A Working Group on Quality and a central quality assurance function have been established to continuously carry through control of products and processes.
Quality assurance

This involves continuous decentralized and central control of products and processes based on documentation following international standards. The central quality assurance function reports to the Working Group on Quality. Reports include suggestions for improvement that are assessed, decided and subsequently implemented.
