Bill of Material Management


Hummingbird's Bill of Material management solution helps customer manage raw materials, sub-assemblies, intermediate assemblies, sub-components, parts and the quantities of each needed to manufacture an end product. A Bill of Material can be used for communication between manufacturing partners, or confined to a single manufacturing plant. Having visibility of BOM across the entire supply chain process is key to have a successful product in the market.

BoM errors typically fall within three categories: completeness, consistency and correctness:

  • Completeness - Incomplete data is the most common BoM defect. Critical pieces of information that are often omitted includes quantity, part description, reference designation and approved manufacturers list (AML). Missing AMLs reportedly cause the majority of problems.
  • Consistency - Information in the BoM sometimes conflicts with information provided in engineering drawings and design files. For example, quantities may not match -- there may be 10 find numbers for a particular component indicated on a board, but the BoM only specifies nine. Having inconsistence language is another stumbling block and very common and varies from BoM to BoM.
  • Correctness - Incorrect data is a serious problem. Common errors include invalid manufacturer or supplier information, obsolete data and incorrect part numbers (i.e., the manufacturer's parts number (MPN) given does not match the description of the part, or the MPN is not recognized by the manufacturer/supplier).
  • Business Process Migration - This is a process of transforming the existing business process to a more lean process to improve the operational excellence of the organization.
