User-Centered Business Process Modeling and Pattern-Based Development for Large Systems

In agile software development, it is imperative for stakeholders such as the users and developers of an information system to collaborate in designing and developing the information system, by sharing their knowledge. Especially in development of a large-scale information system, such collaboration among stakeholders is important, but difficult to achieve. This chapter introduces a modeling method of business processes for requirements analysis and a development framework based on Web-process architectures. The modeling method makes it easier for stakeholders to agree upon requirements. It also employs a formal method to allow business process models to satisfy both understandability and accuracy. On the other hand, the development framework above enables rapid spiral development of short-term cycles through the collaboration of developers and users. This chapter also introduces an example that compares the workloads of two requirement analyses of large-scale system developments for a government service and a financial accounting service, in order to evaluate the advantages of the proposed modeling method.
