Decommissioning legacy without breaking the service
A staged approach to retiring legacy systems while keeping users - and auditors - comfortable.
Read article →The patterns in this article come from our work with large enterprises across regulated and fast-moving sectors. The aim is not to be exhaustive - it is to surface the handful of decisions we see making the biggest difference in practice.
1. Senior people, on the ground
Every CTO we speak to has been burned by the pyramid model: a senior partner sells the work, a junior team delivers it. The clearest signal of trust is putting the people who scope the work on the floor doing it.
2. Outcomes, with numbers
Engagements anchored in measurable outcomes - cost reduction, lead-time improvement, reduced incident volume, audit pass rates - are the ones that get renewed. “Capability uplift” is no longer enough on its own.
3. Honest trade-offs
Leaders are tired of consultancies that present every option as equally great. They want to be told what is fast, what is cheap, what is risky - and what we would not advise our own teams to do.
4. Knowledge transfer as a deliverable
The best engagements are designed to make themselves redundant. CTOs increasingly write that into the contract: explicit handover criteria, documentation standards, and pairing time with internal engineers.
