Post mortem Earned value analysis of a project which is going to be closed showed the following data: SPI: 0.72, CPI: 1.00, What is this telling you?

A. The entire work of the project has been finished behind schedule and on budget. B. The entire work of the project has been finished ahead of schedule and on budget. C. The project has been terminated before completion. At that time it was ahead of schedule and on budget. D. The project has been terminated before completion.

D. The project has been terminated before completion. At that time it was behind schedule and on budget. 

- the cost performance index is 1 which means, the project completed on budget, but the schedule performance index is 0.72 which means the project completed behind schedule. form this we can draft many hypotheses about the project plan, like  if the budge for X time period is enough for X*1.38 time period , the budget plan was more than the actual project budget requirement . Think about this, you have budge B and time schedule 100 months to complete, let’s say one of your expense is employees salary. Now consider ,your schedule is to complete in 100 month and your budget plan must include 100 month salary for employee. According to the give schedule performance index(0.72) your actual project schedule is changed from 100 to 100*1.38 == 138 months. There is no way we can say that the 100 months salary is used to 138 months salary.  This hypothesis tells us that, the project planner budget plan was more than expected. But I will leave the decision of it is good or bad plan for the readers. Because someone can say, wow they did good on contingency  planning, how? Since the plan for contingency was good, they used the contingency to cover 38 months salary. Someone can say, no it’s bad plan, they planned more than expected budget. And more hypothesis

Schedule Performance Index (SPI) and Cost Performance Index (CPI), like variances, allow you to assess the health of a project.

In specific, SPI and CPI help you analyze the efficiency of schedule performance and cost performance of any project.

Schedule Performance Index (SPI)

The Schedule Performance Index indicates how efficiently you are actually progressing compared to the planned project schedule.

As per the PMBOK Guide, “The Schedule Performance Index (SPI) is a measure of schedule efficiency, expressed as the ratio of earned value to planned value.”

The Schedule Performance Index gives you information about the schedule performance of the project. It is the efficiency of the time utilized on the project.

  • f the SPI is greater than one, this means more work has been completed than the planned work. In other words, you are ahead of schedule.
  • If the SPI is less than one, this means less work has been completed than the planned work. In other words, you are behind schedule.
  • If the SPI is equal to one, this means work is being completed at about the same rate as planned, you are on time.

Cost Performance Index (CPI)

The Cost Performance Index helps you analyze the efficiency of the cost utilized by the project. It measures the value of the work completed compared to the actual cost spent on the project.

As per the PMBOK Guide, “The Cost Performance Index (CPI) is a measure of the cost efficiency of budgeted resources, expressed as a ratio of earned value to actual cost.”

The Cost Performance Index specifies how much you are earning for each dollar spent on the project. The Cost Performance Index is an indication of how well the project is remaining on budget.

  • If the CPI is less than one, you are earning less than the amount spent. In other words, you’re over budget.
  • If the CPI is greater than one, you are earning more than the amount spent. In other words, you are under budget.
  • If the CPI is equal to one, this means earning and spending are equal. You can say that you are proceeding exactly as per the planned budget spending, although this rarely happens.

SPI=0.72 presents project is delayed as of data 28%, while cost of the project is on track.
