The Ratio of Earned Value to Planned Value is called the Schedule Performance Index.
SPI = EV/PV
Planned Value is the authorized budget assigned to the scheduled work to be accomplished for a schedule activity or a work breakdown structure component Earned Value is the value of completed work expressed in terms of the approved budget assigned to that work for a schedule activity or work breakdown structure component.
Schedule performance index (SPI) - Earned value represents the portion of work completed in terms of cost, and planned value represents how much work was planned by this point in time in terms of cost. So, the SPI indicates how the performed work compared to the planned work. This is a measure of the schedule efficiency of a project calculated by dividing earned value (EV) by planned value (PV), as shown in the formula here: SPI = EV / PV
Earned Value Management (EVM)
SPI stands for Schedule Performance Index. SPI is a measure of the schedule efficiency of a project calculated by dividing earned value (EV) by planned value (PV).
The value of a ratio is the total
Spread Ratio: Interest Earned / Interest Expense
Spread Ratio: Interest Earned / Interest Expense
There is not a ratio that has the value of one. A ratio is assets over liabilities.
A labor ratio is the percentage of labor spent vs the amount of revenue earned. A labor ratio is the percentage of labor spent vs the amount of revenue earned.
The value of a ratio - of two numbers - is the value of the first divided by the second.
The difference between the Actual Value & Earned Value is the Project Cost Variance
The ratio of losses paid to premiums earned, usually over a period of one year
