Scheduled Variance Example Calculation

We will apply our example case to a project that is 10-week scheduled (PV = 10) and is 8-weeks accomplishment already achieved (EV = 8)Using the EVM formula

SV = EV – PV = 8-10 = -2 Weeks

Here shows the schedule variance as -2 weeks, where the planned schedule lacks two weeks compared to the actual schedule.


What is Schedule Variance and how to calculate it?

In the project management realm, a clearly outlined schedule is a prerequisite to success and timebound completion of projects. However, deviations from the planned schedules are not so avoidable in the fast dynamics of project implementation. Schedule variance (SV) is one of the key performance indicators (KPIs) that quantify the scope of the deviation of the real project progress from the planned schedule. In this article we deep dive into the term called schedule variance, examine its role, and present the ways for its estimation.

Understanding Schedule Variance

Schedule Variance (SV) refers to the difference between the planned schedule and the actual outcome recorded at a particular point in time during the project performance. It offers measurements of where the project stands for the schedule, that is, whether the project is ahead of the schedule (positive SV), behind the schedule (negative SV), or precisely in line with the schedule (SV equals zero). Time variances are usually presented by the number of time units (e.g., days, weeks, or months) as the proportion of planned duration....

Calculating Schedule Variance

Different types of schedule variances may be computed by employing different approaches, depending on the desired level of detail and accuracy. The widely used technique is the tracer study in which scientists inject a unique substance with a reduced half-life, later, they measure the amount of the remaining substance for finding the half-life of a process or substance under investigation....
