Advisory services

Senior expertise for healthcare problems that cross organisational boundaries.

Architecture methods are used to clarify decisions, make dependencies visible and leave usable assets behind, not to impose process for its own sake.

Services

Six complementary areas of practice.

Engagements are shaped around the problem rather than a fixed methodology. Several of these capabilities are commonly combined in the same piece of work.

Enterprise architecture

Make complex transformation decisions inspectable.

Capability models, target operating models, conceptual information models, architecture assurance, repository governance and transformation roadmaps.

  • Business capability models
  • Target operating models
  • Conceptual information models
  • Architecture assurance and decision records
  • ArchiMate, UML and BPMN modelling
  • Transformation roadmaps and dependency analysis
Health data architecture

Treat data as infrastructure, not an implementation by-product.

Data architecture work focuses on how meaning, governance and reuse are sustained across enterprise boundaries.

  • Enterprise data architecture
  • Metadata and catalogue strategy
  • Data standards policy
  • Semantic interoperability
  • Information governance
  • Data reuse and research architecture
Interoperability

Design around clinical flows and semantic obligations.

The focus is not simply whether systems exchange messages, but whether the information remains meaningful and usable for the intended clinical purpose.

  • HL7 FHIR and HL7 V2
  • IHE profiles and document exchange
  • Terminology and semantic mapping
  • Shared-care architecture
  • Cross-system information flows
  • Standards implementation analysis
Secure data environments

Build security and information governance into the architecture.

Experience includes controlled research infrastructure, ISO 27001 and security-sensitive healthcare and public-sector programmes.

  • Secure research environments
  • ISO 27001-aligned architecture
  • Information governance
  • Research data controls
  • Security-by-design
  • Secure programme assurance
AI-enabled architecture

Use AI to accelerate analysis without outsourcing judgement.

Generative AI can support source analysis, requirements synthesis, modelling and publication while retaining traceability and professional accountability.

  • Structured source analysis
  • AI-assisted modelling
  • Traceable architecture publication
  • Requirements synthesis
  • Assurance support
  • Healthcare AI assurance methods
Transformation readiness

Expose the gap between product implementation and organisational reality.

Readiness work connects pathways, dependencies, systems, information, operating models and implementation risk before those gaps become programme problems.

  • EPR readiness analysis
  • Clinical pathway assessment
  • Dependency mapping
  • Implementation risk
  • Transformation planning
  • Architecture decision support
How we work

Structured enough to assure. Agile enough to be useful.

1

Understand the problem

Establish the decision context, stakeholders, constraints, evidence and consequences of getting the answer wrong.

2

Make the system visible

Use capability, process, information and dependency models to expose otherwise hidden relationships.

3

Test coherence and risk

Examine whether strategy, data, technology, governance, workflow and delivery plans actually align.

4

Leave usable assets

Produce traceable models, catalogues, specifications, decision records and guidance that remain useful after the engagement.

Evidence through delivery

Experience spans national strategy, provider transformation, secure environments, shared records and research infrastructure.

The practice is intended for situations where architectural decisions need to survive contact with real programmes, operational constraints and governance.
