    Are there any training courses offered dealing specifically with PBOMs, how they are built and explaining their usage? I have searched the catalogue and other DAU links but was unable to find anything of substance.


    There are many types of BOMs, or Bill of Materials.  Essentially a BOM is a list of the raw materials, sub-assemblies, intermediate assemblies, sub-components, components, parts and the quantities of each needed to manufacture an end product.  A BOM can define those products as they are designed (engineering bill of materials), as they are ordered (sales bill of materials), as they are built (manufacturing bill of materials), as they are maintained (service bill of materials), etc. For example, you asked about 'PBOMs', which depending on context could refer to 'Preliminary' BOM or 'Priced' BOM, either of which might imply different construct and use.  Different types of BOMs depend on the business need and use for which they are intended, and the terminology varies between government and industry, and even within an industry sector and within/between Services.  The bottom line however remains essentially the same - a listing of all materials, including part numbers, quantities, etc., that together constitute a complete, finished product; BOMs are hierarchical in nature with the top level representing that finished product, which may be a sub-assembly or a completed item, and BOM content is not typically standardized absent specific contract direction.
    Based on that definition and description, their importance in manufacturing, contracting, cost estimating and pricing, and system sustainment is apparent, but as they are a means to an end, vice an end in and of themselves, DAU does not offer extensive, specific training focused solely on BOM development or usage. However that does not mean there are no resources available.
    Look at the DAU Integrated Product Support (IPS) Element Guidebook (, section 4.3.4, for a general discussion of BOMs and usage. DAU Contract Management/Manufacturing (CMM) courses do address this topic at least tangentially ( CMM 100 (Surveillance Implications of Manufacturing & Subcontractor Management) discusses the purpose of a bill of materials as one of the course's enabling learning objectives. Similarly, CMM 210 (Production Planning and Control (PP&C)), as a secondary learning objective, teaches evaluation of BOMs across contractor departments for completeness, consistency, and correctness. The DAU course PQM 201B (Intermediate Production, Quality , and Manufacturing) discusses BOM information requirements, contents and BOM creation, and also shows how to use the BOM, in conjunction with related schedule and manufacturing and other information, to analyze contractor's manufacturing status, for evaluation of progress payments and other contract oversight issues. The SD-22, (Diminishing Manufacturing Sources and Material Shortages: A Guidebook of Best Practices for Implementing a Robust DMSMS Management Program) ( includes extensive discussion of BOMs in general and specifically in the context of their critical use in combatting DMSMS and obsolescence issues. The MIL-STD-3018 (DOD Standard Practice: Parts Management) ( also includes basic information on BOMs, but also a recommends minimum BOM content as well.
    While BOMs do vary greatly in complexity and usage, your question asked generically about training and other resources available. Should these existing training and information resources not address your defined, specific concerns, more detailed assistance is available from DAU PQM, Logistics, Business or Contracting professors as appropriate.
