Field Service BOM Alignment for Warranty & Aftermarket Operations
A commercial bus and truck manufacturer with a global dealer network managing 150,000 active fleet vehicles across 25 international markets.
Run on Sama · Traceability & Product Data
The challenge
Service BOMs (SBOMs) used by dealership mechanics did not reflect mid model year engineering component supersessions.
Dealership technicians ordered incompatible replacement parts for vehicle repairs, resulting in repeated customer workshop visits and high warranty expense.
Service parts catalog updates lagged engineering ECO releases by up to 6 months, creating massive confusion across the global service network.
How Sama solves it
Automated EBOM to SBOM Supersession Mapping
Sama tracks component design updates and automatically generates service part supersession and backward compatibility rules.
Service Kit & Replacement Assembly Definition
Bundles discrete engineering sub components into practical field serviceable replacement kits with complete fastener lists.
VIN Specific Service BOM Generation
Generates exact as built Service BOMs for individual vehicle identification numbers (VINs) based on factory build records.
Real Time Dealer Portal Catalog Publishing
Publishes updated parts catalogs and compatibility diagrams to global dealer management systems instantaneously.
Warranty Claim Validation Engine
Validates dealer warranty claims against VIN specific SBOM configurations, preventing reimbursement for incorrect part replacements.
The outcome
- service catalog update latency reduced
- 0 monthsservice catalog update latency reduced
- dealer parts ordering errors and return logistics costs reduced
- 0%dealer parts ordering errors and return logistics costs reduced
Service catalog update latency reduced from 6 months to real time continuous synchronization.
Dealer parts ordering errors and return logistics costs reduced by 72%.
Warranty repair repeat visit rates cut by 45%, saving $2.6M in unnecessary warranty claims.
