Building a financial model that actually helps you make decisions
A useful model is judged by the conversations it enables, not by its level of detail.

Financial models tend to grow in precision and shrink in usefulness. Detail accumulates, assumptions become buried, and eventually only one person can operate the file.
A decision-focused model works differently. It begins with the question being asked and includes only the structure required to answer it.
Separate assumptions from mechanics
Assumptions should sit in one visible place, expressed in business language. When leadership can adjust an input and watch the consequence, the model becomes a discussion tool rather than a report.
Model scenarios, not forecasts
A single forecast invites debate about whether it is right. A set of scenarios moves the conversation to which conditions the business could tolerate, and where it would need to respond.
Design for handover
A model that cannot be maintained internally has a short useful life. Structure, labelling and documentation matter as much as the arithmetic.
