Resources & Insights
Left to right, the corridor never stops.
These articles are written for the people who have to decide whether to modernise, replace, or leave a system alone. No filler, no vendor pitch.
The archive
Twelve short guides. Each covers one decision that usually arrives before a build starts — how to assess it, how to stage it, what to write down, and when to leave the system alone.
Start here
Debt accumulates quietly. It shows up as slower releases, escalating incidents, and workarounds only one person understands. Start by mapping the systems, recording how often each one changes, and identifying where the risk sits. Rank the debt by cost rather than by how annoying it is.
Big-bang migrations fail more often than staged ones because they concentrate risk into a single window. A staged approach exposes data first, wraps the old system in an interface, migrates one bounded domain at a time, and retires the old path once traffic has moved. The trade-off is a longer timeline for far less operational risk.
Threat modelling before build, least-privilege access by default, secrets in a vault rather than a config file, dependency scanning in the pipeline, and audit logging that captures what matters.
A position
When a system will cost more to modernise than to replace, the honest advice is to say so. Every guide on this page exists to make that call easier to defend in a budget meeting.
What a partner is buying you
Regulated sectors
Compliance obligations, audit trails and change-freeze windows all lengthen the road from a working system to a modern one. These four sectors see the drag in different places.
Legacy batch systems sit behind change-advisory boards and financial-year freezes. Move a component without the audit trail following it and the migration stalls at the next review.
Clinical safety cases and records retention rules shape what can move and when. Data migration is rarely the technical problem; the mapping between old clinical codes and new ones usually is.
Shop-floor systems often have no upgrade path and cannot be stopped for a cutover window. The interface gets wrapped, opto-and-plc integrations stay in place, and the modernisation happens behind a stable façade.
Procurement is the longest stage, not the build. Spend reviews and framework agreements decide the schedule; the technical work is usually well understood before the contract is signed.
Read first. Rebuild second.
The guides on this page exist to give the visitor a defensible position before a build is commissioned — what the system actually costs, what a supplier is really offering, and what can wait.
