What is rolled throughput yield

Learn more about Minitab Throughput yield YTP Throughput yield YTP is the number of good units that are produced divided by the total number of units that go into each step of the process. For example, you have a 3-step process for producing labels. The labels are printed, laminated, then cut. Before we get into calculating Yield, there are a few abbreviations that need to be declared. The Yield of a process step is the success rate of that step or the probability that the process step produces no defects.

In order to calculate Yield we need to know DPU and then we can apply it to the Yield equation above. When reporting numbers that impact financial, investment, operational, and other significant business decisions, it is critical to be honest. Reporting a false reality could lead to investors chipping in on bad investments and other problems.

Instead report accurately and view the honest, negative reports and critical pieces of information that lead to strategizing how to improve. Previous post: Work Sampling. Process 2: There were 46 units that entered Process 2 and none were scrapped but 12 were reworked.

Process 3: There were 46 units that entered Process 3 and 9 were scrapped and none were reworked. At the end of the entire process there are 37 units left of the original 50 units. Once the reworked units are incorporated into the calculation at each step does the RTY become accurate.

This emphasizes the importance of including the reworked units, especially if the rework is very costly or near the cost of scrapping a unit. If the rework cost is very low relative to a scrapped unit then the incorporation of rework figures is reduced in its importance. That does not equate to the correct Rolled Throughput Yield.
