本考题考查的知识点为成本绩效指数。出自《信息系统项目管理师教程》第八章项目成本管理8.4.2成本控制的工具和技术,全书第163页。
成本绩效指数(CostPerformanceIndex,CPI)(CPI=EV/AC)。CPI>1.0表示成本节余,实际成本少于计划成本,资金使用效率较高;CPI<1.0表示成本超支,实际成本多于计划成本,资金使用效率较低。
实际成本(ActualCost,AC),是在规定时间内,完成活动内工作实际发生的成本总额。AC即到某一时点已完成的工作所实际花费或消耗的成本。
挣值(EarnedValue,EV),是实际完成工作的预算价值。该值描述的是根据批准认可的预算,到某一时点已经完成的工作应当投入的资金。
