What is SPI schedule Performance Index?
The schedule performance index (SPI) is a measure of the conformance of actual progress (earned value) to the planned progress: SPI = EV / PV. In both of the above formulas, a value of 1.0 indicates that the project performance is on target.
What does a schedule Performance Index SPI of 0.67 mean?
Schedule Performance Index (SPI**)** = EV / PV = $90,000 / $135,000 = 0.67. This means for every estimated hour of work, the project team is completing only 0.67 hours (approximately 40 minutes).
What does a SPI value of 1 mean?
If the ratio has a value higher than 1 this indicates the project is progressing well against the schedule. If the SPI is 1, then the project is progressing exactly as planned. If the SPI is less than 1 then the project is running behind schedule.
What does a SPI of greater than 1.0 mean?
An SPI greater than 1.0 indicates that more work was completed than was planned. Since the SPI measures all project work, the performance on the critical path also needs to be analyzed to determine whether the project will finish ahead of or behind its planned finish date.
How is SPI calculated?
To calculate your project’s SPI performance, the formula is:
- Schedule Performance Index (SPI) = Earned Value (EV) / Planned Value (PV)
- SPI = EV / PV.
How is SPI calculated p6?
Schedule Performance Index (SPI) measures the physical work accomplished against the amount of work that was planned and is calculated as SPI = Earned Value Cost/Planned Value Cost. Remaining money is calculated as Estimate at Completion (EAC) minus the Actual Cost (AC).
How do you interpret CPI SPI?
If CPI is greater than 1 then project is under budget. If SPI is greater than 1 then project is ahead of schedule. If CPI is equal to 1 then project is on estimated budget. If SPI is equal to 1 then project is on schedule.
What does a schedule Performance Index SPI of 1.365 depict?
What does a schedule performance index (SPI) of 1.365 depict? Schedule performance is better than expected.
What is a schedule of performance?
More Definitions of Performance Schedule Performance Schedule means a schedule or other objective method of determining the achievement of a Performance Goal relative to the applicable Performance Target.
How do you interpret SPI?
Interpretation of Results SPI = 0 means the project work has not started. SPI = 0.5 means the project has performed half the work it was supposed to at this point. SPI = 1.0 means the project is on schedule. SPI = 2.0 means the project has performed twice the work it was supposed to at this point.
How do you calculate cost schedule?
Cost schedule index (CSI) It’s calculated as: Cost Schedule Index (CSI) = Cost Performance Index (CPI) x Schedule Performance Index (SPI) CSI = CPI x SPI.
How do you calculate actual cost?
The actual cost for projects equals direct costs + indirect costs + fixed costs + variable costs + sunken costs. Alternatively, you can use PMI’s simplified formula, which is: actual cost= direct cost + indirect cost.
