Introduction
A complete Bill of Materials (BOM) specifies parts/materials/resources needed for a build, and specifies where/how to get them. A formal BOM should include the following for each specified purchase item:
- Quantity
- Item description. Write down unique identifying properties.
- Link - direct link that takes one to arrive at description, source, or price (whenever available)
- AVL - Approved Vendor List - this defines what vendor the item can be purchased from. If a specific Link is provided above, the AVL must also be filled out. This specifies what may be substituted. If it doesn't matter, write Open/Any. If a specific manufacturer is required, write down that specific manufacturer or distributor. The AVL may also be specified in the negative, such as - do not buy from Manufacturer X.
- AVL PN - Approved Vendor List Part Number - specify the manufacturer's or distributor's part number whenever possible.
- MOQ - Specify the Minimum Order Quantity
- Lead Time - time to doorstep - or required from the placement or order to arrival of product at your doorstep. If shipping is not included, specify instructions for how to ship/pick up/deliver the item.
- Price. Critical element for assessing cost to performance ratios of desired products.
