Lessons in Executive Leadership · 01 / 08

Leadership isn't about power. It's about responsibility.

Module 1 of what an Oxford Executive Leadership programme taught me — starting with the idea that reframed everything else.

When I started the first module, I expected to learn how to be a better leader. What I didn't expect was to spend the first week unlearning what I thought leadership was.

Here's the idea that did it, and it's deceptively simple: leadership is not about power. It's about responsibility.

I'd have nodded along to that sentence a year ago without really feeling it. But sitting with it properly changed how I show up. Because if leadership is power, then the goal is to accumulate it — more control, more say, more visibility. If leadership is responsibility, the goal is the opposite: to build so much clarity and confidence in the people around you that they don't need you hovering. One of those makes you the bottleneck. The other makes you a multiplier.

That reframe runs through everything else I took from this module. Here's what stayed with me.

There is no single "right" way to lead

One of the most freeing lessons was that effective leadership is contextual. The traits that make someone brilliant in a turnaround can make them exhausting in a steady-state team. Charisma helps in one setting and grates in another. Context, as one of the contributors put it, is king.

For years I quietly worried that I didn't lead like the confident, commanding archetype I'd absorbed early in my career. What this module made clear is that the archetype was never the point. The best leaders read the situation — where the organisation is in its lifecycle, what their people actually need right now — and adapt. Your job isn't to have one style. It's to know which one the moment calls for.

Effectiveness is decisions plus culture

When you strip leadership back, an enormous amount of your impact comes down to two things: the quality of your decisions, and the culture you build around you.

The decisions part I understood — engineers live and die by good calls. The culture part I'd underrated for years. You can make every technically correct decision and still lead a team that underperforms, because how people feel about the work shapes what they're willing to give it. Culture isn't the soft stuff you get to after the real work. It is the real work — the invisible foundation everything else is built on.

Clarity is a kindness

The line that lodged itself in my head: what you think you asked for is often not what people heard. I've lived this more times than I'd like to admit — a direction I was sure was crystal clear, understood five different ways.

The lesson isn't "communicate more." It's that being relentlessly, almost over-precisely clear is one of the kindest things a leader can do. Ambiguity feels efficient in the moment and costs you dearly later. Clarity takes more effort up front and saves everyone downstream. I now treat "am I actually being clear, or just brief?" as a question worth stopping for.

What I'm taking into practice

If Module 1 gave me one working principle, it's this: stop asking "how do I have more influence?" and start asking "how do I take more responsibility for the clarity, culture, and calls around me?" The influence turns out to be a by-product. It was never the thing to chase.

Next in the series: the job of the leader — envisioning and engaging. What a leader is actually for.

Which resonates most — that leadership is responsibility not power, or that clarity is a kindness? I'd love to know where you land.
