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 ...
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 ...
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.
A process capability analysis may be performed on a stable process to predict the ability of the process to produce "conforming product" in the future. A stable process can be demonstrated by a process signature that is free of variances outside of the capability index. A process signature is the plotted points compared with the capability index.
Another way to think about a capability is that it is an assembly of people, process and technology for a specific purpose. [4] Capability Management is the active management, over time, of the portfolio of capabilities in a firm – their development and depreciation in conscious response to changes in the business environment.
The Capability Maturity Model was originally developed as a tool for objectively assessing the ability of government contractors' processes to implement a contracted software project. The model is based on the process maturity framework first described in IEEE Software [2] and, later, in the 1989 book Managing the Software Process by Watts ...
Capability to produce the technology in a laboratory environment. Required investments, such as manufacturing technology development identified. Processes to ensure manufacturability, producibility and quality are in place and are sufficient to produce technology demonstrators. Manufacturing risks identified for prototype build.
The Capability Maturity Model Integration (CMMI) defines a process area as, "a cluster of related practices in an area that, when implemented collectively, satisfies a set of goals considered important for making improvement in that area." Both CMMI for Development v1.3 and CMMI for Acquisition v1.3 identify 22 process areas, whereas CMMI for ...
