Every report tells a different story
The same indicator is calculated from different sources or with different rules.

I build BI from indicator logic through to the dashboard. We agree what a number means and how it is calculated before deciding how it should look on screen.

Critical calculations live in manual files and refreshing a report depends on one person.
The screen is full of metrics, yet leadership still needs a separate explanation before acting.
The work starts with the indicator, not the chart. Source, formula, period, grain, owner and quality checks come first. That is what makes BI stable.
Agree what decision the report supports and who uses it.
Set formulas, sources, time periods and checks.
Replace manual joins with a stable analytical model.
Keep only what helps someone see status, deviation and the next action.
