Verification & Validation (V&V): The Engineering Truth Protocol

In high-complexity engineering, a simulation is a hypothesis, and a prototype is a test. The Verification & Validation (V&V) process is the rigorous framework Edelweis uses to prove that the digital model matches physics (Verification) and that the physical product matches user requirements (Validation). This protocol ensures we are building the right thing, right.

1. The V-Model Integration

We adhere to the industry-standard V-Model to maintain a clear "Line of Sight" between initial requirements and final testing:

Verification (Design Audit)
Does the CAD adhere to GD&T? Does the FEA converge? Verifying design outputs meet design inputs.
Validation (Physical Truth)
Does the assembly survive Load Cases? Does flow match CFD? Validating the product fulfills its purpose.

2. Verification Standards (The Digital Audit)

Verification Gate Method Objective
Geometry Audit Mesh Sensitivity Studies. Ensuring simulation results are mathematically stable and independent.
Kinematic Check Mate Controllers. Verifying that all DoFs and ranges of motion are within spec.
Tolerance Audit Stack-up Analysis. Confirming cumulative variations result in 100% assembly success.
Peer Review Lead Engineer Audit. "Cold Eye" review of boundary conditions and material assignments.

3. Validation Standards (The Physical Truth)

  • Correlation Testing: Comparing physical test data (strain gauges, thermal probes) to simulation reports. Validated designs must maintain a delta within ±5%.
  • Environmental Stress Screening (ESS): Subjecting prototypes to vibration and thermal cycling to validate Fatigue & Life Cycle predictions.
  • User Acceptance Validation (UAV): Ensuring ergonomics and DFA logic function seamlessly for assembly technicians and end-users.

4. V&V Documentation Deliverables

For Enterprise partners, the V&V report is the primary document for ISO, aerospace, or medical certification:

  • Verification Matrix: A checklist proving every technical requirement is mathematically satisfied.
  • Validation Test Plan (VTP): Detailed procedures including sensor placement and pass/fail criteria.
  • Discrepancy Log: Transparent record of deviations and the ECOs implemented to resolve them.

Technical Directives

Directive Protocol
Independence The validating engineer should be different from the designer to prevent confirmation bias.
Traceability Every test result must be traceable back to a specific requirement ID in the Project Charter.
Calibration All physical testing equipment must have valid, up-to-date calibration certificates.
