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.
SPI is a simple interface that allows one chip to communicate with one or more other chips. Let's start with a simple example where only two chips have to communicate together. SPI requires 4 wires to be used in between the two chips. As you can see, the wires are called SCK, MOSI, MISO and SSEL, and one of the chip is called the SPI master, while the other the SPI slave.
