Budgeting & Forecasting
A forecast is a decision tool, not a corporate ritual. I ground every budget and forecast in variance history and driver behavior — so the plan reflects real trends, not optimistic assumptions, and it gets updated as the business moves.
The Workflow — How I Approach It
Ground it in variance history
Start from what actually happened — actuals and their drivers — not from a blank target.
Separate the cost behavior
Fixed, variable, and discretionary lines behave differently — model them differently.
Model scenarios and sensitivities
Show the plan under base, downside, and upside — with the drivers that move each.
Pressure-test with the owners
Validate the assumptions with the business owners who will be held to the number.
Update monthly, not annually
Roll the forecast with each close — a forecast that waits a year is a museum piece.
My Operating View — The 2 Cents
Most budgets are born optimistic and die unread. My 2 cents: the budget is a promise, and the forecast is its honest update. If history keeps contradicting the plan, the plan is wrong — not the month. Forecasts should move monthly, with the close.
What Worked & What Didn’t
What Worked
- Forecasts informed by variance history — tighter error, cycle after cycle.
- Monthly forecast rolls kept the plan alive instead of stale.
What Didn’t
- Optimistic assumptions with no historical anchor — missed by design.
- Annual-only planning — six months in, the plan was fiction.
