某系统集成项目包含了三个软件模块,现在估算项目成本时,项目经理考虑到其中的模块 A技术成熟,已在以前类似项目中多次使用并成功支付,所有项目经理忽略了 A 的开发成本,只给 A 预留了 5 万元,以防意外发生。然后估算了 B 的成本为 50 万元,C 成本为 30 万元,应急储备为 10 万元,三者集成成本为 5 万元,并预留了项目的 10 万元管理储备。如果你是项目组成员,项目开始执行后,当项目的进度绩效指数 SPI 为 0.6 时,项目实际花费为 70 万元,超出预算 10万元,如果不加以纠偏,请根据当前项目进展,估算该项目的完工估算值(EAC)为( )万元
- A.64
- B.134
- C.194.4
- D.124.4
正确答案及解析
正确答案
解析
项目的成本基准不包括任何的管理储备,而在项目的总体预算中需要加上管理储备,因此成本基准为100万元,总预算是110万元。
项目实际花费AC为70万元,超出预算 10万元,因此PV为60万元,SPI=EV/PV=0.6,算得EV为36万元。 项目未来不加以纠偏,属于典型偏差,EAC=ETC+AC=(BAC-EV)/cpi+AC=(100-36)*70/36+70=194.4万元。
