Billy Beane's A's didn't win on home runs. They won on a small statistical edge — a few percentage points of on-base percentage — applied relentlessly across thousands of plate appearances. No single at-bat looked different. The season did.
Decisions compound the same way. A leader makes hundreds of meaningful calls a year — hires, prices, priorities, hard conversations. Run them through a principled process and the research-backed result is roughly a ten percent improvement in decision quality. Ten percent sounds modest. It isn't. A slightly better hire stays a year longer. A slightly better-handled conflict doesn't metastasize. A slightly more honest price keeps a customer a decade. Multiply a small edge by a year of choices and you've changed the enterprise; multiply it by a career and you've changed a community.
But — and this is the whole game — an edge you don't measure is an edge you don't keep. The loud noise version of this is an enterprise that hums along, scorecard green, with decision quality left entirely to instinct. The quiet noise version is a leader who deeply believes in principled decisions and couldn't tell you the last time he actually ran the process.
So make it binary and make it weekly: add a PDM column to your scorecard. Did the significant decisions this week go through the chart — yes or no? Not 'were they good decisions' — that's a lagging indicator you'll argue about. Just: did we run the process? On-base percentage, not highlight reels. The habit is the edge.
This week's prompt: "Where have you seen the compound effect — one modestly better decision that paid off far beyond its size months or years later? Or the reverse: a small unprincipled call that compounded into something expensive?"
What would your enterprise look like if every significant decision this year had been 10% better?
