AI is an obvious example. Not because of the models themselves, but because of what they force us to confront: governance, responsibility, decision-making, skills, trust. AI is not a feature. It’s a shift in how organizations think and act. Treating it as anything smaller is comforting, and usually wrong.

But AI isn’t the only big one. Enterprise transformation is another. If you’ve ever tried to align platforms, identity, cybersecurity, data, digital workplace, ERP, and integration across countries and cultures, you know it’s more than a technical exercise. It’s an organizational one. It touches power, habits, language, and sometimes egos. It’s rarely clean. It’s always consequential.

That’s where the word one matters. Not as in “one size fits all”, but as in coherence. One enterprise that still allows diversity. One platform strategy that doesn’t kill local intelligence. One governance rhythm that people actually understand. One shared language between technology and business, so conversations stop sounding like parallel monologues. This is, in my experience, where many transformations struggle. Not because people lack intelligence or goodwill, but because fragmentation slowly becomes the default. The big one, for me, is the effort to turn that fragmentation back into something that behaves like a system.

There’s another meaning too, slightly less comfortable. The big one is also the shock you prepare for. The cyber incident that will happen one day. The outage you hope never occurs. The acquisition that suddenly doubles complexity. The global shift that renders last year’s plans obsolete.

I’ve learned that resilience is not about heroics. It’s about design. Calm, boring, intentional design. Clear roles. Clear decisions. Architectures and organizations that bend instead of snapping. When things go wrong, the real question is never “who is to blame?”, but “did we build this to survive reality?”

That’s also why I often think in terms of what call the dandelion model. Multiple hub-and-spoke. Fast. Resilient. Secure. Strong roots and a solid core, but light, adaptable structures at the edges. A system that holds together without being rigid. Technology, data, processes, and people working as a living organism, not a concrete monument.
