Requirement capture
Translate vehicle, function, interface, duty and customer requirements into a controlled application record.
Quality & programme governanceSafety-critical work
Safety-critical work
needs visible evidence.
TCS builds quality into the handoffs between requirement, source, product, application, supply and field support.
01The assurance model
Quality is a chain of controlled decisions.
A component can meet its own drawing and still be wrong for a trailer. TCS therefore treats product quality and application correctness as connected responsibilities.
The framework below is designed to make the status of every significant decision visible to engineering, purchasing, quality, supply and service teams.
Source qualification
Review supplier capability, product evidence, change control, traceability and commercial continuity.
Incoming assurance
Define identity, visual, dimensional or functional checks according to product and programme risk.
Application validation
Record fitment, function, leakage, response, electrical behaviour and identified deviations as applicable.
Release control
Connect the approved part, specification, revision, packaging and customer programme before repeat supply.
Field feedback
Convert complaints and workshop evidence into containment, root-cause review and controlled corrective action.
Capability status
Clear separation between today and the roadmap.
This is an operating-status statement—not a certification claim.
Programme and supply assurance
- Application and part-reference review
- Supplier and sourcing coordination
- Incoming inspection planning
- Technical dossier and sample coordination
- Customer feedback and field escalation
Structured test capability
- Pressure, flow and leakage test planning
- Electrical and sensor checks
- Calibration and final-inspection controls
- Endurance and environmental test partnerships
- Customer-specific approval documentation
Assembly and localisation
- Dedicated product assembly cells
- Expanded in-house test infrastructure
- Qualified local component development
- Progressive manufacturing traceability
- Export and production-readiness systems
Customer quality dossier
Six records that protect continuity.
The exact dossier is agreed by product and customer programme. Availability varies with source, product maturity and validation scope.
Product definition
Part identity, functional role, reference values, interfaces and application boundary.
Inspection record
Defined checks, result, status, traceability reference and responsible reviewer.
Application record
Vehicle definition, open points, selected configuration and customer confirmation.
Validation evidence
Sample status, observations, test outputs, deviations and resolution actions.
Change record
Revision, reason, affected scope, review, approval and notification pathway.
Field case record
Vehicle and product evidence, symptom, containment, analysis and closure.
Nonconformance & corrective action
From field symptom to controlled closure.
Vehicle, product identity, symptom, timing and available evidence.
Protect affected stock, application or customer operation.
Separate product, application, installation and operating causes.
Define action, owner, due date and verification method.
Confirm effectiveness and update records or controls.
Supply-partner expectations
Evidence travels with the relationship.
Conformance to the agreed identity, specification, material, process and performance requirements.
Ability to connect supplied product to the relevant production, inspection and revision records.
Advance visibility of material, process, source, tooling, design or location changes that may affect the programme.
Timely containment, evidence sharing, root-cause work and corrective-action verification.
Claim boundary
What this page does—and does not—claim.
This page describes the TCS quality-management approach and capability roadmap. It does not by itself represent ISO, IATF, homologation, government approval or product-certification status.
Customers requiring a specific certificate, approval, validation report or control plan should request it by product and programme.
