![]() Historically, drawing is the place where people put bill of materials for a product. Usually routing applied to manufactured parts or items.ĭrawings represents a significant part of history and confusing engineering habits. Routing is a roadmap that defines the path of part numbers across manufacturing floor by specifying workstations and labor time associated with every station. Think about navigation system with the road between different places. Interchangeable parts, substitiute items, special parts – this is only a short list of issues that comes into the discussion around part numbering process. The traditional definition of FFF (Form, Fit and Function) helps to identify the right objects. Assigning part numbers is often complicated and one of the most discussed topics. However, the trick is how to define object and how to keep it consistent with your processes. Part Number (PN) is an unique identifier that identify a single object in bill of material. This is one of the most tricky defined terms in a whole product development and BOM management story. Opposite to BOM, Part List is usually a term used to call a single level list for a specific level of assembly or sub-assembly. For example, in process industry, it can be called recipe or formula. Depends on industry, people can call BOM differently. You may also include intermediate items identifying in-process elements to facilitate planning and other manufacturing processes. It includes components, raw materials and sub-assemblies. Thinking about BOM management solution, I can see four major things that need to be defined, discussed and clarified.īill of Materials (BOM) is a list of all items required to make a parent item. It contains a recipe of your product, process and, at the end of the day, becomes a lifeblood of your product development processes. Regardless on terminology, I found BOM to be a central element in every product development organization and business. It is not unusual to spend lots of time during PLM software implementation meetings to define terms, language and meaning of things. I’d not be surprised if you will get more than two definitions. Invite two engineers and ask them to provide a definition for some of PDM/PLM related terms. BOM 101: The four pillars of every BOM management solution ![]()
