In a recent post (one of my most popular), I gave a very short answer to the question of whether PDM and PIM are the same thing. The answer was a resounding "NO". Let's elaborate on this a bit further. Historically, product management (PM) meant mostly engineering data. In fact, PM was seen as a common layer shared across engineers and manufacturers to translate data from one domain to another. Engineers would provide classifications and attributes for components and materials to support the growing need of manufacturers to standardization by identifying similar components/materials, eliminating redundancy, and establishing a preferred parts list. The data would also be available to R&D and QA, for example. These particular processes along with version control are part of Product Life-cycle Management (PLM) discipline which includes PDM. More specifically, PDM is a capability to "reliably capture and maintain the definition of a product and related data throu...
