I know how to multiply by 2.

Most of us do.

If a business has $5 million of revenue today, I can put $10 million into next year’s forecast.

The spreadsheet will accept it without asking a single question.

Business does not work that way.

A useful forecast must answer something more difficult: How?

If we expect growth, I want to understand: What markets will create it? Which products? Which customers? What capacity will be required? Who has responsibility? What investment comes first? What could prevent the plan from happening? And by when will each step occur?

Without those answers, a forecast can become little more than mathematical optimism.

Numbers Should Create Questions

Finance is useful because numbers force a conversation.

Why did margin decline? Why is revenue growing while cash is tightening? Why are receivables increasing faster than sales? Why is one location performing differently from another? Why does the budget assume an outcome that operations cannot support?

The value is not in producing another report. The value is in finding the question that the report should make us ask.

Build the Road Map

A road map does not have to predict the future perfectly. It needs to connect the desired result to actions that can actually be taken.

If circumstances change, the road map changes. That is not failure. That is management.

The mistake is pretending that the destination alone is a strategy.

A business should be able to explain not only what number it wants to reach, but what has to happen between today and that number.

That is when a forecast becomes useful.
