TECHNOLOGY ARCHITECTURE REVIEW
Independent Technology Architecture Review
An evidence-based view of whether your platform can support where the business is going, what is putting it at risk, and what to change first.
What is a technology architecture review?
A technology architecture review is an independent assessment of how a platform is designed, built and operated, and whether it can support the organisation’s plans. It examines application structure, infrastructure, data, integration, security, reliability, technical debt and cost, then separates the risks that matter commercially from those that do not, and sets out a prioritised plan for modernisation.
THE PROBLEM
When the platform starts shaping the strategy
Architecture problems rarely announce themselves. They appear as slower releases, rising cloud bills, incidents nobody can fully explain and features that take three times longer than they should. By the time the business notices, the architecture is already constraining the strategy.
An independent review gives leadership a clear picture: what is sound, what is fragile, what is expensive, and which changes will make the most difference.
WHO IT IS FOR
This is a good fit if you are
- Leadership teams whose growth plans depend on the platform
- CTOs and engineering leaders who want an external view before a major investment
- Organisations inheriting a platform after an acquisition or a change of partner
- Businesses deciding whether to modernise or replace
It is probably not the right fit if
- The system in question is primarily an AI or LLM application. The AI Architecture Review goes deeper there.
- The review is part of an investment or acquisition. Technical Due Diligence is structured for that decision.
TYPICAL TRIGGERS
When organisations usually ask for this
- Scaling problems or recurring incidents
- Cloud costs rising faster than usage
- A modernise-or-replace decision
- Slowing delivery and growing technical debt
- Preparing the platform for AI
- A new CTO wanting an objective baseline
THE PRACTICAL CTO ARCHITECTURE REVIEW FRAMEWORK
Five questions every
architecture must answer.
01 →
Fit
Does the architecture support the business model and plans for the next two to three years?
02 →
Change
How safely and quickly can the system be changed: modularity, testing, deployment and debt?
03 →
Run
How reliably and efficiently does it operate: resilience, observability, performance and cost?
04 →
Protect
How well are data, access and the supply chain secured?
05
Evolve
What would it take to add AI, new markets or new products?

ENGAGEMENT
How the review works
01 →
Frame
Agree the business questions the review must answer and the systems in scope.
02 →
Inspect
Architecture documentation, code, infrastructure, pipelines, monitoring and cost data, plus interviews with the team.
03 →
Assess
Evaluate each area against the business plan, not against an abstract ideal.
04 →
Prioritise
Separate critical risks from improvements, and sequence them.
05
Present
A leadership read-out and a technical read-out, with the written report.
DECISION CRITERIA
Modernise, refactor or replace?
- Refactor when the architecture fits the business and the problems are local.
- Modernise incrementally when the core model is sound but key components limit change or scale.
- Replace only when the cost of change in the current system consistently exceeds the cost and risk of rebuilding, and you can run both during the transition.
EXPERIENCE
What informs this work
I am Chief Technology & AI Officer at Webskitters, which I co-founded in 2010. My day-to-day work is technology and AI strategy, architecture and engineering leadership, so the judgement offered here is formed by operating responsibility rather than observation.
The frameworks on this page are published openly on The Practical CTO, so you can judge the thinking before we speak. Where a decision leads to implementation, Webskitters can deliver it, but the advice stays independent of who builds.
QUESTIONS
Frequently asked questions
What access do you need for an architecture review?
Typically architecture documentation, read access to code repositories, infrastructure and monitoring views, cost reports, and time with key engineers. Access is agreed in advance and kept to what the review needs.
Is this a code review?
Code is one input, sampled to test how the architecture is actually implemented. The review is broader: it covers infrastructure, operations, security, cost and how well the platform fits the business plan.
Will the review tell us whether to rebuild?
It will give a clear recommendation on refactoring, incremental modernisation or replacement, with the reasoning and the risks of each. Rebuilds are recommended only when the evidence supports them.
Can our team act on the findings without you?
Yes. The report is written so your team or partner can act on it. Follow-up support is available if you want it, but it is not assumed.
