The term process model is used in various contexts. For example, in business process modeling the enterprise process model is often referred to as the ''business process model''. == Overview == Process models are processes of the same nature that are classified together into a model. Thus, a process model is a description of a process at the type level. Since the process model is at the type level, a process is an instantiation of it. The same process model is used repeatedly for the development of many applications and thus, has many instantiations. One possible use of a process model is to prescribe how things must/should/could be done in contrast to the process itself which is really what happens. A process model is roughly an anticipation of what the process will look like. What the process shall be will be determined during actual system development.〔Colette Rolland and Pernici, C. Thanos (1998). ''A Comprehensive View of Process Engineering. Proceedings of the 10th International Conference CAiSE'98''. B. Lecture Notes in Computer Science 1413. Springer.〕 The goals of a process model are to be: *Descriptive * *Track what actually happens during a process * *Take the point of view of an external observer who looks at the way a process has been performed and determines the improvements that must be made to make it perform more effectively or efficiently. *Prescriptive * *Define the desired processes and how they should/could/might be performed. * *Establish rules, guidelines, and behavior patterns which, if followed, would lead to the desired process performance. They can range from strict enforcement to flexible guidance. *Explanatory * *Provide explanations about the rationale of processes. * *Explore and evaluate the several possible courses of action based on rational arguments. * *Establish an explicit link between processes and the requirements that the model needs to fulfill. * *Pre-defines points at which data can be extracted for reporting purposes. 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「Process modeling」の詳細全文を読む スポンサード リンク
