Platform modernisation for a specialist lender targeting £40m+ in cumulative benefits
Technology legacy hampering business growth
Rapid customer and volume growth were running into the limits of a heavily customised, home grown application estate. Years of point solutions and bespoke integrations created a brittle technology landscape where change was slow, risky and expensive. Regulatory and operational demands were rising, but the underlying architecture lacked the scalability, resilience and modularity to keep pace.
The client needed an actionable technology modernisation roadmap - one that would move from a legacy monolith towards a modern platform ecosystem, remove growth constraints, and provide a clear investment case tied to achievable benefits.
Technology capability appraisal and modernisation roadmap
We conducted a top-to-bottom assessment across business capabilities, current state systems and interfaces, identifying hotspots for risk, technical debt and change pinch-points. Through collaborative workshops we created a capability baseline and defined the target state architecture - decoupled domains, standardised interfaces, and platform based components to support future products and volumes.
We also delivered a full investment case aligned to budget forecasts, with options and phasing.
Finally, we built a 3-year implementation and transition roadmap structured around phased delivery to minimise execution risk and accelerate time to value, with risk analysis and mitigation strategies embedded.
Improved Efficiency
- £40m+ estimated net cumulative benefits over 5 years, tied to phased delivery milestones and portfolio funding gates
- Clear line of sight from strategy to delivery: capability led target architecture, investment case and roadmap governing the move from legacy estate to a platform ecosystem
- Growth unlocked with lower change cost: reduced brittleness, improved scalability and faster path from demand to delivery
