The concept of product lifecycle management (PLM) promises to seamlessy integrate all the information produced throughout all phases of the product’s lifecycle to everyone in the organization and supplier & customers. However, PLM focuses heavily on information systems, and how the information is structured in them. My interest is in communicating this product information, thus often the promise does not result into relevant (to my research) practices. Sudarsan et al. construct a UML based model for product information modeling. Product information during the design phase differs from the product information in the end of the lifecycle. In the design phase the information (product) seeks for it final form during iterative design. In maintenance, the product is relatively stable but much product in use information is gathered. In the later stages PLM systems cannot rely only on the CAD representations of the product, since the product in use information need to be tied into that. PLM systems need not only to to gather all the product information but also its meta-data, e.g., when was the information downloaded.
