The challenge

Reports were running on a tangle of legacy models — slow, inconsistent across teams, and impossible to audit. The business needed one trusted layer.

Our approach

How we structured the work, end to end.

01
Designed a medallion architecture in Microsoft Fabric — Bronze for raw, Silver for conformed, Gold for business-ready.
02
Modelled the Gold semantic layer against the actual operational and financial decisions the business runs on.
03
Tuned refresh and Direct Lake for performance under real query load.
04
Migrated reports in waves with parallel running so no team was left without their numbers.

The architecture

From source to insight, in one governed flow.
