Die Arbeit nutzt drei Fallstudien, um Anforderungen an die Methode abzuleiten. Die Anwendung der vorgeschlagenen Methode in zwei Aktionsforschungsprojekten zeigt die Anwendbarkeit in der Unternehmenspraxis und dient der Nutzenbewertung der Methode.
The possibility of companies to flexibly respond to changing customer and business requirements, essentially depends on their ability to provide consistent and error-free master data across applications and business processes. The decentralized organizational structure of companies acting globally, however, lead to master data being held redundantly in multiple isolated applications. Eliminating this redundancy necessitates the integration of master data. The thesis therefore develops a method for the company-wide integration of master data. By defining a procedure model with corresponding techniques the method guides data architects and master data managers to systematically integrate heterogeneous master data. Thematically, the main topics of the method comprise metadata management, the integration of metadata in data models and architecture patterns for consistent storage and distribution of master data. The thesis makes use of three case studies to derive requirements on the method development, while two action research projects show applicability of the proposed method and serve evaluation of its benefit.
