Technologies of the Electronics Product Definition - EPD, Product Data Management - PDM and Product Lifecycle Management - PLM represent modern trends in the field of Technical Production Planning and a new quality in this sector. Efficiency of utilization of these technologies for specific manufacturing companies depends materially on correct selection of the system and correct user adaptation of the purchased technologies. The main problem in CR is that the companies do not have adequate knowledge of the issue and therefore the conceptual system of selection does not exist here. And this is why the situation of selection is based as follows: The company addresses the supply house with unclear requirements, is unable to be adequately depth-oriented and selection of the system is in principle carried out by the addressed supply house which results in the danger that the company introduces an expensive system not quite conforming to its character. Instead of the awaited effect the total costs continue rising materially. The methodology of selection of the PDM system should be designed so that the whole process of selection is managed by the company itself and is modified precisely to its requirements. This is the very topic of this paper.
