Reallocate the budget quarterly, not annually
An annual plan is a forecast you stop questioning. A quarterly reallocation is a decision you keep making.
The teams that compound fastest are not the ones with the best plan. They are the ones who change the plan on evidence, on a schedule, without it being a crisis.
Annual plans decay quietly
A budget set in November encodes what you believed in November. By March, two of those beliefs are wrong — a channel saturated, a competitor changed strategy, a cost per acquisition drifted. The plan does not tell you which two, and nobody is looking, because the plan was approved.
The failure mode is not that the plan was bad. It is that it stopped being a decision and became a default.
Quarterly is frequent enough to matter, slow enough to be true
Monthly reallocation sounds more responsive and mostly is not. Most channels need six to eight weeks to produce a signal you can trust, so a monthly cycle reallocates on noise and then reallocates back.
Quarterly gives each channel time to prove something while keeping the budget honest four times a year rather than once.
Make the reallocation cheap to do
The reason teams do not reallocate is that it is expensive — new forecasts, renegotiated targets, an uncomfortable meeting. Anything that costs that much happens rarely.
So lower the cost deliberately:
- Agree the reallocation rule up front, so the quarterly conversation is arithmetic rather than politics.
- Hold a stated share — ten to twenty per cent is common — as explicitly unallocated, so moving it is not taking it from someone.
- Report against blended numbers, so nobody has to lose in order for the business to win.
The compounding is the point
Each cycle inherits what the last one learned. That is what makes performance accelerate rather than plateau, and it is the difference between a year of twelve monthly reports and a year of four real decisions.
