A clear architecture direction and roadmap for a finance company after a merger

The challenge

The client is an Australian finance company providing digital solutions that make complex financial interactions simpler and more secure for its customers. It operates in a highly competitive, regulated market, and was focused on building the technology foundations for its next phase of growth.

After a significant merger, its tightly coupled core platform and accumulated customisations had left critical technical debt, and stability and scalability limits that threatened future growth.

The company needed a clear vision for its future-state architecture and an actionable roadmap from a complex, constrained technology environment to a scalable, domain-aligned structure. Success depended on understanding the existing environment quickly, and on turning a complex transformation into a clear path that technical teams, the wider business and senior leadership could all follow.

Our approach

The company chose Interfuze for its expertise in architecture strategy, roadmapping and Azure cloud.

We worked in an agile way with a regular presence on site to keep stakeholders engaged and aligned: structured workshops with key stakeholders, regular stand-ups to keep momentum, and fortnightly showcases and status reports for transparency. The approach balanced technical rigour with business context, so the recommendations were technically sound and strategically relevant.

We delivered a layered architecture strategy: an architecture vision for the future state, architecture principles to guide decisions, and a target-state architecture restructured around domain-aligned teams and core business capabilities. An implementation roadmap sequenced the initiatives with their dependencies, milestones, timelines and operating model recommendations, and visual diagrams across the data, application and technology domains showed both today's constraints and the target capabilities, written for technical and business audiences alike.

The outcome

The company has a much clearer view of its architecture, with detailed pictures of its current and target states across the technology landscape. The transition roadmap gives leadership a clear view of the transformation, to prioritise investment and allocate resources.

The foundation positions the company to improve platform stability and scalability, strengthen compliance readiness and become more agile.
