During a typical PSO Production Demonstration Run, the goal is to show that the production line is capable of producing parts that meet Chrysler quality and volume requirements. FTC and Yield are equal for a process without repairs so only FTC calculations will be shown in Section I.
Using the three-step, data collection procedure outlined above, the following processed and rejected quantity data were collected during the PDR. The data are shown on the process block diagram.

Begin by calculating the FTC for each operation. Operation 1 is shown here with its respective PSO PDR data
Divide the quantity completed at Operation 1, 270 units, by the Operation 1
quantity attempted at the operation, 300 units. The result is the operation FTC.
