In 1992 his co-authored book Object-Oriented Software Engineering - A Use Case Driven Approach helped to popularize the technique for capturing functional requirements, especially in software development. However, this definition is too generic to describe the purpose, as other four diagrams (activity, sequence, collaboration, and Statechart) also have the same purpose. For example, activity diagrams, a type of UML diagram, can be used as a replacement for flowcharts. Flow of Events is a critical element of any use case description. A use case is a software and system engineering term that describes how a user uses a system to accomplish a particular goal. Download 11.89 KB #28. In other words, a use case describes “who” can do “what” with the system in question.
