A culvert replacement under a county road has both schedule variance and cost variance figures in the monthly report. Why review them together?
Select an answer to reveal the explanation.
Short Explanation
Looking at schedule variance and cost variance side by side is like checking both the clock and the budget on the culvert—either one alone can lie about overall health. Together they sketch time and money versus the plan.
Full Explanation
SV addresses schedule performance versus planned progress; CV addresses cost performance versus earned work. Reviewing both prevents one-dimensional status calls. Neither variance replaces authorized scope or other baselines; they inform control decisions against the plan.
