PMI-SP Exam - Topic 8 Question 112 Discussion
Topic #: 8
You work as a Project Manager for Tech Perfect Inc. Several projects are running under your supervision. Martha, the team leader of a project, provides you performance indexes of her project. The cost variance (CV) of her project is -20. What does this figure depict?
According to the question, the cost variance of the project is -20, which is a negative
figure. The negative CV depicts that the costs are higher
than planned.
What is CV?
Cost variance (CV) is a measure of cost performance on a project. The variance notifies if costs are
higher than budgeted
or lower than budgeted. The cost variance is calculated based on the following formula:
CV = Earned Value (EV) - Actual Cost (AC)
A positive value means that spending is less than budgeted, whereas a negative value indicates that
costs are higher than
originally planned for the project.
Answer option B is incorrect. This result is drawn when the CV value is positive.
Answer option A is incorrect. If the CV is zero, it shows that spending is right on target.
Answer option C is incorrect. This result is depicted by viewing the schedule variance (SV), not the
CV.
What is SV?
Schedule variance (SV) is a measure of schedule performance on a project. The variance notifies that
the schedule is ahead
or behind what was planned for this period in time. The schedule variance is calculated based on the
following formula:
SV = Earned Value (EV) - Planned Value (PV)
If the resulting schedule is negative, it indicates that the project is behind schedule. A value greater
than 0 shows that the
project is ahead of the planned schedule. A value of 0 indicates that the project is right on target.
