Information System Development by Business Process Modeling Based on Adaptability to Specification Changes

摘要

Business modeling has been attracting attention in the development of information systems to be used for analyzing and designing the working procedures of the system under development. In this paper, we propose a method of information system development by business process modeling based on adaptability to specification changes. The proposed method builds a business process model from the requirement specifications, translates the model into UML, identifies the elements bridging the translation from Business Process Modeling to UML, that is, the analytical stage and the design stage, and seeks to perform both processes continuously while finalizing the design. The proposed method was applied to the prototyping of a bus booking and management system, comparing the results using only UML for the configuration with those obtained by using the proposed method. The proposed method proved effective in the early detection and removal of bottlenecks, in accurate modeling, and in adjusting to changes in the specifications.
