Definitions and evidence

Keep observations, assumptions and calculated results distinct.

Observed information
A fact reported by an identified source, with its original scope and limitations.
Planning assumption
An input chosen for a specific model case. It is not a guarantee of future results.
Calculated output
A result produced by formulas from the inputs and calculation structure.
Operating format
A defined way of delivering goods or services, with a paying unit and a capacity boundary.

How to use an assumption

Check its unit, period, currency, geography and tax treatment. Replace it with evidence for your own intended operation, then review the linked results.
