Schedule variance is an indicator of whether a project schedule is ahead or behind. It is typically used within earned value management (EVM) to provide a progress update for project managers at the point of analysis.

How do you calculate schedule variance?
Schedule Variance can be calculated by subtracting the Budgeted Cost of Work Scheduled (BCWS) from the Budgeted Cost of Work Performed (BCWP). BCWP measures the cost of actual work done.
SV Formula
- SV = Schedule Variance.
- EV = Earned Value.
- PV = Planned Value.
What is schedule variance and cost variance?
Schedule variance shows the deviation in time consumed and the estimated time. Cost variance is the difference of earned value and actual cost. Schedule variance is the difference of earned value and planned value. CV = EV – AC. SV = EV – PV.
Why is schedule variance important?
As a means of judging a project’s progress and how well the initial project plan is being adhered to, Schedule Variance is one of the most useful and common metrics used. It can give quick insight into how well the project has performed so far and whether it is ahead of schedule or behind it.
What does variance mean in project management?
Variance is the amount of change from the original plan. In the project management context, a variance can be a problem or risk, with an impact on the schedule and budget. Calculating “Variance at Completion” (VAC) is a way for project managers to forecast cost variance (CV) at the end of the project.
What is schedule variance and effort variance?
Schedule Variance: Any difference between the scheduled completion of an activity and the actual completion is known as Schedule Variance.Effort Variance: Difference between the planned outlined effort and the effort required to actually undertake the task is called Effort variance.
What is the difference between SV and CV?
– Cost Variance (CV): The CV is the difference between the earned value of the work performed and the executed budget (Actual Cost).- Schedule Variance (SV): The SV is the difference between the earned value of the work performed and the planned value of the work scheduled.
What is the schedule variance and what do you infer?
The Schedule Variance (SV) is the difference between the earned value of work performed and the work scheduled. SV tells you the value of work performed less value of work scheduled.
What is CPI and SPI?
The Cost Performance Index (CPI) is defined as the ratio of Earned Value to Actual Cost, while the Schedule Performance Index (SPI) is defined as the ratio of cumulative Earned Value to cumulative Planned Value (PMI, 2000). Both CPI and SPI are traditionally defined in terms of the cumulative values.
What does it mean if CV is positive and SV is negative?
SV is positive and CV is negative: The project is ahead of schedule but over budget. In other words, more tasks have been performed than were scheduled at this point, but the tasks that have been performed are over budget. SV is negative and CV is positive: The project is under budget but behind schedule.
What is CV and SV in project management?
Cost Variance (CV): This is the completed work cost when compared to the planned cost.Schedule Variance (SV): This is the completed work when compared to the planned schedule. Schedule Variance is computed by calculating the difference between the earned value and the planned value, i.e. EV – PV.
What does EV mean in project management?
Earned value
Earned value (EV) is a way to measure and monitor the level of work completed on a project against the plan. Simply put, it’s a quick way to tell if you’re behind schedule or over budget on your project.
Why is schedule variance in dollars?
Wrike reports that schedule variance is the budgeted cost of work performed minus the budgeted cost of work scheduled. In other words, it is the dollar value of the difference between the work scheduled for completion in a specified period and the work actually completed.
How schedule variances to the schedule baseline are identified?
In project management, variance baseline is established by identifying the cost, schedule and scope. Scope defines all the work which needs to be done.A positive variance means the project is going on ahead of schedule or is under the cost. A negative variance means the project is late or over the cost.
What does a schedule variance of 0 mean?
If you calculate schedule variance and the value is zero, you are on schedule. Schedule variance is zero at the completion of a project because all of the planned value has been earned. Planned value (PV) is the scheduled cost of work that will be performed in a specific timeframe.
What is the EAC formula?
Estimate at completion (EAC) is calculated as budget at completion divided by cost performance index. Formula 1 for EAC is as follows: Estimate at completion (EAC) = Budget at completion (BAC) / Cost performance index (CPI)
What is meant by effort variance?
Effort variance (EV) calculates variance of actual effort versus planned effort. The formula for effort variance is:Effort variance = [(Actual effort – Planned Effort)/Planned effort] * 100The effort variance may be greater than expected. For example, we estimated 100 hours but actual work took 110 hours.
How do you calculate CPI from PMP?
Using the formula CPI = EV / AC, the project manager will have a value of less than 1 (project over budget), of 1 (project on budget), or greater than 1 (project under budget). CPI in project management measures the cost efficiency of a project.
Is Positive schedule variance good?
A negative schedule variance (SV < 0) indicates that the project is behind the schedule, as earned value does not meet the planned value. A positive schedule variance (SV > 0) indicates that the earned value exceeds the planned value in the reference period(s), i.e. the project is ahead of the schedule.
What is the cost variance CV )?
Cost variance (CV), also known as budget variance, is the difference between the actual cost and the budgeted cost, or what you expected to spend versus what you actually spent.
What are three pieces of information that should be included in the cost and schedule variance explanations?
The client is asking for information on the cost incurred to date, work completed, and how the project is performing in terms of cost and schedule. You will get this information with the help of Earned Value Management. Earned Value Management has three basic elements: Earned Value, Planned Value, and Actual Cost.
