需求描述前的需求跟踪问题

ON THE PRE-RS REQUIREMENTS TRACEABILITY

需求描述前的需求跟踪问题一直是软件工程中非常重要的一个方面，同时又是研究较少的一个方面。需求描述前的需求跟踪的提供者和使用者总存在一些难以解决的矛盾，本文首先从这一角度出发分析了需求描述前的需求跟踪问题。与传统技术一样，面向对象技术也不能保证需求描述前的需求可跟踪性的自动获取，为此文章讨论了在面向对象分析中支持需求描述前的需求跟踪能力的必要条件。在此基础上，文章介绍了一个支持需求跟踪的原型系统（ＯＯＲＴＳＴ）。

Pre-RS requirements traceability is always an important aspect of software engineering on which there are fewer researches.There often exists some conflicts that are difficult to treat between the supplier and the user of pre-RS requirements traceability, of the point from which a discussion on pre-RS requirements traceability is presented.As traditional technology,OOT can't make pre-RS requirements traceability be obtained automatically,of which the requisites for OOA to support pre-RS requirements traceability is discussed.On the basis of the preceding discussions, a prototype system that support requirements traceability is introduced,some further discussions on solving the problem of pre-RS requirements traceability are also presented.
