Leadership That Makes A Difference

After more than 30 years in the U.S. Army, with assignments ranging from the Pentagon, the American embassy in Beijing, and the front lines in Iraq and Afghanistan, Mark O’Neill has seen what effective leadership truly requires. At the Kvalitetsmässan conference, he shares his insights on how to build trust, create shared values, and shape strong, cohesive teams.

When Mark O’Neill first entered the military in the 1970s, he didn’t plan to make a career out of it. But the journey from foot soldier to diplomatic assignments, from the battlefield to the Pentagon, and later to leadership development consultancy turned out to be both long and enlightening.

Today, he helps companies and organizations build strong teams, foster good relationships, and develop sustainable leadership.

– Leadership is a human process, It’s not about being the expert – it’s about listening, learning, reflecting, and constantly improving, he says.

Trust – The Foundation of Strong Leadership

For Mark O’Neill, trust is at the core of good leadership. It’s the foundation upon which all functioning relationships, collaboration, and decisions rest, and it is built not with words, but with actions.

– A good leader is someone people can rely on, in both good times and bad. If your team doesn’t trust you as a leader, or trust each other, it doesn’t matter how good your strategy is. Everything will fall apart, O’Neill says.

Trust shapes the culture of an organization. And it’s the culture that determines whether you can manage crises, learn from mistakes, and continue to evolve. That’s why leaders must create an environment where honesty, accountability, and learning are encouraged, and where it’s okay to fail and grow from the experience.

– We used to hold after-action reviews after every mission. We asked questions like: What happened? What did we learn? What will we do differently next time? That builds a safe culture where people take responsibility and where trust becomes a natural part of the work.

Adaptive Leadership

Good leadership also means being able to adapt to people, contexts, and circumstances. One of O’Neill’s most challenging and educational assignments was leading logistics for the international coalition in Afghanistan. Over 15,000 people from different countries, languages, and cultures had to work together. Structure and coordination weren’t enough, leadership had to be shaped by the situation.

– In a context like that, you have to listen more than you talk. It’s not just about language, it’s about understanding how leadership is perceived in different places, how criticism is received, and the nuances that build or break trust.

He emphasizes the importance of understanding your own background while also taking in others’ perspectives, and then adjusting your pace and approach accordingly. Without that understanding, you risk creating distance instead of trust.

When the Plan Fails – Leadership Is Forged

Leadership is truly tested in the hardest moments, O’Neill believes. When the unexpected happens and the original plan falls apart, you need the ability to see clearly through chaos and find new ways forward.

– Few plans survive first contact with reality. That’s why leaders need to adapt quickly. It takes courage to make decisions without having all the information, and humility to listen to your team and adjust course, says Mark O’Neill.

Humility, in particular, is a central trait of modern leaders. A common trap is believing you need to have all the answers, but that’s not always necessary.

– There are good ideas everywhere in an organization. The leader’s job isn’t to have the solution, but to create the conditions for solutions to emerge collectively, says O’Neill.

Trust Is Built in the Everyday

According to Mark O’Neill, one of the greatest challenges facing today’s leaders is maintaining and building trust — the capital upon which all leadership rests. And trust isn’t formed through titles or strategies, but through a leader’s everyday actions, especially under pressure.

– Ethics and trust go hand in hand. You need to show that you act with honesty and integrity, otherwise, you lose trust. And without trust, you have nothing, says O’Neill.

He believes that good leadership requires clear values, attentiveness, and a genuine understanding of people, whether in military operations or civilian organizations.

– Leadership is about responsibility, openness, and respect. A good leader listens, shows care, and fosters an understanding of the bigger picture.

But organizing and directing isn’t enough — companies also need to actively develop their leaders. It’s people, not structures, that drive an organization forward.

– Many invest in systems but forget the people who make them work. Even though leadership development takes time, it’s worth every minute.

Mark O’Neill at Kvalitetsmässan 2025

When Mark O’Neill steps onto the stage at Kvalitetsmässan 2025, his message will be clear: leadership is, at its core, about people.

Drawing from his military experience, he’ll share concrete advice on how to build strong teams, create shared values, and lead with clarity in a constantly changing world.

– I hope participants take away that leadership is about people, about building relationships, creating culture, and making it possible for others to grow. And that it’s never too late to become a better leader.
