Process Capability Index, Cpk. Cpk is a short term process index that numerically describes the "within subgroup" or "potential" capability (Ppk is a long term indicator) of a process assuming it was analyzed and stays "in control". The …
· [Potential] Process Capability Analysis (Cp, Cpk): A process capability study uses data from a sample to PREDICT the ability of a manufacturing process to produce parts conforming to specifications. This prediction enables us to "qualify" a new manufacturing process as being fit for use in production.
· A process capability index is a numerical summary that compares the behavior of a product or process characteristic to engineering specifications. These measures are also often called capability or performance indices or ratios; we use capability index as the generic term. A
Process capability uses the process sigma value determined from either the Moving Range, Range or Sigma control charts. Pp and PPk are used for Process Performance. Generally you use this when a process is too new to determine …
· Process capability compares the output of an in-control process to the specification limits by using capability indices.The comparison is made by forming the ratio of the spread between the process specifications (the …

· Process capability study is a scientific and a systematic procedure that uses control charts to detect and eliminate the unnatural causes of variation until a state of statistical control is reached. When the study is completed, you will identify the natural variability of the
· Process capability measure – Cpk Cpk is a measure called the capability index. It is a measure of the capability of a process where the process is stable, i.e. we exclude any special, once off, unusual causes of variation, but do include routine common causes of variation. The Cpk measure varies from 1 to 2 as follows: Cpk < 1.00 Process is ...
Process Capability (Cp) is a statistical measurement of a process's ability to produce parts within specified limits on a consistent basis. To determine how our process is operating, we can calculate Cp (Process Capability), Cpk (Process Capability Index), or Pp (Preliminary Process Capability) and Ppk (Preliminary Process Capability Index ...
Process Capability – Cp, Cpk, Pp, Ppk. Process Capability is a relatively simple statistical measure which provides an estimate on the level of process outputs which will be within permitted specification limits. It provides a comparison between the …

· Process Capability has two parts namely, the process and its capability, which essentially means how capable is the process of satisfying the customer or whether the process is capable enough. Talking about the process, it is often …
· Process Capability Studies [The following is based in part on the paper "Process Capability Studies" prepared by M. Suozzi, Member of the Technical Staff, Hughes Aircraft Company, Tucson, Arizona, 27NOV90] Introduction Process capability is an important concept for industrial managers to understand. The
The process capability index is defined as the quotient between the length of the acceptance interval and six times the standard deviation obtained as a result of the design and production processes (Taguchi, Elsayed and Hsiang, 1989 ). The response should be made dimensionless by using the variables defined in (3.13).
