Investment, inflation, uncertainty: bring each future flow back to today's value.

Criteria cross (value, return, risk, order of magnitude); figures inform without replacing judgment.

A wrong model gives wrong results with confidence; structuring and checking stays essential.
4.5 · Application
12. Rachid keeps his dashboard in Excel. When to consider Power BI?
Start with Excel (PivotTables, charts), migrate to Power BI if manual load or interactivity requires it.
