Rolled Throughput Yield Calculator How Defects In Your Proces The reality of work is that we are all connected. whether it is apparent to us or not there is a link from step a to step z in our processes.when we have def. Rolled throughput yield (rty) is the probability of the entire process producing zero defects. this metric is increasingly relevant when a process has excessive rework. rework is considered the hidden factory costs. a rty measurement has the advantage of showing the losses related to high defect and or rework cases across multiple processes.
Rolled Throughput Yield Rty Lean Strategies International The rolled throughput yield (rty) is calculated by multiplying the first pass yield (fpy) or success rate of each step in a process. the formula for rty is: rty = fpy1 * fpy2 * fpy3 * โฆ. * fpyn. where: rty is the rolled throughput yield. fpy1, fpy2, fpy3, โฆ. fpyn are the first pass yields for each step in the process. By lean sigma corporation. rolled throughput yield (rty) is a process performance measure that provides insight into the cumulative effects of an entire process. rty measures the yield for several process steps and provides the probability that a unit will come through that process defect free. rty allows us to expose the "hidden factory" by. How to use the rolled throughput yield template. for each step in the process, input the number of defects, units produced and opportunities for defects. yield and rolled throughput yield and other metrics will be calculated in the columns to the right. learn more dpmo calculator to calculate dpmo on a single step; cost of quality worksheet. Sigma level calculator. use this sigma calculator to easily calculate process sigma level, defects per million opportunities (dpmo, ppm), yield, rolled throughput yield (rty), percent defects, percent defect units, as well as defects per million units (dpm). various entry combinations are possible, but for full output enter defects, units, and.

The rolled throughput rate is a factor of the first pass yield rates of each step being multiplied together. with this case, 10 steps all with 95% first pass yields rates will be about 60%, which is not as high as you would like. this shows how even 5% of products, when accumulated over many steps, can add up to be a large quantity of rework. First time yield (fty) first time yield, the most common way to calculate process yield, is the probability of a defect free output from a process. this metric considers only the criteria at the end of the process. fty is unit sensitive, meaning it does not take into account whether the output unit is defective, and is calculated by dividing.
