			=Full Protocol=

			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:

			#Item Number
			#Quantity
			#Item description. Write down unique identifying properties.
			#Link - direct link that takes one to arrive at description, source, and 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.
			#Substitution Notes. A description of what other parts would work - based on general properties, characteristics, criteria, or design rationales being made explicit.
			#Other Geographic Sources. Additional entries, corresponding to other geographical locations, may be added on other sheets of the spreadsheet, with the same Item Number. For example, for sources of parts in Chile, a different list of suppliers may be used.

			=Quality Assessment=
			To assess the quality of a BOM:
			*A BOM is deemed proper when all parts are explicit and unambiguous, where a link is provided to a purchase source. In absence of a link, a supplier phone number or contact information is sufficient.
			*Given that a stable supply chain is a common risk in manufacturing, Substitution Notes are a useful feature that would allow a builder to reason what is acceptable as a substitute, and what isn't.
