Besides CP or capability potential, there are several other process capability metrics. They are CPk, Pp, and Ppk. CP, or capability potential, is a measure of the potential capability with the assumption that the distribution of the sample process data is normally distributed and centered within...
The benefits of using Statistical Process Control (SPC) are Continuous Improvements, Increased Process Efficiency (Cpk/Ppk), Quality Cost Reduction including downtime, product interruption, customer complaints or rework, scrap, and Prevention of Quality Issues such as the reduction of overall inspection...
It is expressed with process capability indices of Cp, Pp, Cpk, Ppk, or process sigma. The process capability ratio is an excellent predictor of whether the process will be able to deliver defect-free results. Descriptive Statistics –these are statistics that describe the normal behavior of a...
