I manage the marketing budget for maximum return, funding what performs and cutting what doesn't.

How Aurelius might see it

One way to read this — take what fits, leave what doesn’t.

You're treating budget decisions like a scoreboard — fund the winners, cut the losers. The real problem is that you might be optimizing for what's easy to measure right now, while quietly starving the work that builds future demand. Short-term performance signals can lie.

The short answer

Cutting what looks weak and doubling down on what looks strong feels disciplined. But research on dynamic budget allocation shows that past performance is a lagging signal. Some budget should go toward building demand you can't yet measure — not just harvesting demand that already exists.

You're running a tight ship — fund what performs, cut what doesn't. That sounds right. But research on how budgets actually work across products and markets shows a consistent trap: performance data tells you what worked yesterday, not what builds tomorrow. Channels that grow future demand often look inefficient in the short run. Cutting them feels smart until the pipeline runs dry. Marcus wrote to act on what is fitting, not just what is convenient. Funding only proven performers is convenient. It's also a way of letting the data make your decisions for you — which means you're not really managing the budget, the budget is managing you. This week, pick one line item you've been quietly shrinking because it's hard to measure. Ask yourself honestly: is it underperforming, or is it just harder to track? If you can't answer that clearly, that's your first real budget decision to make.
