基于本质用例的软件需求分析和获取

Essential Use Case Based Software Requirements Analysis and Elicitation

本质用例描述了用户与系统间抽象、轻量级和技术无关的对话过程。与传统的用例相比,本质用例更为简洁,避免了在开发过程早期就进行设计决策。本文探讨了在软件系统开发过程中,使用本质用例进行需求分析与获取的过程,并将其与传统的用例技术进行了比较。

Essential use cases are abstract, lightweight, technology-free dialogues between user and system. Compared with conventional use cases, the steps of essential use cases are more concise. The benefit of this abstraction is that no particular design decision needs to be made at the early stage of system development. This paper discusses an ap- proach of software requirements analysis and elicitation based on essential use case, and compares it with the conven- tional use case technology.
