Enterprise Systems (ES) provide a standardized means to assist operations and management. Being off-the-shelf software, ES provide a generic approach and they have to be configured to the enterprise’s requirements. The customization of ES is a complex and costly task, therefore especially small and midsize enterprises (SME) flinch from doing so. Independent software vendors can assist SMEs in adapting ES to their needs. To be of reasonable economical value, it must be possible to facilitate the customization process with configuration mechanisms that allow generating customer specific processes and documents from a generic model-based repository. Several high-level configuration mechanisms are presented that add up to a comprehensive procedure for document variant management.
