Resist narrating events. Instead, cluster points by causal drivers such as revenue impact, cost to serve, and execution feasibility. Chronology buries insight; drivers reveal trade-offs. This organizes your drill-down map and keeps detours from unraveling the logic you set at the top.
Anchor each reason with a number, even a bounded estimate. Leaders decide with ranges and risk. “+$12–15M net revenue from expansion” outperforms “strong upside,” because it sets scale, invites sensitivity tests, and earns credibility when follow-up questions hit hard and fast.
Scan your reasons for duplication and dependency. If two points move in lockstep, merge them. If one point is merely an effect of another, nest it deeper. Clean boundaries sharpen memory, accelerate discussion, and prevent your answer from sounding like a padded list.
