This Guidance Technical Document provides guidance on selecting appropriate statistical techniques that may be useful for establishing, implementing or maintaining a quality system that complies with the requirements of ISO 9001. Guidance can be provided by looking up the requirements of ISO 9001 concerning the use of quantitative data, and then identifying and expressing statistical techniques applicable to these data. The statistical techniques listed in this technical guidance document are neither comprehensive nor exhaustive, and an organization should not exclude the use of other techniques (statistical or otherwise) to which it may benefit. This guidance technical document does not stipulate which statistical techniques must be used, nor does it make suggestions on how to apply these statistical techniques. This guidance technical document is not intended to be used for contractual, regulatory or certification purposes, nor is it intended to be used as a mandatory checklist for compliance with the requirements of GB/T 19001-1994. The rationale for using statistical techniques is that their application should contribute to improving the effectiveness of the quality system.
