Bill of Materials - BOM
  
You know when you’re trying to assemble a piece of Ikea furniture, and all you have is a pictograph of all the pieces and visual step-by-step instructions that look easy, but are actually almost impossible in reality?
Well, a bill of materials, or BOM, is basically the pictograph of all the pieces. A BOM is a list of all materials and parts needed to build or fix something. In the biz world, BOMs are an important part of engineering and manufacturing.
