Core insight: competitive intelligence is only valuable when it produces a constrained, executable response—most competitive scans become unreadable noise. This briefing teaches a repeatable One‑Card Competitive Scan you can produce in under 60 minutes and use in real-time: (1) a two-line fact of change (what moved and by how much); (2) a short implication statement (one sentence: what it threatens or enables); (3) one immediate tactical response (owner, three-step play, rollback condition) with a 72‑hour execution window. Supporting moves: how to pick the right signals to monitor (product, pricing, distribution, partnerships), exact AI prompts to compress public signals and internal telemetry into the card, and an account‑ability pattern so the card forces action not debate. Finish with a single pilot: run a One‑Card Scan on one competitor or adjacent market actor this week, publish it to your ops channel, assign an owner, and subscribe. Result: faster, clearer defensive and offensive moves. Stay agentic.
