In 1980, Japan established a process capability index of 1.33 as a general quality standard. What is Process Capability Index (Cpk)? Cpk is a capacity record that tells how well a framework can meet specification limits. Cpk figurings use estimated sigma and, in this way, demonstrates the framework’s “potential” to meet particulars. Capability indices are ratios of the process spread and specification spread.

In simple words, it measures producer’s capability to produce a product within customer’s tolerance range. Process Capability Index is a key concept of Six Sigma. Learn everything you need to know about what is and how to define it. Read This Now! Process Capability Indices: A process capability index uses both the process variability and the process specifications to determine whether the process is "capable" We are often required to compare the output of a stable process with the process specifications and make a statement about how well the process meets specification.

Cpk is one of the common metrics used for measuring process capability. You use it to measure whether your product is within the limits set by the customer. It is known as the ‘Process Capability Index’.

Interpreting Pp, Ppk “Process Performance Index basically tries to verify if the sample that you have generated from the process is capable to meet Customer CTQs (requirements).
