Week 12:- Documentation Challenge

OBJECTIVE: To create a Bill of Materials (BOM) and Bill of Parts (BOP) for the designed fixture.

THEORY:

Bill of materials: A bill of materials (BOM) is a comprehensive inventory of the raw materials, assemblies, subassemblies, parts, and components, as well as the quantities of each, needed to manufacture a product. In a nutshell, it is the complete list of all the items that are required to build a product. A BOM is sometimes also referred to as a product structure, assembly component list, or production recipe.

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

BOP INCLUDES:-

Part Number—Assign a part number to each part or assembly to reference and identify parts quickly. It is common for manufacturers to choose either an intelligent or non-intelligent part numbering scheme. Whichever scheme you use, make sure you avoid creating multiple part numbers for the same part.

Part Name—Record the unique name of each part or assembly. This will help you identify parts more easily.

Phase—Record what stage each part is at in its lifecycle. For production parts, it is common to use a term like ‘In Production’ to indicate the stage of the part. New parts that have not yet been approved can be classified as 'Unreleased' or 'In Design'. This is helpful during new product introduction (NPI) because it allows you to easily track progress and create realistic project timelines.

Description—Provide a detailed description of each part that will help you and others distinguish between similar parts and identify specific parts more easily.

Quantity—Record the number of parts to be used in each assembly or subassembly to help guide purchasing and manufacturing decisions and activities.

Bill of parts: A bill of parts is a list that contains all the required hardware and parts which are to be bought from a supplier.
