ISO 22514-4 is part four of the multi-series international standard that focuses on statistical methods in process management. ISO 22514-4 describes process capability and performance measures that are commonly used. ISO 22514-4 also describes a procedure for the determination of statistics for estimating the quality capability or performance of product and process characteristics. The process results of these quality characteristics are categorized into eight possible distribution types. Calculation formulae for the statistical measures are placed with every distribution.
ISO 22514-4 on statistical methods in process management and capability performance is useful for:
Many organizations have embarked upon a continuous improvement strategy. To comply with such a strategy, any organization will need to evaluate the capability and performance of its key processes. The methods described in ISO 22514-4 are intended to assist any management in this respect. These evaluations need to be constantly reviewed by the management so that actions compatible with continuous improvement can be taken when required.
The progression of ISO 22514-4 is from the general condition to the specific and this approach leads to general formulae being presented before their more usual, but specific manifestations.
ISO 22514-4 describes the importance of understanding the processes at work within any organization, be it a manufacturing process or an information handling process. As organizations compete for sales with each other, it has become increasingly apparent that it is not only the price paid for a product or service that matters so much but also what costs will be incurred by the purchaser from using such a product or service.
