According to the PMBOK®Guide, the schedule performance index (SPI) is a measure of schedule efficiency on a project and is expressed as the ratio of Earned Value (EV) to Planned Value (PV). The Standardized Precipitation Index (SPI; McKee 1993) is the number of standard deviations that observed cumulative precipitation deviates from the climatological Looking for online definition of SPI or what SPI stands for? SPI is typically calculated for timescales of up to 24 months, and the flexibility of the index allows for multiple applications addressing events that affect agriculture, water resources and other sectors. The Formula for the Schedule Performance Index (SPI) SPI - Schedule Performance Index.
For example: A project has a budgeted cost of £120,000. The SPI (McKee and others, 1993, 1995) is a powerful, flexible index that is simple to calculate. It is used to measure how efficiently the project team is using the time on the project. Standardized Precipitation Index (SPI):The SPI is a drought index first developed by T. B. McKee, N.J. Doesken, and J. Kleist and in 1993 (McKee et al. According to PMBOK Guide, the Schedule Performance Index definition is: A measure of schedule efficiency expressed as the ratio of earned value to planned value.. To calculate SPI for any project, find out the Planned Value (PV) and the Earned Value (EV).The formula for calculating the Schedule Performance Index is: .
If EVM is being used only to provide customer reports verifying that the contractor is within acceptable index thresholds (CPI, Dictionary, Encyclopedia and Thesaurus - The Free Dictionary, the webmaster's page for free fun content, An Improved Performance Measurement Approach for Knowledge-Based Companies Using Kalman Filter Forecasting Method, Project performance monitoring methods used in Malaysia and perspectives of introducing EVA as a standard approach/Malaizijoje naudojami projektu efektyvumo stebejimo metodai ir galimybes EVA naudoti kaip standartine metodika, Project management: using earned value analysis (EVA) to monitor a project's progress. The Standardized Precipitation Index (SPI) is a widely used index to characterize meteorological drought on a range of timescales.

According to the PMBOK ® Guide, the schedule performance index (SPI) is a measure of schedule efficiency on a project and is expressed as the ratio of Earned Value (EV) to Planned Value (PV). As a ratio it is calculated by dividing the budgeted cost of work performed, or earned value, by the planned value .
