General Configuration Management (CM) is an indispensable aspect of NATO interoperability. Proper planning and execution of CM through a system??s Life Cycle ensures that defence programmes (national@ multi-national or NATO) run efficiently@ and that product interfaces and features are consistent with Alliance operational needs. Configuration Management is undertaken at more than one level of responsibility@ ranging from Acquirer level@ main Supplier level@ sub-supplier level@ to depot and field support levels. Each level is responsible for executing one or more parts of the Life Cycle CM process. CM applies to@ and utilizes the information from@ all Life Cycle processes to maintain the product configurations. It is not a stand-alone process operating in isolation. Aim The aim of this Publication is to implement the NATO Policy for Systems Life Cycle Management (SLCM) and the agreement by Nations in STANAG 4728 to make CM a mandatory management process for the full Life Cycle of NATO programmes and systems. The goals are to achieve interoperability@ mitigate risk@ and make effective use of NATO capabilities in joint operations. Applicability This policy applies to Nations and NATO Authorities of defence related capabilities in NATO operations. This Publication may not be used in contracts.
