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. [1] The concept of process capability only holds meaning for processes that are in a state of statistical control. This means it cannot account for ...
The process capability is a measurable property of a process to the specification, expressed as a process capability index (e.g., C pk or C pm) or as a process performance index (e.g., P pk or P pm). The output of this measurement is often illustrated by a histogram and calculations that predict how many parts will be produced out of ...
Once a process is put into a state of statistical control, process capability is described using process capability indices, which are formulaically identical to P pk (and P p). [disputed – discuss] The indices are named differently in order to call attention to whether the process under study is believed to be in control or not.
Process capability index (C pk), a measure of process capability; CPK coloring, a way to color atoms when visualizing molecular models; Creatine phosphokinase, an enzyme found in humans, or alternatively a blood test for it
ISO/IEC 15504 is the reference model for the maturity models (consisting of capability levels which in turn consist of the process attributes and further consist of generic practices) against which the assessors can place the evidence that they collect during their assessment, so that the assessors can give an overall determination of the organization's capabilities for delivering products ...
In fact, ISIR is like the Warrant and Inspection Report of PPAP document package. PPAP document package includes some other document such as PFMEA, control plan, drawing, MSA, capability data etc. Besides ISIR document, other documents like that of PPAP is normally required by Volkswagen and Hyundai for release of a product and process. The ...
Control charts are graphical plots used in production control to determine whether quality and manufacturing processes are being controlled under stable conditions. (ISO 7870-1) [1] The hourly status is arranged on the graph, and the occurrence of abnormalities is judged based on the presence of data that differs from the conventional trend or deviates from the control limit line.
Data must allow for statistical analytics and trend analysis of process consistency and capability. [3] A correctly implemented procedure will minimize overreactions to individual production outlier events and guarantee genuine process inconsistency are detected.
