Short answer
A cadence keeps leaders informed without flooding them. The right rhythm depends on how quickly the decision could change and what evidence would justify action.
Choose cadence from the decision window
A board decision, negotiation, diligence process, regulatory event, crisis issue, and recurring watch do not need the same rhythm. Cadence should follow the decision window.
Use thresholds between scheduled briefs
Scheduled cadence handles expected review. Escalation thresholds handle material movement between reviews. That prevents silence when something matters and noise when nothing has changed.
Keep the record consistent
Each brief should use the same decision, signal, confidence, open-question, and next-action structure so leadership can see how the read changed over time.
