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