This paper described PLM considerations at Aalborg Industries A/S, a producer of engineer to order heat and steam generating systems, which is currently facing a number of challenges due to globalization, development of organisation structure and high product complexity. The product definition happens over a long period, which also introduces challenges related to managing product information. Aalborg Industries is expecting to meet these challenges by implementing a PLM system; however a number of issues must be addressed to ensure a successful PLM implementation which relate to the current information, product and process structure.
