Note: Many people hope to use Excel to manage bills of materials because it's commonly available, relatively cheap, and very familiar. While we've tried to make a useable BOM template, the fact is that Excel makes a really poor BOM tool compared to a specialized PLM database, and in most cases we don't recommend its use. Some of the risks of using Excel: 1 Use caution when sorting. Since cells are not tied together, sorting a list by, say, part Number or Type risks mismatching adjacent cells. Any SUM() that relies on rows should also be checked. 2 Inspect each BOM carefully after every edit. You'll be entering the same data over and over again and any cell can be changed (even accidentally), so it's likely that a child part number or description on one assembly may not match the same part on a different assembly. 3 Changes in one place won't get propagated across all other assemblies. Each spreadsheet must be separately discovered and updated (imagine changing the supplier source for a single screw or resistor). 4 Watch out for proprietary data, which may need to be cleaned before sharing with your supply chain (do you want your new suppliers to know what you pay your current suppliers?). 5 Carefully verify that units of measure are consistent (no mixing "each" and "gram") and calculated to ensure that the cost roll-up is correct. If a wire is specified in mm, and purchased in cm, will that conversion be caught? 6 When you decide to adopt a true BOM database system, you'll find that spreadsheets with little or no formatting will import easier than highly formatted (and more readable) spreadsheets. This BOM spreadsheet template will be somewhat useful for importing into a PLM database, but be careful about making significant changes (for example, do not put supplier parts directly below home parts). 7 Ensure you have access to all released BOMs every time you revise an item. Searching across spreadsheets to discover where a specific item is used is difficult, slow and error-prone. 8 Keep good records. There is no audit trail to identify why or when a change was made, or who authorized it. 9 Review and enforce business rules, such as item numbering and data revisioning, change approval authority, and using approved suppliers. 10 Verify each item's release status (pending, released, canceled) and lifecycle (prototype, production, obsolete) to ensure production assemblies aren't using prototype, unreleased or canceled parts. Excel is a very cheap solution that could easily cost you a lot of money in time & errors. On the other hand, PDXpert PLM offers: 1 Automatic assignment of part numbers according to specified rules 2 Free-form text searches to precisely locate exact matches and possible alternate parts

3 Snapshot duplication of an existing BOM for modification 4 Drag and drop of complete items onto the BOM 5 automatic application of each child item's current revision to existing BOMs; the released assembly always shows the latest released child item revision 6 Built-in "where used" lists for each item in your database: what assemblies use it, where it appears as a source, and what changes have affected it 7 Instant information about each item's release status and lifecycle 8 Unlimited supplier sources with preferred rank 9 Design, production and acceptance files attached directly to database items, for immediate viewing by engineers, quality personnel and supply chain managers 10 Data export for supply chain data exchange 11 A full audit trail of all changes You can download a free, fully-functional evaluation of PDXpert PLM now.
