“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.”
Every experienced leader Andrew Bielat asks will instantly say they are trying to improve. When he quietly adds, “I mean your own performance as a leader, the energy in the room shifts. The same autonomy and confidence that earned them their position now quietly blocks the very examination required to keep growing.
Fourteen years ago he watched successful executives reject prescriptive analytics that were routinely delivering 8–20 % profit increases because they were protecting the spreadsheet methods that had made them successful yesterday. Today the identical pattern repeats with artificial intelligence: proven, accessible tools remain on the shelf while leaders defend what already worked.
The hidden cost is not just missed technology; it is the persistent choice to protect past success at the expense of future advantage. When defensiveness drops, four measurable shifts appear immediately: true contribution clarity, faster optimal decisions, earlier visibility of constraints, and the replacement of “better than last year” with best-possible outcomes. In the current environment of accelerating automation and AI, protecting yesterday’s playbook is the single most expensive habit most leadership teams never measure.
Most executive teams have never quantified what protecting past success actually costs them today. We measure it precisely—and remove it.
