Result

A fractured reporting estate became one governed Power BI model, with every migrated number reconciled so the business trusted the move.

The challenge

Reporting was split across an aging BI tool, dozens of spreadsheets, and conflicting definitions, so the same metric meant three things and trust in the numbers was gone.

What we built

We inventoried the existing reports, rebuilt the important ones on a governed semantic model, reconciled every number to the legacy source, and retired the duplicates.

  • A governed semantic model replacing scattered report logic.
  • Rebuilt core reports reconciled to the legacy numbers.
  • Workspace structure, row-level security, and lineage.

Outcomes

  • One governed Power BI estate instead of tool sprawl.
  • Each measure defined once and reconciled to the old world.
  • Licensing and maintenance on a single platform.
