What if 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 mean when CPI is less than 1?

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

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.

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.

What is the 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 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.

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.

How do you calculate EV and PV?

Calculating earned value

Earned value calculations require the following: Planned Value (PV) = the budgeted amount through the current reporting period. Actual Cost (AC) = actual costs to date. Earned Value (EV) = total project budget multiplied by the % of project completion.

Can earned value be negative?

Earned value and negative float is a condition in the schedule that indicates the project will be unable to meet one or more of its objectives. It should not be ignored, or worse, marginalized with slap-dash tricks to get rid of it such as deleting relationships or reducing durations to zero.

What is SPI and CPI result?

Engineering Result will declare in point of SPI(Semester Performance Index), CPI(Cumulative Performance Index) and CGPA(Cumulative Grade Point Average). Especially in GTU Evaluation System SPI,CPI and CGPA are so much Important for Placement and for other Important Criteria.

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 Results

  1. If CPI is less than 1, the task is over budget.
  2. If CPI is one, the task is on budget.
  3. If CPI is greater than 1, the task is under budget.

How is SPI calculated in MS Project?

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.

How is EAC calculated?

EAC Calculation Categories

  1. EAC = AC + Bottom-up ETC. This formula is used when the original estimation is fundamentally flawed. …
  2. EAC =BAC/Cumulative CPI. This formula is used when the original estimation is met without any deviation. …
  3. EAC = AC + (BAC — EV) …
  4. EAC = AC + [BAC — EV / (Cumulative CPI x Cumulative SPI)]

How is Earned Value calculated?

Earned value can be computed this way : Eearned Value = Percent complete (actual) x Task Budget. For example, if the actual percent complete is 50% and the task budget is $10,000 then the earned value of the project is $5,000, 50% of the budget provided for this project.
