In this episode of Sourced by Cofactr, Ed tackles one of the most misunderstood—and underestimated—rituals in hardware: the BOM scrub. What sounds like a tedious spreadsheet cleanup is actually the critical bridge between a working schematic and a shippable product. Ed breaks down why engineering BOMs are almost never factory-ready, and how small data issues—typos in manufacturer part numbers, distributor-specific suffixes, outdated manufacturer names after acquisitions—create “data rot” that quietly sabotages automation and scale. Part matching, he argues, isn’t clerical work; it’s the foundation for a clean, portable, system-ready BOM that won’t collapse under the weight of growth.

From there, he reframes the BOM scrub as a strategic risk assessment spanning compliance (RoHS, REACH, PFAS), lifecycle status (NRND, EOL, last-time buys), and real-world availability. A matched part isn’t the same as a buildable part—and a missing 10-cent capacitor can shut down a $1,000 product line. Through the lens of multi-sourcing, obsolescence planning, and certification risk, Ed makes the case that the BOM scrub isn’t janitorial—it’s immunization against chaos. For hardware teams moving from prototype to production, this episode is a playbook for turning a fragile parts list into a resilient, revenue-protecting supply chain strategy.
