Approach

Architecture as a decision discipline

We use enterprise architecture so organisations can make durable ICT choices — with named owners, explicit trade-offs, and artefacts programs can spend against. Method is aligned to common EA practice; we size to the decision that is blocked.

Context before tooling

Every engagement starts with how your organisation actually decides and delivers — stakeholders, constraints, and the operating reality that architecture must serve. Products and platforms are answers; we start with the question.

Not every engagement runs all three phases. We propose a shape against the blocked decision, then adjust as evidence arrives — without inventing urgency or inflating scope.

Stakeholders, constraints, and architecture decisions in context

Engagement phases

Each phase has a trigger, inputs, and outputs. That keeps architecture decidable and handover honest.

01

Orient

Trigger
Decisions are stuck, the estate is opaque, or AI/ICT appetite is outrunning governance.
Inputs
Sponsor brief, stakeholder access, existing strategy / risk / architecture artefacts, and a clear statement of what is blocked.
Outputs
Current-state pack, gap register, decision-rights sketch, and a shortlist of blocked choices ready for Shape.

02

Shape

Trigger
You need target options, principles, or a roadmap that PMO and operations can fund.
Inputs
Agreed gaps and decision shortlist from Orient (or equivalent client material).
Outputs
Target skeleton, architecture principles, integration patterns, sequenced roadmap, and explicit trade-offs.

03

Deliver & embed

Trigger
Direction is agreed and the next step is live change or lasting internal practice.
Inputs
Agreed target, principles, and governance path; named client counterparts for coaching or delivery.
Outputs
Solution architecture, transition plans, coaching cadence, ADRs in use, and named owners for ongoing artefacts.

Artefacts we favour

Thin, binding artefacts over large slide inventories. Exact set depends on the engagement.

  • Capability maps

    Shared language for demand, portfolio, and target discussion.

  • Decision rights

    Who decides what — bound to PMO and change paths.

  • Architecture principles

    Constraints leaders and delivery can actually apply.

  • ADRs

    Decision records programs consume, not shelf-ware.

  • Integration patterns

    How new work meets the live estate.

  • Roadmaps

    Sequenced change with explicit trade-offs and risk.

Principles we work by

  • Context before tooling

    Start with the decision and the constraint — then choose platforms.

  • Senior attention, boutique scale

    You work with people who own the advice, not a revolving cast of juniors.

  • Evidence over marketing claims

    No inflated outcomes, fabricated case studies, or generic AI hype on this site or in the room.

  • Leave capability behind

    Success means your teams can continue the work without us in the room.
