Driver-based planning

Building a financial plan from operational drivers, such as units sold or headcount, rather than top-down growth assumptions.

Driver-based planning builds a financial model out of the operational variables that actually cause revenue and costs to move, things like units sold, price per unit, headcount, or conversion rate, and links them together with formulas so the financial outputs are calculated, not typed in directly. Revenue becomes "sales reps x quota attainment x average deal size" rather than a single growth-rate assumption applied to last year's total.

This differs from a top-down plan, where someone sets a target such as "grow revenue 20%" and spreads it across the business without modeling the operational activity needed to hit it. Driver-based models are usually the engine behind a rolling forecast or scenario modeling exercise, since changing one driver, such as headcount from headcount planning, automatically recalculates every downstream number.

It matters because it makes plans testable and explainable: when actuals diverge from plan, variance analysis can point to which driver moved, not just that the total was off. The common pitfall is building a driver model with too many drivers to maintain, or drivers that are not actually independent of one another, which makes the model fragile and its outputs misleadingly precise.
