Assumption modeling for consistent scenarios
Forecasts drift when assumptions aren’t explicit. We build an assumption framework with owners, ranges, and definitions so teams can compare scenarios consistently.
Service overview
We help teams define assumptions as a first-class part of planning: what’s being assumed, who owns it, and how it’s reviewed. The output is a consistent assumptions table and scenario mechanism that keeps comparisons meaningful over time.
Definitions
What the driver means and how it’s measured.
Ownership
Who updates each assumption and when.
Comparability
Scenarios that can be compared month to month.
Common problems solved
- Scenarios can’t be compared because assumptions changed silently
- Inputs live in multiple tabs and aren’t clearly owned
- Definitions drift across teams and reports
- Forecast reviews focus on outputs, not drivers
What implementation includes
Assumptions framework
- Assumptions table with owners, ranges, and notes
- Definition and measurement guidance
- Scenario structure for consistent comparisons
Cadence + documentation
- Monthly assumptions review checklist
- Versioning approach for changes over time
- Templates for explaining assumption updates
Typical outcomes
More consistency
Scenarios remain comparable across time.
Cleaner reviews
Teams discuss drivers instead of spreadsheet logic.
Better ownership
Inputs have clear owners and refresh cadence.
Decision-support and unlicensed services
This engagement focuses on clarifying and modeling assumptions for internal planning. We explain and model; we do not provide tax, legal, audit/assurance, or investment advice, and we do not recommend regulated actions.
