At a time when organisations are accelerating AI adoption while struggling with legacy systems, cyber risk, and growing operational fragility, the real challenge is no longer technology—it’s leadership.

In this episode of Silicon In Focus, David Howell speaks with Dai Vaughan, Chief Technology Officer at Public Digital and editor of Shaping Technology for Transformation. Together, they explore why many organisations are trapped in layers of “digital geology,” where years of accumulated systems and decisions quietly slow progress and increase risk.

The conversation moves beyond technical debt to examine “leadership debt”—the habits, structures, and assumptions that prevent organisations from adapting at pace. From the illusion of control in discussions around digital sovereignty, to the practical realities of continuous untangling in large enterprises, this episode focuses on what it takes to build genuine organisational capacity—not just capability.

You’ll hear how leaders can strengthen adaptability as a core organisational muscle, create space for meaningful experimentation without adding to complexity, and develop the discipline to stop initiatives that no longer serve a strategic purpose.

Crucially, this episode reframes resilience—not as a theoretical exercise, but as something that must be actively rehearsed and embedded, long before disruption hits.

If your organisation is trying to modernise while carrying the weight of its past, this conversation offers a clear, practical lens for moving forward.
