness and suitability for modeling these patterns. Subsequently, the YAWL language was developed, based on the mathematical formalism of workflow nets, to directly support these patterns. Workflow patterns in turn take Petri nets as their foundational formalism. The book (not necessarily in this chapter) provides extensive detail on the mathematics of workflow nets and Petri nets.
