How DFV Works
A controlled engineering chain that transforms design intent into verifiable evidence and governed lifecycle decisions.

Traditional design states what a system should do. DFV defines how that statement will be demonstrated using identifiable assets, measurable evidence and governed engineering assertions.
Example
Assertion: Heating plant must provide 650 kW at design conditions.
Evidence: measured flow × temperature difference, calibrated heat meter, equipment status and commissioning data.
Lifecycle: a replacement heat pump triggers engineering review and re-verification.
