Part numbering sounds boring until you realize it can quietly trap millions of dollars in dead inventory, slow down kitting, and make your ERP tell different “truths” depending on which customer you’re building for. We sit down with Kaitlyn Tredaway, CalcuQuote’s COO and Scott Ryan from Cetec ERP to unpack why electronics manufacturing services (EMS) companies struggle so much with internal part numbers, customer part numbers, and manufacturer part numbers and why the problem keeps coming back even in well-run factories.
We get practical about the MPN vs IPN debate. MPN-focused part numbering can unlock shared inventory across customers, better purchasing leverage, cleaner supply chain decisions, and higher inventory turns. But we also dig into the real-world friction that keeps teams on IPNs: long and lookalike MPN strings on the shop floor, MES and machine programming character limits, short MPN collisions, and the operational risk of retraining teams who have “always done it this way.” The key idea is separating inventory identity from manufacturing usability so you can standardize without slowing production.
Then we walk through what a transition actually takes. Think less “flip a switch” and more ERP-style project planning: warehouse validation, re-barcoding, data mapping, leadership sponsorship, and a clear ROI goalpost that keeps the team aligned through the painful parts. We also explore where AI can help scrub messy datasets and improve consistency in part types without using AI as a buzzword.
