Midway through a US$1 million project, the project manager conducts an earned value analysis (EVA). The analysis shows a planned value (PV) of US$623,000, an earned value (EV) of US$523,000, and an actual cost (AC) of US$643,000. Based on these numbers, what is the project’s cost variance (CV) and schedule variance (SV)? 在一个价值100万美元的项目中途,项目经理进行挣值分析(EVA),分析显示计划价值(PV)为623,000美元,挣值(EV)为523,000美元,实际成本(AC)为643,000美元。根据这些数字,项目的成本偏差(CV)和进度偏差(SV)分别是多少? ◑A.CV=+US$120,000, and SV=+US$100,000CV=+120.000美元,SV=+100,000美元 ◑B.CV=+US$100,000, and SV=+US$120,000CV=+100.000美元,SV=+120,000美元 ◑C.CV=-US$100,000, and SV=-US$120,000CV=-100.000美元,SV=-120,000美元 ◑D.CV=-US$120,000, and SV=-US$100,000CV=-120.000美元,SV=-100,000美元
