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 ...
In statistical process control (SPC), the ¯ and R chart is a type of scheme, popularly known as control chart, used to monitor the mean and range of a normally distributed variables simultaneously, when samples are collected at regular intervals from a business or industrial process. [1]
Porter's four corners model is a predictive tool designed by Michael Porter that helps in determining a competitor's course of action. Unlike other predictive models which predominantly rely on a firm's current strategy and capabilities to determine future strategy, Porter's model additionally calls for an understanding of what motivates the competitor.
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.
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 ...
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.
The structure–conduct–performance (SCP) paradigm, first published by economists Edward Chamberlin and Joan Robinson in 1933 [1] and subsequently developed by Joe S. Bain, is a model in industrial organization economics that offers a causal theoretical explanation for firm performance through economic conduct on incomplete markets.
The four stages of competence arranged as a pyramid. In psychology, the four stages of competence, or the "conscious competence" learning model, relates to the psychological states involved in the process of progressing from incompetence to competence in a skill.
