Consolidating a fragmented application estate through staged modernisation.

The challenge

Users were moving between disconnected portals

The organisation relied on several portals and applications. Handoffs between them were difficult to follow, and the fragmented environment made errors, work tracking and communication across systems harder to manage.

Replacing everything at once would have introduced unnecessary operational risk. The more useful starting point was to create a coherent user entry point, then modernise the parts of the estate that would benefit from change.

A staged route through the estate

The applications were brought behind a shared portal using a micro-frontend approach. Selected screens and modules were rewritten; other applications remained in place where that was the safer practical choice. This let the organisation move users towards one experience without requiring a big-bang migration.

Backend capabilities were then centralised and separated into services with clearer boundaries, so components could operate more independently and the wider system became easier to maintain and govern.

Delivered and handed over

The solution was completed, released to production and handed over to the customer. The customer accepted the operational improvements, and performance measures were used to demonstrate them. No numerical result is published because no specific metric or permission to disclose one is part of this brief.
