15 Present level of maturity the issues of architecture and system have been resolved topics of extended application are now being examined includes general work on extending ERP functionality integrating PLM and preparing its use for special fields of application (e.g. plant engineering and plant operation) 4 th International Bulgarian-Greek Conference Computer Science 2008, 19/09/

17 Plant engineering and plant operation have been moving into the field of PDM and PLM application only since the turn of the millennium due to the nature of manufacturing every plant made-to-order manufacturers produce is a unique item and manufactured specifically for a client due to the plant manufacturer s products are extremely complex (an attribute of the product structure) evolves in the course of the product development process growing bills of material growing product structure accompanies a plant up to the phase of operation as an as designed, as built and as maintained structure 4 th International Bulgarian-Greek Conference Computer Science 2008, 19/09/

23 Conclusions - PDM Abramovici/ Schulte While PDM was Information and CommunicationTechnology (ICT) driven and had a narrow focus on the management of product data within product design, PLM has a manage-ment focus addressing all data, processes and applications for the entire lifespan of a product. Paul/ Paul the time for EDM/PDM solutions is not past by any means a PDM core can play a supporting role in PLM solutions and therefore deserves to be continuously extended and maintained this PDM approach could be the basis for developing specially customized as well as cost effective solutions for small and medium-sized enterprises or for serving special technical niches 4 th International Bulgarian-Greek Conference Computer Science 2008, 19/09/
