OPERATING DEFINITION

What we mean when we use this term.

A weak signal is an attributed observation whose strategic meaning is still uncertain but whose direction, novelty or combination with other evidence may change what an organization should investigate. It is not simply a news item, a prediction or a low-confidence trend.

METHOD
  1. 01Capture the observation
  2. 02Attach source, date and evidence class
  3. 03Resolve actors, geography, industry and technologies
  4. 04Separate signal strength from confidence
  5. 05Connect supporting and contradictory evidence
  6. 06Escalate to inquiry when the observation changes the question
EVIDENCE LAYERS

LIMITATIONS

What this approach does not promise.

Weak-signal analysis is not forecasting by itself. It helps organizations preserve ambiguous evidence long enough to compare interpretations, track change and decide what deserves deeper inquiry.
