Failure mode
What this method prevents
A modelled or transformed quantity is described as if it were directly observed.
Illustrative example
A measured variable may pass through calibration, spatial aggregation, model inversion and attribution before supporting a policy claim.
How it works
A controlled sequence
- Identify the original observation.
- List each calculation, adjustment, model or aggregation.
- Record assumptions introduced at each transformation.
- Test sensitivity and information loss.
- Separate observed, derived and inferred statements.
- Limit reliance to the weakest transformation junction.
Reliance note
The method supports governance; it does not self-authorise a decision.
Application must be proportionate to the task, evidence and consequence level. The output should state what has been registered, what remains uncertain and which authorised human or organisation controls release.
