What is the definition of schedule variance?

The correct answer is B. A measure of schedule performance between the earned value (EV) and the planned value (PV). Schedule Variance (SV) = EV − PV. It measures how much ahead or behind schedule the project is by comparing the value of work actually completed (EV) to the value of work that was planned to be completed (PV) at a given point in time. A positive SV means ahead of schedule…

Question

What is the definition of schedule variance?

Options

AA measure of the cost variation magnitude to the original cost baseline
BA measure of schedule performance between the earned value (EV) and the planned value (PV)
CThe amount of budget deficit, expressed as the difference between earned value (EV) and the actual cost (AC)
DA measure of schedule efficiency expressed as the ratio of earned value (EV) to planned value (PV)

Explanation

Schedule Variance (SV) = EV − PV. It measures how much ahead or behind schedule the project is by comparing the value of work actually completed (EV) to the value of work that was planned to be completed (PV) at a given point in time. A positive SV means ahead of schedule; negative means behind. Option A describes cost variance magnitude. Option C describes cost variance (CV = EV − AC), which measures budget performance, not schedule. Option D describes the Schedule Performance Index (SPI = EV/PV), which is a ratio expressing schedule efficiency-distinct from variance, which is an absolute difference.
