Enterprise Architecture

Design the enterprise to adapt.

Our architectural perspective connects business intent, trusted enterprise knowledge and controlled AI execution across the existing estate. The aim is measurable commercial value, clearer operational control and an organisation that can change with confidence.

  • Business-led design
  • Customer-controlled deployment
  • Measurable outcomes
The architectural problem

Find the dependencies that make change difficult.

Over time, business knowledge and operational decisions spread across applications, interfaces, data pipelines, documents and manual work. No single change is hard in isolation; the difficulty lies in the dependencies between them.

Our practical response is to identify the dependencies affecting a chosen business outcome, clarify who owns them and introduce appropriate boundaries. An existing system can remain valuable — replacement should follow a business and engineering assessment, not precede it.

Applications

Rules and workflows embedded in individual systems.

Integrations

Dependencies that make changes difficult to isolate.

Information

Inconsistent definitions, uncertain ownership and evidence that is difficult to trace.

The principles

The principles behind an adaptive enterprise.

Fourteen principles we apply, balanced across commercial value, speed of change, reliability and governance. They are established practice expressed as our perspective — expand each for the design decision, why it matters and where it can go wrong.

The architecture model

How intent becomes accountable action.

An original reference model showing how a request moves from intent to an authorised change in enterprise systems. It is an architectural model, not a description of one implemented platform shared by all our offerings. Select any component for detail.

Text description of the diagram
  1. Business intent and experience — The customer request, employee task or operational objective.
  2. Decision services — Rules, workflows, retrieval and AI capabilities selected for the task.
  3. Authorisation and policy — Permissions, evidence requirements, business limits and human approval.
  4. Controlled execution — Approved tools, application interfaces and orchestrated operations.
  5. Enterprise systems — Operational applications and authoritative business records.

Intent is passed to decision services, which read governed data and business knowledge and propose an action. Authorisation and policy approve, refuse or route the proposal to an accountable person. Only authorised actions reach controlled execution, which writes to enterprise systems through governed interfaces. Enterprise systems return updated state and events. Outcomes feed evaluation and business measurement. Identity, security, privacy and observability apply across every layer, supported by shared infrastructure.

Make it concrete

Follow one decision through the architecture.

Three illustrative scenarios. They contain no customer names, amounts or performance results.

Illustrative
  1. 1. Intent

    A customer contacts us to report that a service is not working.

  2. 2. Evidence

    Retrieve the relevant customer record, service configuration and recent service events.

  3. 3. Recommendation

    Propose a response — a known remedy, a diagnostic step or an engineer booking.

  4. 4. Control

    Check the customer’s identity and that the proposed operation is permitted for this case.

  5. 5. Action or handover

    Perform the approved operation through a defined interface, or hand over to a person with the context attached.

  6. 6. Measurement

    Record resolution, time to resolution and whether a handover was needed.

Exception path: If service records are incomplete or a system is unavailable, do not guess: explain the delay to the customer and hand over to a person with what is known.
Architectural judgement

The decisions that require judgement.

Architecture is a series of conscious trade-offs. These are the ones we see most often, and the criteria that shape our recommendation.

Shared definitions
vs Local domain ownership
Share definitions that cross boundaries, such as customer or contract; leave domain-specific detail with its owners.
Reusable components
vs Excessive abstraction
Extract a component once two or more real uses exist and their needs are understood.
Automation speed
vs Approval requirements
Reversibility, financial impact and customer effect determine where approval is required.
Supplier portability
vs Specialised capabilities
Accept specialisation where it is material to the outcome; keep contracts clear so it can be revisited.
Resilience
vs Operating cost
Match resilience to the business impact of failure, not to a uniform standard.
Incremental modernisation
vs Temporary coexistence
Plan the coexistence period, its cost and the conditions for retiring the old path.
A short readiness reflection

Six questions to ask before you build.

Ungated and self-reported. No information is collected.

Is the business outcome defined and owned?
Are the necessary records and quality requirements understood?
Are relevant business rules maintained?
Can actions be authorised and constrained?
Can failures be detected and recovered?
Is a team accountable for the capability in production?
Measure architectural value

Measures that show whether the architecture is working.

Definitions, not statistics. Each engagement sets its own baseline.

Time to implement a business change
Elapsed time from an agreed change request to its release in production.
Cost per successfully completed outcome
Total operating cost for the journey divided by outcomes completed without rework.
Exception and rework rates
Share of cases routed to a person, and share needing correction afterwards.
Recovery performance
Time to detect and recover from failures, and cases left in an inconsistent state.
Reuse of validated capabilities
Number of journeys using an already evaluated rule, interface or service.
Customer outcomes
Resolution, effort and satisfaction measures for the journey concerned.
Realised cost reduction
Cost changes evidenced in budgets or contracts, not estimated time saved.
Revenue contribution
Revenue attributed only where the attribution method is supportable.

Staff time released becomes a financial saving only when a corresponding cost change is evidenced — for example, a reduced contract, avoided hire or reallocated budget.
