Have you ever taken a design for a physical product through to production? If you have then you’ll appreciate the need for a solid and useable Bill of Materials. Have you ever tried to develop a maintenance program for a physical product or system? If so, then you’ll know how pivotal the Bill of Materials [BoM] was in helping you define the modularity and level of spares inventory required. I believe there is an underlying assumption made by businesses struggling with the transition of a new product into production and deployment – that the development BoM is automagically transferable without rework and review.
