A Rolled Throughput Yield (YRT) is a percent that measures how many units “roll through” a process, first pass, without defects. This is a measure of internal efficiency where YRT estimates how likely a unit will go from input to output without requiring rework or scrap. YRT is calculated by determining the yield at each process phase, and then multiplying those yields by each other in decimal form. The resulting yield gives a more accurate assessment of internal waste as well as the odds of a customer experiencing an error.
