The board role is often misunderstood – and it is changing fast. Where directors once sat on as many as six boards simultaneously, three is now the realistic limit. Financial oversight, remuneration and succession have all become more rigorous and time-intensive. 

Annet Aris, Senior Affiliate Professor of Strategy at INSEAD and Academic Director of INSEAD’s Corporate Governance Centre, has served on boards across Europe for more than 20 years. In the first episode of our new INSEAD Explains Governance series, she breaks down what board members actually do, how the role varies across company types, how the workload has grown, and the qualities that separate effective directors from ineffective ones.

How boards work and what shapes them

At its core, says Aris, board membership comes down to three responsibilities: financial housekeeping – ensuring accounts, risk management and compliance are in order; strategic challenge – not designing strategy but scrutinising and approving management’s proposals; and acting as management’s employer – evaluating executives, planning succession, and assessing remuneration and performance targets.

While these tasks remain constant, the ownership structure of a company shapes how they play out in practice. Listed companies face the most regulatory scrutiny, answering to dispersed shareholders and dense governance codes, Aris explains. Family-owned businesses add another layer: Non-family directors must manage not just commercial decisions but the dynamics that come with family involvement, such as internal tensions, inexperienced members and strong views about the company’s direction.

Private equity boards operate differently again, with a tighter investment horizon and a more hands-on, operationally focused style. Across all three, governance failures can often be traced to unchecked egos, absent oversight or destructive conflicts between management and owners.

Another common thread is that the demands on board members have grown substantially, says Aris. Strategy is no longer something settled at an annual retreat. In a volatile world, it requires boards to stay continuously engaged with geopolitics, technology and fast-moving market forces. 

The paradox at the heart of good governance

Aris argues that the most effective board members are able to stand firm when a decision feels wrong, even when the rest of the room disagrees. They also listen deeply to fellow directors and management, beyond the rational arguments to what is actually going on in the room.

Boards also need specialist expertise, but not at the expense of the broad perspective required for major decisions. And while experience matters enormously, the pace of change means that the best directors combine it with genuine humility about what the current situation demands.
