Architecture and technical decisions for complex programmes.
Some technology decisions are cheap to change. Others define what a system can do for the next decade. We help organisations make the second kind deliberately — assessing the existing estate, designing realistic target architectures and sequencing change under real constraints — so high-impact decisions are made before they become high-cost implementation decisions.
When organisations call us
- A major programme needs a target architecture, and the current direction is a collection of team-level decisions.
- Multiple systems and teams are evolving without a coherent technical direction.
- A significant platform or architecture change is under evaluation and the options are genuinely unclear.
- Technical debt has stopped being an engineering complaint and become a delivery constraint.
- A build, buy or integrate decision carries more risk than anyone wants to own alone.
- AI or another emerging technology is being introduced into an existing estate.
What we do
- Architecture assessment of existing systems — structure, dependencies, coupling, operational risk.
- Target and solution architecture with an explicit path from the current state.
- Integration architecture across systems, teams and external platforms.
- Technology option analysis and build/buy/integrate evaluation against real constraints.
- Architecture decision records that make the reasoning inspectable, not just the outcome.
- Migration sequencing, non-functional requirements and technical governance for the change.
Typical outputs
- Architecture assessment report
- Target architecture
- Architecture decision records (ADRs)
- Technology option analysis
- Build/buy/integrate evaluation
- Technical roadmap with migration sequencing
- Risk register with mitigations
- Technical governance model
How we approach it
We start from the system that exists, not the diagram we would prefer. Constraints, dependencies and operational reality shape the options; decisions are recorded with their reasoning; and the architecture stays close enough to implementation to remain honest about cost and sequencing.
