The 4th of June is Belbin Day: Marking the Legacy That Still Shapes Teams in the Age of AI

June 4th would have marked the 100th birthday of Dr Meredith Belbin, and we acknowledge the legacy that he has left for people, teams and leaders.

Whilst we sadly lost Meredith last year, the legacy he leaves behind continues to influence people, teams, leaders, educators, and organisations across the globe. He was a world-renowned researcher, academic and businessman. 

The founder of modern Team Role theory, his work fundamentally changed how organisations around the world think about teamwork, leadership, and human behaviour at work. His ideas and model are more relevant than ever in this Age of AI where humans will need to be more human than ever to thrive.

Few people have had such a lasting and practical impact on the way teams understand performance, collaboration, and the human dynamics that sit behind success.

Belbin’s groundbreaking work emerged from years of behavioural research, initially at Cambridge, then at Henley Management College, where he and his colleagues studied why some management teams consistently outperformed others. What they discovered was both simple and powerful: intelligence alone was not enough to create high-performing teams.

Teams succeeded when they achieved balance across different behavioural contributions.

From this research came the famous Belbin Team Role Model, identifying nine distinct behavioural Team Roles that people tend to display within teams.

Importantly, Belbin was never designed to place people into rigid personality “boxes.” Instead, it focused on observable workplace behaviour: how people contribute, communicate, solve problems, support others, challenge ideas, and help teams move forward.

This practical, behaviour-focused approach is one of the reasons Belbin remains so relevant today.

In modern organisations, technical skills can often be taught relatively quickly. What is far harder to replicate are the uniquely human elements of teamwork: judgement, trust, adaptability, emotional intelligence, collaboration, self-awareness, creativity, and the ability to work constructively with people who think differently.

These are precisely the kinds of dynamics Belbin’s work helps teams understand.

In an era increasingly shaped by AI, automation, and rapid change, the importance of these human capabilities is arguably becoming even greater. AI can process information at incredible speed. It can assist decision-making, analyse data, generate ideas, and automate many repetitive tasks. However, it still cannot fully replace the nuanced human behaviours that underpin effective teams and leadership.

The future of work is unlikely to belong purely to humans or purely to AI. More realistically, it will belong to organisations that learn how to combine technological capability with strong human collaboration.

This is where Belbin’s work continues to provide genuine value.

Dr Meredith Belbin’s work continues to remind us that successful teamwork is not simply about gathering talented people together. It is about understanding how people work together, where they complement each other, and how behavioural balance shapes collective performance.

As organisations continue navigating the opportunities and disruptions of the Age of AI, that lesson may be more important than ever.

One hundred years after his birth, Meredith Belbin’s ideas continue to help people better understand themselves, understand others, and build stronger, more effective teams for the future.
