PLM (Product Lifecycle Management) systems organize product data from concept through manufacturing and end-of-life. Engineers design (CAD), manufacturers build (BOM, process specs), supply chain sources parts, service teams maintain. PLM is the single source of truth. Systems like Siemens Teamcenter, Dassault 3DEXPERIENCE store designs, track revisions, link CAD to BOM to factory floor. Mastery takes 6-8 weeks. Manufacturing, automotive, pharma, aerospace require PLM skills. Engineers managing product data at scale earn 20-30% premium.

What is PLM Product Lifecycle

PLM (Product Lifecycle Management) is a system managing product data from concept to retirement. It stores CAD designs, specifications, bills of materials (BOM), process instructions, supplier info, and quality records. Everyone (design, manufacturing, supply chain, service) accesses the same data, one source of truth. Workflow: Engineer designs product in CAD. PLM captures design, extracts BOM (list of parts). Supply chain buys parts. Manufacturing reads PLM for assembly instructions (which tool, which torque). Product ships. Service team accesses CAD and service bulletins for repairs. If design changes, PLM version updates, all downstream processes see change.

❓ FAQ

What's the difference between PLM and ERP?
PLM = product data (designs, specs, BOM). ERP = business processes (finance, purchasing, inventory). PLM feeds ERP. Design in PLM produces BOM; ERP buys parts based on BOM. Both needed; they integrate.
How do I manage CAD revisions?
PLM stores CAD files, tracks versions. Designer saves v1 of engine block. Feedback → v2. Feedback → v3 (approved). PLM shows who made each change, when, and why. Enables rollback if needed. Prevents 'which CAD is current?'
How does PLM talk to manufacturing floor?
BOM in PLM → process instructions (which machine, which tool, which torque spec) → floor production system (MES = Manufacturing Execution System). Shop floor reads instructions and executes. Changes in PLM update floor instructions real-time.
Can multiple teams edit the same design simultaneously?
Traditional PLM: one person checks out file, edits, checks in. Others wait. Modern cloud PLM (3DEXPERIENCE): real-time collaboration like Google Docs. Multiple engineers editing same CAD simultaneously, changes merge.
What's a BOM (Bill of Materials)?
List of parts needed to build a product. Engine: 4 pistons, 1 crankshaft, 8 spark plugs. BOM is hierarchical (engine is subassembly of vehicle). Engineers define BOM in CAD; PLM extracts it; supply chain buys parts; manufacturing assembles.
