What this method prevents

A sentence combines effectiveness, safety, affordability and causation so that evidence for one part appears to support all parts.

Illustrative example

“The intervention is effective, safe and cost-efficient” becomes three independent claims with different evidence requirements.

A controlled sequence

  1. Identify every distinct assertion.
  2. Separate observations from interpretations.
  3. Separate causal, predictive and value claims.
  4. Assign sources to individual sub-claims.
  5. Identify necessary versus optional components.
  6. Create a claim register for audit.

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.
