Implementing a management system into a service provider organization is an important task to promote the quality of the service. Many Member States currently require management systems in their procedure of service authorization. This publication will be of use to consulting or measurement organizations when creating and implementing management systems that will help them to obtain authorization for their activities. The publication describes clearly the different requirements for consulting organizations that do and do not perform measurements. The difference between third party assessment requirements (often also used in Member States to speed up the authorization process) for certification and accreditation is explained in detail. The text is supplemented with informative examples covering tasks within the management system.
