A rebuilt data platform cut report times from hours to under five seconds
A US mutual insurer's data platform, rebuilt on Microsoft Fabric, now assembles underwriting and claims numbers automatically, so reports that once took hours answer in under five seconds.
The Opportunity
An earlier round of modernization had left this US mutual insurer's data spread across old platforms and new ones, each holding its own partial version of the numbers that mattered most: underwriting margin, loss trends, claims performance. Nobody had decided this on purpose. It's what happens when systems get upgraded in phases and nobody goes back to reconcile what's left behind.
The practical effect was a company running on hand built reports. Someone would pull data from one system, someone else from another, and a meeting meant to review performance would open with ten minutes of arguing over whose number was right. The cost wasn't just the hours spent assembling reports, it was decisions slowed down by a numbers problem that had nothing to do with the business itself.
The Transformation
The data platform was rebuilt on Microsoft Fabric, changing how data moves through it. Instead of pipelines built and maintained by hand for every report, data flows automatically from source systems into one governed store, structured against a single standard set of definitions for underwriting margin, loss ratio, and claims performance. There's no longer a version from the old system and a version from the new one, there's one number, and everyone reports from it.
Speed came from the same decision. Fabric's lakehouse architecture lets reports query the governed data directly instead of waiting on nightly exports and imports between systems, which is why a report that used to take hours now comes back in under five seconds. The team didn't build a faster way to pull the same fragmented data. They removed the fragmentation, and speed followed.
One Set of Numbers, Assembled Automatically
Data now flows from every source system into a single governed store on its own, replacing the manual consolidation that used to sit between raw data and a usable report. The whole business finally reports from the same numbers.
Rebuilt on Microsoft Fabric
Warehousing, lakehouse, and reporting now run on one unified platform instead of a patchwork of tools left over from earlier modernization phases, feeding the same standardized store automatically, every time.
Answers in Under Five Seconds
Reports query the governed data directly instead of waiting on batch exports between systems. What used to take hours to assemble by hand now returns an answer before the question is finished being asked.
Half the Effort to Keep It Running
Consolidating onto one platform retired the duplicate pipelines and tooling that used to need constant upkeep, cutting maintenance effort in half and freeing the team from firefighting data instead of using it.
