  • CHARACTERISTIC, KEY CONTROL (KCCs): Those process parameters for which variation must be controlled around a target value to ensure that a significant characteristic is maintained at its target value. KCCs require ongoing monitoring per an approved Control Plan and should be considered as candidates for process improvement. (P49 PPAP)

KPCs are established by the customer engineer, quality representative, and supplier personnel from a review of the Design and Process FMEA’s and must be included in the Control Plan. Any KPCs included in customer-released engineering requirements are provided as a starting point and do not affect the supplier’s responsibility to review all aspects of the design, manufacturing process, and customer application and to determine additional KPCs.
