Week 12:- Documentation Challenge

Objective: To create a BOM and Hardware list (BOP) for the complete Fixture assembly.

BOM:

Bill of Material is a comprehensive list of raw materials, components, assemblies, sub-assemblies, parts, or anything which is required to manufacture the finished product. The finished product or goods may be the final product itself or a semi-finished product which is later consumed to produce a final or a larger product.

The bill of material for finished goods not only lists the components but also the quantity of each component required to produce the finished goods. If the finished product has a variant by colour, configuration, size etc., you can choose to have multiple BOM for a single product. The examples in the next section will help you understand this easily.

A well-defined BOM helps companies:

• Plan purchases of raw materials
• Estimate material costs
• Gain inventory control
• Track and plan material requirements
• Maintain accurate records
• Ensure supply robustness and reduce waste

Format of Bill of Materials

The format of bill of materials varies but it contains the essential details as discussed in the above sections. Below is the simple and easy to use bill of material format.

Types of Bill of Material (BOM)

The following are the different types of Bill of Material (BOM)

• Assembly Bill of Materials
• Configurable BOM
• Single-Level BOM
• Multi-Level BOM
• Engineering Bill of Materials (EBOM)
• Manufacturing Bill of Materials (MBOM)
• Service BOM
• Sales BOM

A ‘bought-out’ part is a part used in a machine or equipment that is not manufactured in-house by the manufacturer of the machine or equipment. These can be standard off-the-shelf parts from another manufacturer, for example a power supply cable or a rechargeable battery. The part appears in the Bill of Materials of the equipment with the Part / Model Number of the original manufacturer. Or A part that is custom-designed by the equipment manufacturer, but manufactured by a specialist manufacturer against design and material specified. In this case, the Bill of Materials contains the internal Part reference of the equipment manufacturer Bill of material of fixture assemb
