CAPM Practice: Demonstrate an understanding of a project management plan schedule

Schedule Variance = EV - PV. A positive SV means more work was accomplished than planned (ahead of schedule). A negative SV means less work was accomplished than planned (behind schedule). SV measures the schedule deviation in monetary terms (value of work done vs. value of work planned).

**Why not A:** AC - PV calculates neither a standard earned value metric nor a meaningful variance. This formula does not correspond to any recognized EVM calculation. Schedule Variance uses EV and PV, while Cost Variance uses EV and AC.

**Why not B:** EV - AC is the formula for Cost Variance (CV), not Schedule Variance. Cost Variance measures whether the project is over or under budget, while Schedule Variance measures whether it is ahead of or behind schedule. They use different baseline comparisons.

**Why not D:** BAC - EV does not calculate Schedule Variance. This formula represents the remaining work value (the difference between total budget and work completed so far), which is not a standard named EVM metric. Schedule Variance is specifically EV - PV.
