Process Capability Index (Cpk) - What is Six Sigma

WebbA capability analysis is based on a sample of data taken from a process and usually produces: 1. An estimate of the DPMO (defects per million opportunities). 2. One or more capability indices. 3. An estimate of the Sigma Quality Level at which the process operates. STATGRAPHICS provides capability analyses for the following cases: WebbAbstract: In the paper , a process capability and process performance analyse s for continuous and attribute data are conducted by using an industry example. The inner diameter of the bearing rings is analysed by applying the normal capability analysis for the continuous data and byapplying the binomial capability analysis for the attribute data. WebbA capable process is a process whose spread on the bell-shaped curve is narrower than the tolerance range/customer specifications. Process capability studies are best conducted on processes that have reduced special and common cause variation to a minimum.

WebbIn this example, only the Cpk and Ppk process capability indices are included. Ppk? Yes, there is another commonly used process capability analysis metric. That metric is Ppk, which will be the topic of our next … The process capability index, or process capability ratio, is a statistical measure of process capability: the ability of an engineering process to produce an output within specification limits. The concept of process capability only holds meaning for processes that are in a state of statistical control. This means it cannot account for deviations which are not expected, such as misaligned, damaged, or worn equipment.

"WebbCpk is an option (along with z-score and PPM or DPMO) when describing process baseline measurement in the MEASURE phase. After the MSA is complete, the Six Sigma project has a goal of improving the baseline measurement. In order to measure improvement (or lack of) there must be a starting point. This is called the baseline measurement . " - Process capability index analysis
