The basis of a good quality production is determined by the design of three associated quality roles:

• Standardization: standards body
• Production: operating body
• Quality support: supervisory (and assessment) body.

​

These roles are hierarchically separated from each other.

​

Standardization defines and prescribes three standards:
• Defines and prescribes production standards
• Defines and prescribes (self) control standard
• Defines and prescribes audit standards (for process and product audits)

​

Production executes according to the self-control standard.

​

Quality service checks, audits, supervises and reports:

• Checks the application of the Production standard and the self-control standard

  (is there a standard? / Is the standard applied?),

• Performs process and product audits in accordance with the audit standard,

• Supervises the realization of improvement measures,

• Provides management reports on the fore-mentioned activities.
