What do you do when SPI is less than 1?
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 it indicate when SPI is less than 1?
Schedule performance index (SPI) is a ratio of the earned value (EV) to the planned value (PV). If the SPI is less than one, it indicates that the project is potentially behind schedule to-date whereas an SPI greater than one, indicates the project is running ahead of schedule.
What does it mean when CPI is less than 1?
is over budget
A CPI of 1 means that the project is performing on budget. A CPI of less than 1 means that the project is over budget.
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.
What does SPI and CPI mean?
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 is the difference between SV and SPI?
Both schedule variance (SV), also an EVM calculation, and SPI measure whether a project is behind, on, or ahead of schedule. SV gauges how much the actual work is deviating from the planned schedule, while SPI is the ratio of the performed work to the scheduled work.
What does a CPI of 0 mean?
CPI = 0 means the project work has not started. CPI = 0.5 means the project has spent twice the amount that it should have at this point. CPI = 1.0 means the project is on budget. CPI = 2.0 means the project has spent half the amount that it should have at this point.
What does a positive CPI mean?
CPI stands for consumer price index, an average of several consumer goods and services that are used to give an indication of inflation. Movements in CPI are usually given in percentages, with positive movements signifying inflation and drops signifying deflation.
What does Tcpi greater than 1 mean?
When TCPI turns out to be greater than one (> 1.0), a more normal case for BAC calculations, the value of the remaining project work must be executed at a better cost performance level than the project’s completed work.
What is a good SPI?
As with the CPI, SPI values under 1 are not good because they mean the project is behind schedule. A value of 1 means the project is on schedule, and a value more than 1 means the project is ahead of schedule.
What does SPI over 1 mean for a project?
1 Answer. SPI over 1 means that your project is ahead of schedule, which is a good thing. So this means that most likely there is something wrong in your calculation. One question, how do you know that your project is behind schedule although the main metric (SPI) is pointing that it’s ahead of schedule.
How to calculate the Schedule Performance Index ( SPI )?
The Formula for the Schedule Performance Index (SPI) You can find the Schedule Performance Index by dividing Earned Value by Planned Value. Schedule Performance Index = (Earned Value) / (Planned Value) SPI= EV / PV
Is it a good thing to have a SPI over 1?
I don’t understand how is this possible… I’m sure I’m doing the calculation correctly – could it be that I have misunderstood the concept and an SPI over 1 is actually a bad thing and not a good thing? (it’s my first project!) SPI over 1 means that your project is ahead of schedule, which is a good thing.
How to know that your project is behind schedule?
One question, how do you know that your project is behind schedule although the main metric (SPI) is pointing that it’s ahead of schedule. In other words, which metric, other than SPI, are you using to measure the performance of your project?
