BOM Wars, Part 2: Why Engineering, Manufacturing, ERP, MES, Service, and AI Still Can’t Agree
The BOM debate is back. And somehow, it got even more dangerous.
In this Future of PLM panel, Michael Finocchiaro brings together Christine Longwell, Gus Quade, Brion Carroll, Pat Hillberg, David Schultz, and Oleg Shilovitsky for a high-energy debate on one of the most persistent fractures in product lifecycle management:
Who really owns the Bill of Materials?
Engineering says the EBOM defines the product.
Manufacturing says the MBOM defines what can actually be built.
ERP says the operational BOM is what matters.
MES wants execution context.
Service wants the as-maintained truth.
And AI? AI is useless unless all of this data is normalized, contextualized, and connected.
This episode goes deep into EBOM vs MBOM, recipes vs discrete manufacturing, fashion vs aerospace, service BOMs, circular economy, Conway’s Law, ISA-95, product memory, data governance, and why every “single source of truth” eventually collides with organizational reality.
The conclusion?
The BOM is not just a list of parts.
It is a battleground between systems, silos, budgets, ownership, and the future of industrial AI.
