How to use it well

  1. Start with the decision.Write down who needs to decide what, and by when.
  2. Separate evidence from interpretation.Keep the source, date, and observable fact attached to every conclusion.
  3. Turn the finding into a move.Update the message, battlecard, roadmap question, or watchlist—or explicitly choose not to react.
05

Common mistakes

Collecting without a question. More information creates more work unless it is tied to a decision.

Treating one signal as a strategy. Look for corroborating evidence and patterns before making a large response.

Losing the source. Unsourced competitive claims become stale, risky, and impossible for sales to defend.
