What is SPI earned value?

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.

How do you find schedule performance index?

To find the schedule performance index, you must first find the planned value and the earned value. SPI is then calculated by dividing this earned value integer by the planned value integer. Therefore, the schedule performance index is a ratio of earned value to planned value.

What is difference between SPI and CPI?

In project performance evaluation Cost Performance Index (CPI) represents the amount of work being completed on a project for every unit of cost spent. On other hand Schedule Performance Index (SPI) represents how close actual work is being completed compared to the schedule.

What is a good CPI and SPI?

SPI is the deviation from the scheduled time for project. If CPI is less than 1 then project is over budget. If SPI is less than 1 then project is behind schedule. If CPI is greater than 1 then project is under budget.

What are schedule performance metrics?

Schedule Metrics refer to a set of verifiable measurement standards by which efficiency, performance, state or quality of a schedule can be identified and assessed. They are used to measure schedules against their baselines to determine any variance and discrepancy.

What if SPI is less than 1?

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.

How are SPI and CPI used in monitoring the project?

CPI is calculated by dividing Earned Value by Actual Cost. CPI is an indicator of how efficiently project resources are performing relative to the project budget. SPI is calculated by dividing Earned Value by Planned Value. SPI measures the performance of resources relative to the project schedule.

What does it mean when CPI is less than 1?

is over budget

If the ratio has a value higher than 1 then it indicates the project is performing well against the 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 CPI less than 1 mean?

is over budget

A CPI of 1 means the project is on budget, which is also a good result. A CPI of less than 1 means the project is over budget. This represents a risk in that the project may run out of money before it is completed.

What is the meaning of an index of 1.00 on SPI?

Schedule Performance Index (SPI) = BCWP/BCWS. This indicates efficiency relative to the plan. If the index is less than 1.00, you are performing less work than you planned. If the SPI is greater than 1.00, you are accomplishing more than planned.

What is a good SPI?

CPI and SPI



When CPI or SPI are greater than 1.0, this indicates better-than-planned project performance, while CPI or SPI less than 1.0 indicates poorer-than-planned project performance.

How do you interpret SPI?

Positive SPI values indicate greater than median precipitation (i.e. wet conditions), and negative values indicate less than median precipitation (i.e. dry conditions). The 1-month SPI is a short-term value and during the growing season can be important for correlation of soil moisture and crop stress.

How is SPI calculated with example?

Using the formula SPI = EV / PV, the project manager will have a value of less than 1 (project behind schedule), of 1 (project on schedule), or greater than 1 (project ahead of schedule). From the resulting SPI calculation, subtract 1 to determine what percent the work is behind or ahead of the planned schedule.

What does a SPI of 1.5 mean?

Answer: If SPI is 1.5, then the contractor is earning more than what he planned. Hence, he is ahead of schedule.

What does a CPI of 0.5 mean?

The CPI = 0.5 value indicates that the project has spent twice the amount that it should have at this point. When the CPI = 1.0, it means that the project is on budget. Meanwhile, if the CPI = 2.0, it means that the project has spent half the amount that it should have at this point.

What does a CPI of .75 mean?

It represents the relative amount that the task is over or under budget. For example, if the task Build Fence has a CPI of 1.25, this would mean that it is 25% under budget. Likewise, a CPI of 0.75 would mean 25% over budget. Greater than 1.0 is the goal.

What is the difference between planned value and earned value?

Planned value provides a baseline measurement of delivery value over time that can be achieved based on the original project plan. Earned value uses the same valuation method but represents the work that is actually completed, or earned.

What is CPI and SPI in GTU?

Full form of SPI / CPI / CGPA. SPI: Semester Percentage Index. CPI: Cumulative Performance Index.

What is the difference between CV and CPI?

Actual cost v Ratio



For cost variance, you get the difference in amount. That is the actual money difference between the earned value and the actual cost. On the other hand, the cost performance index gives you a ratio to work with. This is because you will be dividing the earned value by the actual cost.

What is the purpose of a cost performance index CPI?

Cost performance index (CPI) also known as earned vs. burned, measures the financial effectiveness and efficiency of a project. It represents the amount of completed work for every monetary unit spent.

What does a SPI of 1.5 mean?

Answer: If SPI is 1.5, then the contractor is earning more than what he planned. Hence, he is ahead of schedule.

What is a good cost performance index?

CPI = earned value (EV) / actual cost (AC). A CPI ratio with a value higher than 1 indicates that a project is performing well budget-wise. A CPI value of 1 indicates that a project is performing on budget. A CPI value that is less than 1 indicates that a project is over budget.
