A potential but often overlooked contributor to the governance failures emerging across various public boards is the growing trend of directors and board chairs holding multiple board appointments at the same time. 

While experience and expertise are valuable assets, overextension can quietly erode the very oversight these positions are meant to provide.

Board service is not ceremonial. It is a serious fiduciary duty. Directors are entrusted with safeguarding public resources, ensuring compliance with laws and policies, managing risk, and holding executive management accountable. These responsibilities demand time, preparation, and sustained engagement. 

When individuals sit on numerous boards simultaneously, the question must be asked: how effectively can they discharge these duties?

The reality is that board work extends far beyond attending meetings. It involves reviewing lengthy documents, understanding financial statements, scrutinising procurement decisions, evaluating audit findings, and asking difficult questions. It requires familiarity with sector-specific regulations and the unique operational challenges of each entity. When directors are stretched thin, oversight can become superficial, and critical warning signs may be missed.

This is not necessarily about bad intentions. It is about capacity. Even the most competent and well-meaning director cannot give full attention to several complex organisations at once. The result can be delayed decisions, inadequate scrutiny, and a tendency to rely too heavily on management representations without rigorous challenge. Over time, this weakens the board’s role as a check and balance and increases the risk of mismanagement going undetected.

Board chairs face an even heavier burden. They set agendas, guide discussions, manage conflicts, and often act as the key link between the board and executive leadership. When chairs juggle multiple chairmanships or numerous directorships, their ability to provide strategic leadership and close supervision inevitably suffers. Leadership spread too thin becomes leadership in name only.

There is also a broader governance issue. Concentrating board positions among a small pool of individuals limits diversity of thought and reduces opportunities for emerging leaders to contribute. Fresh perspectives are essential for innovation, strong risk management, and independent thinking. Recycling the same directors across multiple boards can create networks of familiarity that weaken objectivity and reduce the likelihood of robust challenge.

Good governance requires more than qualifications on paper. It requires time, presence, and independence. Policymakers and appointing authorities should consider clear limits on the number of boards one individual can serve on, especially in public bodies. 

Performance evaluations of boards should also assess director engagement, not just attendance, but preparedness and contribution.

Ultimately, oversight failures rarely stem from a single dramatic act. More often, they arise from gradual inattention, missed signals, and unanswered questions. When those responsible for asking the hard questions are overcommitted, the system becomes vulnerable. Strong institutions depend on directors who are not just appointed, but truly available.
