g GE Electromaterials FABRICATION YIELDStep 12: Implement Process Controls

Controls Implemented to Maintain Level

1) Business decision to be made by the Champion (Manufacturing Manager) for any order which CPV will be greater than 1%

2) All loads that have a QC-40 (Dispositioned) are coded at scheduling toensure appropriate financial category for loss

3) All orders that customer is known to pay for the yield loss are removed from the CPV equation (GETEK is biggest pay-off)

4) All orders are tested for patterning regardless of cutting history

5) Implemented weekly Manufacturing Dashboard to ensure process maintains in control.
