Core insight: many executive mistakes aren’t the primary choice but the unattended ripples that arrive days or quarters later. The Cross‑Impact Matrix is a rigid, time‑boxed habit you run before committing to any meaningful move: list the decision, scan six impact domains (revenue, ops, legal/regulatory, brand, morale, technical debt), score direction and magnitude, and attach one tiny mitigation for any cell above your risk tolerance. In ten minutes I’ll give the exact one‑page matrix, a 3‑question probe you run per domain to avoid shallow answers, and three action patterns: immediate soft‑shields, monitoring probes, and pre‑committed rollback triggers. I’ll include two constrained AI prompts: (A) surface the single likeliest second‑order effect per domain with supporting evidence, (B) draft a one‑line mitigation and a 72‑hour probe you can assign. Pilot: run the Matrix for one imminent decision this week and publish the top two mitigations. Fast action: draw the six domains and score one decision now. CTA: subscribe. Stay agentic.
