一个计划以迭代方式来进行执行阶段的项目,在前三个迭代中有以下度量指标。迭代进度绩效指数为1.2,0.98,0.90;成本绩效指数为1.15,1.0,0.98;项目的需求之一是,为了获得项目的付款授权,SPl和CPl都不能低于0.95。项目经理在迭代4中应该做什么来确保项目符合需求?A project that plans to execute in an iterative manner has the following metrics in the first three iterations. The iteration progress performance index is 1.2, 0.98, 0.90; The cost performance index is 1.15, 1.0, 0.98; One of the requirements of the project is that in order to obtain payment authorization for the project, both SPL and CPl cannot be lower than 0.95. What should the project manager do in iteration 4 to ensure that the project meets the requirements?
A.进度赶工Schedule crashing
B.快速跟进Fast tracking
C.挣得进度Earned schedule
D.挣值Earned value
参考答案:A
解析:根据题干可以得知,第三次迭代时,SPI已经低于0.95,进度延迟,需要进度压缩。进度压缩一般两种方式:赶工或者快速跟进,根据题干,当CPI>0.95可以赶工;否则快速跟进。当前CPI=0.98,即CPI还是安全的,可以通过增加成本实现赶工。选项B错误,快速跟进的代价是返工风险,如果可以赶工,就不要快速跟进。选项C错误,挣得进度是挣值管理的一个扩展,能够测量项目进度和预测项目完成时间,不是进度压缩的解决方案。选项D错误,挣值只是反映成本绩效及进度绩效的信息,不是解决方案。
