Policies & Procedures: Continuous Process Improvement

clear gif

TI uses the Process Capability Index (Cp and Cpk) as a tool to drive continuous improvement activities for critical in-line process and electrical parameters.
 
 

The goal for Cpk has recently been changed to 1.67 to align with the TS 16949 specification. Parameters with Cpk values below 1.67 are targeted for continuous improvement programs.
 
 

Process Capability reports trend Cpk values over a rolling 12 month period. The pareto principle is used to prioritize continuous improvement programs appropriately.
