These templates are brought to you by Arena - www.arenasolutions.com

We've done our best to create a useful BOM template that you can start using today. But remember—while Excel BOM templates are a good place to start, they can ultimately work AGAINST business goals and not for them. Check out the chart below to see how Excel BOMs stack up against a BOM and change management solution.

Excel BOMs can be exported from a CAD or ERP system, but cannot be shared in a controlled environment. When complex or multiple linked BOMs must be managed and shared, control is easily lost. Arena is designed to help manufacturers capture product data and share accurate up-to-date bill of materials with partners, suppliers and contract manufacturers.

It can be difficult to tie multiple product BOM spreadsheets together to analyze and understand assembly relationships, and making repetitive and tedious data entries wastes time. With Arena, it takes no time at all to view immediate and top-level assembly relationships for an item or assembly.

With Excel it's difficult to track changes and determine the overall impact a change has on other assemblies. Arena provides manufacturers with a way to view differences between adjacent or discontinuous revisions of a specific assembly, and track changes to quantity, name, number, reference designators and more.

Comparing multiple Excel BOMs can be a challenging and time-consuming process. Because Arena is built on a relational database, it's easy to compare differences like quantity, reference designator, and substitute items between an item’s BOM and any number of other items’ BOM.

Pulling cost data from an Excel BOM spreadsheet is a laborious and frustrating process. Arena provides a way to track your fully costed BOM and/or product for prototype and production costs on assemblies and products. Manufacturers can use quotes or estimates to calculate the percentage costs of various components or assemblies for complete products within Arena as well as view price, target cost and standard cost for each item.

With Excel BOMs, it's difficult to identify which spreadsheet file is the latest version and whether the revision is correct. In Arena, manufacturers can visually track item, assembly and product status as it moves from concept to design to production.

When BOMs are built in a spreadsheet, there are limited ways to manipulate the data, and it can be difficult to create personalized views for everyone who needs access. Arena offers role-based views of the product structure (e.g., indented, flat, sourcing, custom) based on a user's specific business needs.

With Excel, product revisions are tracked with spreadsheets and controlled file shares. BOM management capabilities in Arena help manufacturers retain product history with redline comparisons between current and previous revisions. This allows complex product history and changes to be viewed quickly and easily.

Spreadsheets can be locked and password protected, but the data can be edited and re-saved easily, putting intellectual property at risk. With Arena, you can control who has access to the product data, as well as how much access and interaction each user has.

Content Description

BOM Level shows the hierarchy of the parts and assemblies in the BOM. Level 0 (zero) is the top assembly being described.Part number lists the unique company part number. Do not place manufacturers part numbers here.Part Name is the unique part name.Revision is the revision of the part used in this assembly.A detailed description of the part.

Used with PCBAs, this lists the location on the board of the part on the BOM.This is an open note field to describe part information which is specific to this BOM.

This example shows a multi-level BOM for a GPS product. Each subassembly is listed along with the components that make up that subassembly. An individual part may be listed in the BOM multiple times if it is included in more than one subassembly.

Commonly, quantity is the number of parts needed in the assembly or subassembly. However, when used with the unit of measure, it can describe the amount of something needed- like 2 inches or 3 pints.

Unit of measure describes how you use or buy the part. Most commonly UOM is each, but it can also be standard measures like feet, inches, pints, drops, box…
