The useful outcome

A scenario model shows what follows from stated assumptions. It is useful for a decision even when it is not a prediction, provided the assumptions and formulas are easy to change.

An example request

This is an illustrative request, not a customer result or a promise that every connected service supports every step.

Build low, base and high scenarios from these assumptions. Show the formulas, keep unknowns separate and label the output as scenarios rather than a forecast.

A practical sequence

  • List the controllable assumptions
  • Use consistent units and time periods
  • Calculate scenarios and review the most influential inputs

What to check

Check that the model responds correctly when an assumption changes. Keep uncertainty in the inputs visible in the conclusions.

A mistake to avoid

Do not present a carefully formatted base case as the most likely future without a separate forecasting method.

Using Bris for this work

Analytical work starts with a question and a defined dataset. Bris can help organize sources, examine figures and prepare a reviewable output. Check the units, date window, missing values and formulas before using the result to make a decision.
