The honest version of "does it integrate with my software." These are the systems this industry actually runs on, and what each one means for a build.

Epicor, Global Shop, IQMS or similar covering planning, production, inventory and costing, and the anchor for anything an agent does.

Machine and operator data collection, driving both scheduling reality and the traceability records customers require.
Quality managementCompliance
ISO 9001, IATF or AS9100 documentation — control plans, first articles, non-conformances, corrective actions and audit evidence.
Customer portals and EDIDemand
Releases, forecasts and revision notices arriving through each customer's own system, on their schedule and in their format.
Supplier managementSupply chain
Approved supplier lists, incoming inspection, and supplier corrective actions when material fails.
PLM and engineering changeRevisions
Where drawing and specification revisions originate, and where a missed change becomes scrap.
