4.X — The One Period Rule #
If you haven’t succeeded in a change effort within one period, you are not going to succeed in it alone.
A period is 28 days. That’s the unit of time a restaurant actually runs on — not a month, not a quarter, not a fiscal year. A period. And one period is all the runway a change effort gets before the window closes.
This isn’t a comment on your capability. It’s a comment on human nature and organizational inertia. Change that doesn’t gain traction in the first period almost never gains it later — because the window for momentum is short, resistance hardens fast, and the people around you learn that if they wait long enough, things go back to the way they were.
The snowball that doesn’t achieve critical mass doesn’t stay a snowball. It melts. And by the time it becomes an avalanche — by the time the problem is large enough and urgent enough that nobody can ignore it — you’re no longer managing a change effort. You’re managing a crisis. And crisis management almost without exception requires someone from outside the building who can see what you can’t.
Not because you’re blind. Because you’re inside it.
