Question

Quizplus · Accepted Answer

The process capability (C_P) is 1.67. Key Takeaway: A process capability value greater than one implies that the process of three-sigma limit is contained within the client specification. To calculate the C_P, the following equation is used: C_P = (USL - LSL)/ 6? C_P = (0.02 + 0.02)/ 6(0.004) C_P = 1.67
