What is CPI and SPI?

By Marie C. On Juin 9, 2022

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 does ACWP stand for? The ACWP (actual cost of work performed) fields show costs incurred for work already done on a task, up to the project status date or today’s date. There are several categories of ACWP fields.

Similarly, 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.

What is the difference between CV and CPI?

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.

Is CPI same as CGPA?

What is SPI CPI CGPA? CPI is the average of SPI of all semesters. CGPA is the average of the last 4 semesters.

What is ACWP formula?

ACWP = Actual Cost of Work Performed is the actual work effort or $ spent to date. BCWP = Budgeted Cost of Work Performed = % Complete x BAC, the value of the work or $ accomplished to date in terms of the baseline schedule, otherwise known as earned value.

What is EAC in project management? In project management, Estimate at Completion (EAC) forecasts the project budget while the project is in progress. Like BAC (Budget at Completion), it is a part of earned value management.

What is the EAC formula? EAC = AC + (BAC – EV) This formula is used when the current deviation with the original estimation is thought to be different in the future. It is generally AC plus the remaining value of the work to perform.

What does SPI 0.75 mean?

SPI is a ratio, which shows you the amount of value you are getting for every day you are working on the project. So an SPI of 0.75 means that for every time unit you are spending on the project, you are getting only 0.75 worth of work done.

What is a good SPI? SPI = EV / PV

If the SPI calculation yields a value that is: Greater than 1: The project is ahead of schedule. Less than 1: The project is behind schedule. Equal to 1: The project is on schedule.

What is BAC in Primavera?

Budget At Completion (BAC)

BAC = BL Budgeted Labour Cost + BL Budgeted Non-Labour Cost + BL Budgeted Material Cost + BL Budgeted Expense Cost.

What is EV and AC? – Earned Value (EV): Also known as Budget Cost of Work Performed (BCWP), the EV can be defined as the quantification of the ‘worth’ of the work done to date. … – Actual Cost (AC): The AC is the executed budget for achieving the work of an ISA action.

How do you calculate CPI and CV?

Grade	Scale	Grade Description
	60.00 – 100.00	First Division/First Class
	50.00 – 59.99	Second Class/Second Division
	30.00 – 49.99	Third Class/Third Division/Pass Class
G		Conceded Pass/Grace Marks

How is CGPA calculated?

Your CGPA is calculated by dividing the sum of the grade points earned by the total credit value of courses you have attempted.

How do you calculate ACWP example? It is calculated from the project budget. For example, if the actual percent complete is 75% and the task budget is $10,000, BCWP = 75% x $10,000 = $7,500.

What are estimated actuals?

An Estimate Actual (EA) is an input value into the Earned Value Management System (EVMS) to measure the direct costs for labour, material, and subcontracted cost for which earned value has been taken but invoices or billings have not entered the accounting system.

What is the actual cost of work performed ACWP )? Actual Cost of Work Performed (ACWP) is the cost incurred and recorded for work completed within a given time period. The ACWP is reported by the contractor’s accounting system in accordance with generally accepted accounting procedures and is simply stated actuals are actuals. ACWP also called Actual Cost.

What is EAC and etc?

In forecasting, the two primary metrics used are estimate to complete (ETC) and estimate at completion (EAC). ETC is the expected cost to finish the remaining work of the project, whereas EAC is the expected total cost of completing all work for the project.

What is a good Tcpi? For all CPI_c 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 do you calculate vac?

VAC is calculated by subtracting the EAC from the BAC. Inturpreting the results is equally simple. If the VAC is a positive integer, that indicates the project is under budget. If the VAC is a negative integer that indicates the project will be over budget.
