Guidelines for implementation of statistical process control (SPC) - Part 1: Elements of SPC
Statistical process control (SPC) concerns the use of statistical techniques and/or statistical or stochastic control algorithms to achieve one or more of the following objectives:
- to increase knowledge about a process;
- to steer a process to behave in the desired way;
- to reduce variation of final-product parameters, or in other ways improve performance of a process.
These guidelines give the elements for implementing an SPC system to achieve these objectives. The common economic objective of statistical process control is to increase good process outputs produced for a given amount of resource inputs.
This part of ISO 11462 specifies SPC system guidelines for use
- when a supplier's capability to reduce variation in processes associated with design or production needs to be proven or improved; or
- when a supplier is beginning SPC implementation to achieve such capability.
These guidelines are not intended for contractual, regulatory or certification use.
