Multi Factory Plant Specific MBOM Reconciliation in Automotive Assembly
A global automotive conglomerate producing a high volume crossover vehicle across 4 assembly plants in North America, Europe, and Asia.
Run on Sama · Traceability & Product Data
The challenge
Each manufacturing plant used localized welding fixtures, stamping tools, and local tier 2 component suppliers, creating 4 distinct MBOM structures.
Engineering released a universal master EBOM, but reconciling it across 4 unique plant MBOMs required hundreds of manual engineering hours per change.
Plant specific BOM errors led to mismatched weld nut sizes and incorrect fastener torque specifications on European assembly lines.
How Sama solves it
Multi Plant MBOM Variant Workspace
Sama displays the master EBOM alongside side by side comparison views of all 4 plant specific MBOMs simultaneously.
Localized Part Number & Sourcing Mapping
Maps universal engineering part numbers to plant specific localized supplier part numbers and packaging configurations.
Automated Multi Site Change Propagation
Propagates master engineering ECOs to all 4 plant MBOMs while preserving plant specific tool routings and station assignments.
Plant Process Capability Checking
Validates that incoming component geometry is compatible with each plant specific robotic welding fixture.
Multi Site ERP Master Data Sync
Pushes verified, plant specific MBOM files directly to local SAP and Oracle ERP instances globally.
The outcome
- multi plant ECO deployment engineering effort reduced
- 0%multi plant ECO deployment engineering effort reduced
- accelerated global vehicle design change rollout
- 0 weeksaccelerated global vehicle design change rollout
Multi plant ECO deployment engineering effort reduced by 80%.
Zero localized assembly line fitment errors during cross plant vehicle platform updates.
Accelerated global vehicle design change rollout from 8 weeks to 5 business days.
Representative scenario: a modelled industry situation showing how this accelerator applies. Figures are projections, not a named client result.
Capabilities used
Every accelerator is assembled from the same capability layer, so a workflow you adopt here shares its foundation with the rest of the portfolio.
