For general purchasing stuff, please look at the Finance Team pages. This page will serve as a summary on the general process we have for purchasing stuff for engineering projects

CONTENTS

BOMs

All projects have a Bill of Materials (BOM) spreadsheet in their Google Drive folder (which should also be linked in Confluence). This spreadsheet should itemize every purchase that ever needs to be made relating to a project.

The one exception we have to this currently is PCBs, in which case we utilize the Altium ActiveBOM system, and instead add the entire PCB cost to the project BOM in Google Drive

Most columns are explanatory. WBS is the work breakdown structure for the work package. We’ve somewhat retired this column as we now budget for projects as a whole (X.X.0) as opposed to a specific WP (X.X.X).

Pooled Purchases

We make a lot of purchases. To save money on shipping costs, consolidate packages, and reduce finance forms, it is helpful to pool orders!

We currently have two spreadsheets to pool the following:

McMaster-Carr: https://docs.google.com/spreadsheets/d/1kqpnw8jZDx2GO5NFUtqefRXqT1XX46iMx5ZI4euPJgY/edit#gid=0
EE Distributors: https://docs.google.com/spreadsheets/d/1YDD7SfCvcUX-2A0aKgKVb-ZtQCIAu4mKnFacT-Uho7E/edit#gid=0
- Digikey
- Mouser
- Arrow
- Newark
- etc

Adding Stuff to be Purchased

Add your item to the project BOM
When ready to order, add your item to the appropriate order sheet
1. Make sure to paste without formatting (Ctrl + Shift + V)
2. Include the correct WBS for the project (http://finishlinebyner.com)
Order!
1. If you are in no rush, just let it sit until someone places an order
2. If you need it soon, place the order yourself! (see section below)

Making the Purchase

If you need something ASAP, or the spreadsheet has built up, it’s time to buy!
