Cut here first: sequencing your way out of legacy

Theme

Every organisation accumulates legacy. Sometimes it’s deliberate and prudent; more often it’s the quiet cost of moving fast. Left too long, the ability to make safe, swift change drops rapidly — and by the time that’s obvious, the business can’t afford to stop and fix it.

Drawing on twenty years of helping organisations escape architectures that are holding them back, this session makes the case that the hardest question isn’t how to cut — it’s knowing where to cut first. Using a practical two-axis framework and stories of escapes that worked, and one that didn’t, you’ll leave with a model for sequencing large-scale change that engineers and leaders can use together.

Participant takeaways:

• A broadened definition of legacy that makes the problem recognisable across industries and team sizes, not just in classic monolith scenarios.
• A two-axis prioritisation framework for deciding where to act first, grounded in business criticality rather than technical convenience.
• An understanding of the “pave the way” sequencing pattern — when the right first move isn’t the highest-value extraction, but the one that makes the highest-value extraction possible.
• A priority ordering — safety and stability, customer scale, change velocity, product innovation — that creates shared language between engineering and business leadership
• Recognition of the cultural layer: why ownership, incentives and ‘pits of success’ matter as much as architecture patterns
