Configuration Management Best Practices

Configuration management (CM) is used for the configuration of complex systems in many fields, such as IT, aeronautics, shipbuilding, space systems, nuclear power plants, etc. and is indispensable for the long-term operation of any large facility. In the Engineering Department, configuration management consists of managing the technical description and layout of the accelerators and transfer lines (and their various components), as well as managing all the modifications made during their evolution over time. It is about all the processes that ensure the conformity of the accelerators with the requirements of their operation, throughout their life cycle. The aim is to provide a clear and coherent representation of the CERN main technical facilities at a given point in time. This paper will present, the best practices that constitute the configuration management of accelerators and transfer lines in the EN-ACE group.
