quality management system 

https://doi.org/10.1351/goldbook.08110
Part of a set of interrelated or interacting elements of an organization to establish quality policies and quality objectives and processes to achieve those objectives.
Notes:
  1. A laboratory's structure, roles and responsibilities, planning, operation, practices, rules, and beliefs are also established within the quality management system.
  2. Other common parts of a laboratory's management system are financial management and environmental management. These management systems should not be confused with a laboratory information management system.
