Technology Consultation & Architecture Advisory

An independent read on an architecture, from the engineers who would otherwise have to build it.

We are asked most often to say what a system will do before anyone commits to it: whether a design holds at the next order of magnitude, what a platform is really worth in an acquisition, and which layer to rebuild first. The answer comes from measurement and from having built the layer in question, not from a reference model or a maturity grid.

What we build

H.1

Technology Consultation

A first read on the architecture, written by the engineer who would build it

Scoped engagements that produce a decision rather than a deck. We take the system as it is measured today, in latency, throughput, yield, uptime, and unit cost, locate the layer that sets the limit, and write down the options with their trade-offs and what each would cost to build. Delivered as a written architecture read with the measurement behind every claim, and the engineer who wrote it available to defend it.

H.2

Technical Due Diligence

What an engineering asset is worth, and what it will cost to keep

Independent assessment of a technology asset ahead of an investment, an acquisition, or a long contract. Covers the architecture and the scale at which it breaks, code and data ownership, third-party and licence exposure, security posture and incident history, key-person and knowledge concentration, infrastructure cost per unit of work, and a costed remediation plan in the sequence we would actually follow.

H.3

Modernization and Migration Strategy

A sequence that keeps the system running while it changes underneath

Plans for replacing load-bearing systems without an outage. Includes dependency and data-flow mapping of the estate as it actually runs, strangler-fig sequencing in reversible steps, dual-run and reconciliation that prove the new path before the old one is cut, data migration verified at every cut-over, rollback criteria written before the work starts, and a cost and risk model per step so the programme can stop at any point and still be ahead.

Architecture Assurance and Standards Compliance

Evidence that a design meets the standard it claims

Assurance for systems that must satisfy an external standard and prove it. Includes gap assessment against IEC 62443, NERC CIP, ISO 27001, and sector-specific regimes, controls mapped to the architecture rather than to a spreadsheet, evidence collection automated wherever the system can produce it, design review at each gate, and independent verification before an audit rather than after one.

Tell us where latency is costing you, from the die to the data center to the control room. An architect replies with a first read of the problem, not a sales deck.
