ERP
Enterprise Resource Planning (ERP) is the integrated software platform that manages a company's core business processes — financials, procurement, manufacturing execution, supply chain, and human resources — in a single unified system. The dominant ERP vendors in industrial manufacturing are SAP and Oracle. ERP owns the financial transaction layer (purchase orders, invoices, work orders, cost accounting) while PLM owns the engineering definition layer (BOM, geometry, change orders, configurations). The two systems must be kept in sync — specifically the eBOM-to-mBOM handoff — or manufacturing will build against stale design data.
Why it matters
The PLM-ERP integration is the most strategically important and most frequently misimplemented interface in a manufacturer's IT stack. When it breaks, engineering changes do not propagate to manufacturing, costs are estimated against wrong BOMs, and supplier POs are issued for obsolete components. Getting this right is a recurring theme in digital transformation programs.
