EDM systems manage the lifecycle of technical projects. They administer different kind of documents and data and demand often a high integration in existing CAD- and ERP systems. The demands on the EDM systems vary from company to company. In most cases the adaptability of the solution instead of technical features are demanded. The timeframe of the introduction depends on the complexity of the solution and the integration into the existing IT-architecture. The introduction of an average complex solution takes two to three month.
