AUTOMOTIVE

Engineering decision cockpit for a global Tier-1 automotive supplier

Engineers spend their time gathering data from PLM, ERP and supplier portals instead of engineering. Wexa designed a cockpit with three governed agents for change impact, product carbon footprint and parts reuse, on one context graph.

01Case 39

The challenge

Engineering changes consume a third to a half of engineering capacity
Product carbon footprints take weeks and are now required by customers
Duplicate parts across PLM systems and ERP

What Wexa built

Change-impact agent: traces assemblies, plants, stock and orders; checks engineering vs manufacturing BOM; prices the change; drafts the change-board brief
Carbon-footprint agent: maps the BOM to emission factors per the industry rulebook; hotspots and lower-CO₂ options; sign-off by the footprint lead
Parts-reuse agent: finds look-alikes across PLM and ERP and ranks duplicates by spend and stock
Starts read-only; approval and audit on every write; EU cloud or on-premise; 12-month gated programme
