Requirement definition
Clarification of function, dimensions, interfaces, materials, operating conditions, quantities and expected technical outputs.
Vehicle Engineering Services
Supplier Research & Technical Sourcing
Engineering-led supplier research for vehicle systems, components, prototype parts and production-ready solutions. TLG SYSTEMS supports the transition from a technical requirement to a clear and comparable sourcing package.
Engineering-Led Sourcing
A supplier quotation is useful only when the technical scope is clear
Vehicle projects often lose time because suppliers receive incomplete drawings, unclear interface requirements or non-comparable requests. We help define the requirement, identify suitable supplier capabilities and structure the technical data required for reliable quotation and evaluation.
Technical suitability comes before unit price
The lowest quotation may not be the lowest project cost. Component compatibility, tooling, validation, lead time, production capacity, quality controls and change-management capability must be reviewed together.
Service Scope
Support from requirement definition to supplier comparison
The work scope is configured according to the vehicle project, component maturity and available technical data.
Supplier capability research
Identification of suppliers with the relevant manufacturing, engineering, testing, assembly or system-integration capability.
RFQ package preparation
Organisation of drawings, specifications, quantity assumptions, quality requirements and commercial comparison inputs.
Technical quotation review
Comparison of supplier proposals against the defined requirement, including exclusions, deviations and missing technical information.
Alternative and second-source research
Evaluation of alternative components or manufacturing sources to reduce supply risk, cost pressure and dependency on one supplier.
Technical coordination
Coordination of open technical points, interface clarifications, drawing revisions and prototype requirements during sourcing.
Typical Sourcing Areas
Vehicle systems, components and manufacturing processes
Supplier research can cover complete systems, custom components, prototype quantities or series-production requirements.
Door systems, actuators, control units and emergency components
HVAC systems, auxiliary equipment and mounting components
CNC-machined shafts, pins, bushes and mechanical components
Laser-cut, bent and welded sheet-metal assemblies
Electrical harnesses, sensors, switches and interface components
Passenger-area, accessibility and interior components
Custom brackets, mechanisms and vehicle integration parts
Prototype parts and low- or medium-volume production
Drawing-based, sample-based and reverse-engineered components
Alternative suppliers and production-capacity support
Sourcing Workflow
A controlled process for technical and commercial comparison
Define
The component function, interfaces, quantity and project expectations are clarified.
Prepare
Available drawings and specifications are structured into a consistent sourcing package.
Research
Suitable suppliers are identified according to the required capability and project conditions.
Compare
Technical scope, deviations, tooling, lead time and quotation assumptions are evaluated.
Coordinate
Open points are followed through prototype, revision and supplier nomination stages.
Project Outputs
Clear information for faster sourcing decisions
Technical requirement summary
Defined component functions, critical interfaces, materials, quantities and project-specific requirements.
Supplier capability shortlist
A structured list of potential suppliers matched to the required product or manufacturing capability.
Technical comparison matrix
Side-by-side comparison of compliance, deviations, tooling, prototype conditions, lead times and technical risks.
Open-point and action list
Traceable technical questions and required actions for the customer, engineering team and potential suppliers.
Supplier selection and commercial nomination remain under the
customer’s authority. TLG SYSTEMS provides technical research,
engineering evaluation and sourcing coordination support.
