摘要
需求开发是软件生产过程的重要基础。通过分析需求变更、客户与分析员的交流程度以及项目进程压力这三个失信因子与需求文档质量之间相互影响、相互制约的关系,建立反映这种复杂非线性关系的系统动力学模型。利用Vensim软件对模型进行仿真,探讨了失信因子对需求文档质量的影响,为需求管理工作提供了一些参考。
Requirement development is the vital base of software production.Three discredit factors are analyzed the relations of interaction and mutual restriction between them and the quality of required documents,they are the requirement change,communication between the customer and analyzer,and project schedule pressure.Through this a system dynamics model reflecting such complicated non-linear relationship is established.The model is simulated using the software Vensim,the influence of discredit factors on the required document quality is discussed, which provides some references to the requirement management work.
