摘要
在软件需求获取阶段,涉众可能会不断更改他们的需求甚至提出新的需求。针对软件需求不断变更的问题提出了一种基于场景元模型的解决方法。该方法利用场景元模型中定义的元素及其关系建立需求中的可追踪性,通过计算变化追踪矩阵查找需求变更时影响的其他因素,最后验证了所建立追踪关系的正确性。通过场景元模型的方法在需求的各个元素之间建立可追踪关系,可准确找到需求变更时波及到的其他元素,提高捕获需求的效率和准确性。
In software requirements elicitation phase, stakeholders may change their needs continuouslyandnew requirements emerge frequently. To solve the problem of ever-changing software requirements, a scenariometa-model based method is proposed. By means of establishing traceability in requirements accordingto the elements and their relationships which defined in the scenario meta-model, and calculating thechange trace matrix to find the impact elements when requirements changed. Finally, verify the correctnessof the tracking relation. The scenario meta-model method can build traceability relationships among the elementsin requirements,find relevant elements accurately when requirement changes, and improve the efficiencyand accuracy when capture requirements.
