MODERNISATION
Legacy modernisation
Strangler patterns and data products that unlock capability without friction in the roadmap.
What it solves
Big-bang replacements fail under operational reality; meanwhile technical debt compounds. Programmes need defensible sequencing and measurable milestones.
How it works
- 1Assess coupling, data gravity, and regulatory constraints to sequence cuts.
- 2Define target boundaries with migration guardrails and recovery objectives.
- 3Deliver thin slices that reduce risk while proving value to sponsors.
- 4Institute engineering standards: testing, observability, and platform automation.
Where it applies
- Core-adjacent servicing and payments estates
- Policy admin and claims platforms in insurance
- Member and employer experiences in retirement and benefits
Business outcomes
- — Reduced cost-to-change in the domains that matter most
- — Improved reliability and performance on customer-critical paths
- — A multi-year roadmap that survives leadership and vendor churn
Delivering strategic strangler patterns that de-risk the transition from technical debt to modern engineering capability.
