Rolled Throughput Yield

The probability that a unit will go through a process defect free.

RTY = SUM[ ((Units Produced – Units with Defects) / Units Produced)*100]

Example:

To create the XX, it goes through three processes.

Process A

Process B

Process C

Final Product

Units Produced = 1000

Units with Defects = 100

RTY = 90%

Units Produced = 1000

Units with Defects = 300

RTY = 70%

Units Produced = 1000

Units with Defects = 250

RTY = 75%

Units Produced = 1000

Units Passed QE= 473

RTY = 47%

Out of 1000 units produced only 473 passed without any defects.
