Earned Value management (PV, AC, EV, ETC, CV, SV, CPI, SP)

Budgeted cost of planned work PV or bcws= plan workload * Budget quota

Actual cost of completed work AC or ACWP

Budgeted cost of completed work EV or bcwp= completed work * Budget quota

Progress deviation (SV) =ev-pv,sv>0 Progress sv<0 Progress lag

Cost Variance (CV) =ev-ac,cv>0 cost savings cv<0 cost overruns

Cost performance Index (CPI) =ev/ac,cpi>1 represents cost savings cpi<1 cost overruns

Progress Performance Index (SPI) =ev/pv,spi>1 indicates progress ahead spi<1 progress lag

BAC (Budget cost at completion) Baseline budget costs: All work budgets, without changing cost benchmarks, BAC will not change

etc (estimated to Complete) completion fashion cost estimate: To complete, the remaining workload still need how much cost, etc is to estimate the remaining work cost of complete project

etc= Total pv-completed Ev=bac-ev

The pv*cpi of etc= remaining work

EAC (estimate at completion) estimates the total cost of the project based on the project's performance and risk. The most commonly used prediction techniques are the different forms of the following methods:

1, eac= up to the current actual cost plus all the remaining work of the new estimates. This method is usually used in two situations ① past implementation indicates that the original estimate assumption is completely outdated, ② the original estimate is no longer applicable because of the change of condition. Formula: Eac=ac+etc

2, eac= to the current actual cost plus the remaining budget (Bac-ev). The current deviation is considered a special case, and the project team often uses this approach in the belief that similar deviations will not occur in the future. Formula: Eac=ac+bac-ev.

3. eac= the current actual cost plus the budget of the remaining items modified by the actual Cost performance index (CPI). This method usually treats the current deviation as a typical form for future deviations. Formula eac=ac+ (Bac-ev)/CPI, where the CPI is the cumulative CPI.
