Evidence quality

Assumptions, inferences & uncertainty

A careful review distinguishes a direct observation from an inference and an unanswered question. The basis of each conclusion should remain available for inspection.

Label the kind of statement

A log entry, a test result and an expert interpretation are different forms of information. Record what was observed and how the interpretation was reached. A working hypothesis should not gradually become a confirmed fact simply through repetition in reports.

Test the inference

Explain which evidence supports a proposed conclusion and which alternatives remain plausible. A sequence of events may support an enquiry without proving the mechanism. Document the assumptions needed for a test or reconstruction to represent the incident.

Keep uncertainty actionable

Uncertainty can be expressed as a question with an owner and a proposed next step. This is more useful than a vague disclaimer at the end of a confident report. Update the conclusion when new evidence changes its basis.

Records that help the review

Use the following as a practical starting point. Select and preserve records appropriate to the product, incident and applicable procedure.

  • Observation and source
  • Inference and supporting reasoning
  • Alternative explanations
