Invite two engineers and ask them to provide a definition for some of PDMPLM related terms. Id not be surprised if you will get more than two definitions.In fact, most of PLM data models are doing exactly that providing multiple views of Bill of Materials.It related to the type of product and type of engineering and manufacturing process.No surprise. BOM is a center of universe in manufacturing (and not only) world.
People can disagree about terminology applied to BOM management. Depends on a specific domain people can call it part list, specification, formula. I guess youve heard about variation of Bill of Materials eBOM, mBOM, xBOM, etc. The amount of abbreviations in BOM is growing and often can cause confusion. Historically, people in different departments disagree about the way they manage bill of materials. As a result of that, departments are splitting and cloning bill of materials to get control and managing it in different systems. It leads to the need to synchronize and copy BOMs together with changes. Right now there are four primary participants on the battlefield: Siemens, SAP, GEPTC and IBM. The complexity of universal BOM solution and potential advantages of winning BOM battle is dependent on many functions. What might appear as a list of parts needed to build a product is today a complex reality of multiple levels, diversified disciplines and BOMs contains information about structures, electronics, integrated software, manufacturing methodology and the way products are maintained and even disposed of. There are many sources of error and mistakes can be very costly. Even for very simple products it goes beyond just mechanical and electromechanical design. It includes electronic, software and goes to services and deliveries. Engineers are using multiple tools to create design of products in each discipline. It must be manufactured, shipped, supported and (after all) re-furbished or destroyed. All these processes are going in parallel and requires sophisticated interplay in data and activities. How to connect requirements with design, plan and optimize manufacturing and run support services This is only a short list of tasks that requires BOM orchestration. All these events generate changes that must be applied into different stages of product development design, manufacturing, services. The time when companies managed BOM on the shop floor cork boards are gone. Future BOM management systems will have to be much more sophisticated, integrated and to support multiple dimensions of BOM complexity.
