Definition [Suggest Change]. The Schedule Performance Index (SPI) is computed by dividing the Budget Cost for Work Performed (BCWP) by the Budgeted Cost for Work Scheduled (BCWS). This metric is an EVM performance factor representing schedule efficiency.
Sometimes SPI is called a four-wire serial bus, contrasting with three-, two-, and one-wire serial buses. The SPI may be accurately described as a synchronous serial interface, but it is different from the Synchronous Serial Interface (SSI) protocol, which is also a
