Cpkseriously underestimates the total variation if the between subgroup variability is substantial This is illustrated in the Pilot OD example where the lack of stability shown by the out-of-control point on the X chart is evidence of substantial between subgroup variability
Understand how modern quality has evolved from quality control through statistical process control (SPC) to total quality management and leadership principles (including Deming’s 14 points) and other continuous improvement tools including lean six sigma and theory of constraints (Understand) 2 Continuous improvement tools
The purpose of process capability study is to obtain a better understanding of process variation and to quantify how well the process can produce parts fulfilling the requirement Manufacturing process capability study can be done in short-term as well as in long-term
Process capability indices (PCI) are extensively used in industry to evaluate the conformation of products (process yield) to their specifications Conventional univariate process capability indices such as Cp and Cpk are applied to measure performance for single quality characteristic In modern manufacturing when product
Process capability indices measures the ability of process to meet the required engineering specifications the most common capability indices used in the manufacturing industries are CP Cpk Cpm and Cpmk for evaluating the process performance
Cp is a measure of the spread of the process and ignores any mean shifts existing in the process It considers the natural spread of the process and the required specification Cpk measures how centered the data is between specification limits
