Abstract: A process to structure and manage the configuration of an industrial product, taking into account selected options includes describing a set of technical objects, each technical object either representing a product function or describing an implementation method for making a product configuration for such a product function. The technical objects represent manufacturing options of the industrial product. The process further includes updating a database to clarify a definition of each technical object and its inter-relations with other objects in the configuration. The definition includes an expression of rules and constraints. The process also includes interacting with the database during the product configuration, through a selection of options, wherein the interacting includes using a knowledge management module, a contract management module, an administration module, and a mass management module.
