Abstract: This paper proposes a risk driven project buffer allocation method which will allocate project buffer
according to risks, schedule constrains and resource constrains between tasks. The result of simulation based
experiments shows pared with Critical Chain, the proposed method can remarkably reduce the frequency of
plan change and minimize the negative impact to project duration. The method and the tool can help project
managers to decide appropriate project buffer length and make better use of the limited buffer. The stability and
trustworthiness of project plan schedule can be enhanced.
Key words: software project management; plan change; risk; project buffer; process simulation; resource
constrain
摘要: 提出一种风险驱动的项目缓冲分配方法,
通过综合考虑软件项目的风险因素、
结果表明,在风险较高的软件开发项目中,该方法相对于关键链项目管理中尾部集中的项目缓冲分配方法,可确保在
对项目平均执行工期产生较小影响的同时,
工具可以帮助软件项目经理确定合适的项目缓冲时间长度以及缓冲分配方案,进而提高软件项目计划的可信性和
执行的稳定性.
