 # Quick Answer: What Is A Good SPI?

## 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)..

## What does a CPI of .78 mean?

A Cost Performance Index (CPI) of 0.89 means that the total budget is 89 cents to every financed dollar.

## How does MS Project calculate SPI?

The SPI (schedule performance index) field shows the ratio of the budgeted cost of work performed to the budgeted cost of work scheduled (BCWP/BCWS). … After two days, the budgeted cost of work scheduled (BCWS) is \$50. However, after two days of actual work, 60 percent of the work has been completed, for a cost of \$60.

## What is a good Tcpi?

For all CPIc less than 1.0, the TCPI will be greater than 1.0. 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.

## How can I get SPI in GTU?

SPI = ΣCiGi / ΣCi = 220/30 = 7.33.Similarly CPI (cumulative performance index) will be calculated by same formulae, but for the sum of being over all the courses taken in current and preceding semester. … Class and Distinction etc. will be awarded for the degree on the bases of CPI.

## What does SPI stand for?

Serial Peripheral InterfaceSPI stands for Serial Peripheral Interface—it’s a de facto synchronous communication bus standard.

## How do you interpret Cost Performance Index?

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….Interpretation of ResultsIf CPI is less than 1, the task is over budget.If CPI is one, the task is on budget.If CPI is greater than 1, the task is under budget.

## What if SPI is greater than 1?

The Formula for the Schedule Performance Index (SPI) You have completed more work than planned if the SPI is greater than one; the project is ahead of schedule. … The project is behind schedule. The completed work is equal to the planned work if the SPI is equal to one; the project is on schedule.

## How do you calculate SPI grade?

The SPI will be calculated as follows: SPI = (C1*G1+ C2*G2+ C3*G3+ . . . + Cn*Gn) / (C1+ C2+ C3+ . . . + Cn) where, nis the number of courses registered during the semester, Ciis the number of credits allotted to a particular course, and Gi is the grade points corresponding to the grade awarded for the course.

## What does a CPI of 1.5 mean?

The cost performance index (CPI) is a measure of the financial effectiveness and efficiency of a project. … 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.

## What does a Schedule Performance Index SPI of 0.67 mean?

This means for every \$1 spent, the project is producing only 90 cents in work. 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 is the meaning of an index of 1.00 on SPI?

SPI = 1.00 You’re getting an hour’s worth of work for every hour you put into the project.

## How do you interpret SPI?

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….Interpretation of ResultsIf SPI is less than 1, the task is behind schedule.If SPI is 1, the task is on schedule.If SPI is greater than 1, the task is ahead of schedule.

## Is a high CPI good?

If it’s small, it means that prices more or less stay the same. … All told, an increase in CPI means that a household has to spend more dollars to maintain the same standard of living; that’s mostly bad for the households, but it can be good for businesses and the government.

## What does SPI less than 1 mean?

running behind scheduleIf 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.
