Rolled First Pass Yield (RFPY)

A value based on moving a set of like products through multiple operations with no rework or fixing of defects that occur along the manufacturing process. If no defects are corrected throughout the process the RFPY is usually very low.

As an example, if each process operates at a 'no rework rate' of 90%, and this 90% goes through 5 processes, your RFPY is: 90% x 90% x 90% x 90% x 90% = 59%.
