IDEF3 or Integrated DEFinition for Process Description Capture Method is a business process modelling method complementary to IDEF0.〔Richard J. Mayer et al. (1993) (Information Integration for Concurrent Engineering (IICE): IDEF3 Process Description Capture Method Report ). Logistics Research Division, Wright-Patterson AFB, OH 45433〕 The IDEF3 method is a scenario-driven process flow description capture method intended to capture the knowledge about how a particular system works.〔Patricia Griffith Friel and Thomas M. Blinn (1989). ("Automated IDEF3 and IDEF4 Systems Design Specification Document" ). Technical report. NASA Johnson Space Center.〕 The IDEF3 method provides modes to represent both〔 * Process Flow Descriptions to capture the relationships between actions within the context of a specific scenario, and * Object State Transition to capture the description of the allowable states and conditions. This method is part of the IDEF family of modeling languages in the field of systems and software engineering. == Overview == One of the primary mechanisms used for descriptions of the world is relating a story in terms of an ordered sequence of events or activities. The IDEF3 Process Description Capture Method was created to capture descriptions of sequences of activities, which is considered the common mechanisms to describe a situation or process. The primary goal of IDEF3 is to provide a structured method by which a domain expert can express knowledge about the operation of a particular system or organization. Knowledge acquisition is enabled by direct capture of assertions about real-world processes and events in a form that is most natural for capture. IDEF3 supports this kind of knowledge acquisition by providing a reliable and wellstructured approach for process knowledge acquisition, and an expressively, yet easy-to-use, language for information capture and expression.〔 Motives for the development of IDEF3 were the need:〔 * to speed up the process of business systems modeling, * to provides mechanisms to describe this data life cycle information, * to supported project management techniques by an automated tool, * to provide the concepts, syntax, and procedures for building system requirements descriptions, and * to work well both independently and jointly with other methods which address different areas of concentration (e.g., the IDEF0 Function Modeling method) as a complementary addition to the IDEF method family. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「IDEF3」の詳細全文を読む スポンサード リンク
