1. add one column "Test operation", for each module in the list, then we can identify the yield under different test station. Otherwise we don't know the yield belongs to which station.
2. within Chart of FPY, also need to add test operation for each Bar of module. I circled the yield by product below, part number, appeared 5 times, if info of test operation is appeared together with part number, that could be readable much easier.
