Core insight: the highest-leverage signals for executives often live under the surface—in error logs, support tags, routing delays, and outcome deltas that nobody treats as a decision input. This briefing teaches a repeatable harvest pattern that turns those ‘quiet data’ streams into one-line signals you can act on in under 10 minutes. You’ll get three compact moves: (1) locate high-frequency traces that reliably precede problems or opportunities; (2) convert them into human-readable micro-signals (rate, direction, owner) with a 30–90 day baseline; (3) wire one automatic alert + simple next-step rule so the signal produces immediate action, not noise. I’ll give concrete examples (support-tag surges, approval latency, feature error spikes), a two-step prompt to distill logs into a one-line executive note, and a single action: harvest one quiet signal this week and attach a trigger rule. Result: earlier detection, measured interventions, and fewer surprises. Stay agentic.
