Abstract: A method for controlling a supply chain management in product updates includes, first, a product change project that is determined by defining a type and version of equipment or systems to be changed and defining deadlines for work kits. These deadlines are completion dates for the production of a product update. Next, one or more of the work kits is processed, and an outcome of the work kits includes at least one indication pertaining to a manpower requirement for an implementation of the product change. Information about the type and version of the equipment or systems to be changed and the deadlines for the work kits are forwarded to at least one service organization. Information is then received from the at least one service organization about the available working capacity. Finally, product change quotas are defined as a function of the defined manpower requirements for the implementation of the respective product change and of the received information about the availability of working capacity.
