Fourteen years ago Andrew watched profitable companies reject prescriptive analytics that were delivering 8–20 % profit lifts because leaders defended the spreadsheet methods that had made them successful in the first place. Today the same pattern repeats with AI: capable, proven tools sit unused while executives protect what already worked yesterday.
Defensiveness is not just ego – it is the single biggest drag on speed, profitability, and competitive separation in 2025. The leaders who drop it gain clarity on true contribution, make optimal decisions faster, see constraints earlier, and stop settling for “better than last year.”
If your organization is quietly defending past success instead of aggressively pursuing the next advantage, what is that posture actually costing you this year?
Andrew reveals why almost every leader instantly says they want to improve yet almost none are actively working on their own performance. He connects his 14-year-old observation about defensiveness blocking prescriptive analytics to today’s identical resistance against AI-driven insight. The highest-leverage insight: defending what already works is the most expensive habit in modern business; dropping it immediately unlocks contribution clarity, optimal decisions, constraint visibility, and the shift from incremental “better than last year” to true best-possible outcomes.
“Defensiveness is going to cost you profits. It’s just that simple. What we defend in our business is usually something that has worked for us successfully. That’s a defensive posture.” Leaders confuse organizational improvement with personal performance improvement Past success creates identity-level attachment to methods that are now obsolete Shifting from defense to offense changes the question from “Why change?” to “What’s the next advantage?” Organizations that dropped defensiveness saw 8–20 % profit lifts from analytics alone (and higher with AI) Works at every scale – from private equity portfolio companies to mid-market owners When was the last time your executive team openly discussed which sacred cows are quietly limiting growth?

Most leadership teams never measure the hidden cost of protecting yesterday’s playbook. We do – and we remove it.
