Integration
PLM integration is the discipline of connecting the product lifecycle management system to the enterprise systems that author, consume and change product data: CAD for design authoring, ERP for procurement and cost, MES for shop-floor execution, ALM for embedded software, QMS for quality events and supplier systems for the extended enterprise. It defines which system is authoritative for which data, which release events trigger data movement, and how as-built and quality records return to the product record.
In context
A machinery maker releases an engineering change in PLM. The approved ECO updates the EBOM, manufacturing engineering revises the MBOM and routing, ERP receives the new MBOM at release and regenerates work orders, MES executes against the new routing, and the supplier portal notifies the two affected suppliers of the revised specification. As-built serial data flows back to PLM. That end-to-end path, triggered by one release event, is PLM integration working.
Why it matters
Integration is where PLM value is realized or lost. An isolated PLM vault is an expensive file server; an integrated one is the backbone of a digital thread. Most PLM implementation failures attributed to the tool are integration governance failures at one of six seams.
