National Health Transformation

Context

UK public health environment delivering a large-scale CRM and ERP transformation. Privacy, operational continuity, and evidence-ready governance were treated as first-order requirements.

Role and mandate

Security and architecture analysis supporting programme delivery, risk management, and governance alignment across business processes, integrations, and access controls.

Architecture problem

Modernise core enterprise platforms while preserving confidentiality and integrity of sensitive data, maintaining availability, and ensuring auditability across transformed workflows.

Constraints

• High-sensitivity data requiring strict access control and demonstrable audit trails.
• Complex stakeholder environment and constrained change windows.
• Legacy integrations and operational dependencies limiting migration options.

Decisions and trade-offs

• Controls designed for enforceability and evidence generation, not documentation alone.
• Phased adoption prioritised by operational criticality and risk rather than application boundaries.
• Governance clarified through explicit separation of programme controls and platform controls.

Outcomes

• Reduced delivery risk through early clarity on control ownership and evidence pathways.
• Improved auditability and access governance for transformed enterprise workflows.
• Security posture aligned to public-sector regulatory and operational expectations.
