Every organisation pays for its effectiveness culture. Most never see the bill.
It is paid in reallocations that take nine months instead of one, in evidence that arrives after the budget is set, and in campaigns that run on because nobody is allowed to say they did not work. None of it shows up in a dashboard, which is why it is so rarely fixed.
Decisions that wait
The evidence to move money exists. Nobody owns the decision, so the money stays where it is for another quarter.
Insight that arrives late
The analysis lands after the plan is signed, so it describes last year instead of changing next year.
Evidence that loses the argument
The numbers say stop. A senior preference says continue. The preference wins, and nobody records what it cost.
The Effectiveness Culture Diagnostic puts a number on it. I trace your recent marketing decisions, value the ones your culture delayed or distorted using your own models, and agree the figure with your finance team before your leadership team sees it. Then we set out to reduce it, and measure whether we have.
