How long should a good board member stay in the room? In this episode of The Boardroom Path, host Ralph Grayson speaks with Professor Alex Hill, Professor of Operations Management at Kingston Business School and co-founder of the Centre for High Performance, about what keeps organisations successful across generations rather than quarters. The timing matters. Russell Reynolds Associates recorded 234 chief executive departures globally in 2025, a 16% rise on the year before, with the average tenure of outgoing CEOs falling to 7.1 years, according to its Global CEO Turnover Index. Alex's own study of 440 school leaders found that the ones who built lasting improvement, the architects, almost lost their jobs at the end of year two, while the cost cutters he calls surgeons collected the accolades and moved on. The conversation covers the stable core and disruptive edge of enduring institutions, why about a quarter of a board should hold a decade of organisational memory but few should stay beyond fifteen years, and the one hard number Alex trusts as a predictor of long-term success.

He began his career in engineering, spending ten years across divisions of the Smiths Group and managing factories and larger parts of the business before moving into research and teaching. Over more than twenty years he has studied high-performing organisations across elite sport, education, the arts, healthcare, technology, financial services and the military, including Olympic teams, British Cycling, the New Zealand All Blacks, NASA, Eton College and the Royal Marines. He is the author of Centennials, drawn from a thirteen-year study of institutions that have stayed relevant for more than a century, and a Harvard Business Review contributor whose research on architect leaders challenged the appeal of the heroic turnaround chief executive.

Episode Insights: High performance is high stress, because getting it right and getting it wrong both have consequences, and that pressure exposes how individuals and teams really behave.Enduring organisations hold a stable core of purpose and stewardship alongside a disruptive edge of people who challenge, provoke and push for change.Collective experience of the organisation itself is one of the better predictors of long-term success, which argues for staggered board tenure rather than fixed uniform terms.Architect leaders rebuild for the long term and usually face a confidence crisis in year two, while surgeons cut costs, take the credit and leave the organisation weaker.The vitality index, the share of sales from products developed in the last two years, gives boards a hard number for whether the business will still be relevant in future.Action Points: Map the tenure profile of your board: Plot when each director joined and when each is due to leave. Look for clusters where most of the organisational memory arrives or departs together, since that is where future risk sits. Aim for overlapping terms so knowledge is handed over rather than lost in one go.Run your own vitality index: Ask management what share of this year's revenue comes from products, services or clients started in the last two years. Set the target from how fast your market moves, from a third for slow-moving sectors to nearly all of it for fast ones. Track it beside profit so cost cutting cannot disguise a stalled business.Decide what you are hiring a chief executive to do: Agree at the outset whether this is a turnaround or a long-term rebuild, because the two need different people and different timeframes. Write down what good looks like in years one and two for a rebuild. That record protects an architect from being judged on a surgeon's scorecard.Rehearse the pressure before it arrives: Put realistic scenarios in front of the executive team and work through each eventuality. The purpose is to keep people thinking clearly when the moment comes rather than reacting. Treat the rehearsal as preparation for a performance, not a compliance exercise.Balance challenge and support consciously: Look at how challenge and support are split across the chair, the board and the executive team. One person rarely carries both well, which is why strong chief executives tend to work in a pair. Decide which the organisation needs most in its current situation, and be explicit about who provides it.The Boardroom Path is the essential podcast for aspiring and newly appointed Non-Executive Directors (NEDs) navigating the journey from executive leadership to the boardroom.
