The Chair-CEO Relationship: The Governance Variable Boards Can No Longer Afford to Ignore

## The Relationship at the Centre of Governance

Corporate governance frameworks devote considerable attention to board composition, committee structure, and director independence. Far less attention is paid to the single relational dynamic that shapes how all those structural elements actually function: the working relationship between the board chair and the chief executive officer. When this relationship works well, it creates the conditions for rigorous oversight, constructive challenge, and strategic alignment. When it deteriorates — through ambiguity, mistrust, or poor role definition — structural safeguards are insufficient to prevent serious governance failures.

The OECD Principles of Corporate Governance (2023 edition) identify the chair's role as foundational to board effectiveness, noting that the chair is responsible for leading the board, facilitating productive board-management relations, and ensuring that directors receive accurate and timely information. What the Principles do not specify, because no framework can, is how the chair and CEO must actively cultivate and maintain the relational conditions that make those obligations achievable.

## Role Clarity Is a Necessary but Insufficient Condition

The most common governance intervention when the chair-CEO dynamic is troubled is role clarification — articulating where the chair's authority ends and the CEO's begins. This is necessary. Ambiguity about who sets the board agenda, who speaks for the organisation externally, and who manages executive performance creates friction and reputational risk. Research published through the Harvard Law School Forum on Corporate Governance has documented how role boundary confusion contributes directly to board dysfunction and, in several high-profile cases, to delayed responses to organisational crisis.

However, role clarity alone does not produce a functional relationship. Two individuals can have perfectly delineated responsibilities and still fail to communicate effectively, withhold critical information from each other, or allow interpersonal tension to infect board dynamics. Role clarity defines the architecture; the relationship provides the load-bearing structure.

## What Research Reveals About Relational Quality

The Australian Institute of Company Directors (AICD) has consistently emphasised in its board effectiveness research that chairs who invest deliberately in their relationship with the CEO — through regular one-on-one meetings, structured feedback conversations, and proactive management of tension — produce measurably better governance outcomes. Boards chaired by individuals with strong relational skills report higher levels of director engagement, more candid information flows, and greater CEO accountability.

INSEAD's work on leadership dyads reinforces this finding from a psychological perspective. Their research on senior executive pairs identifies three conditions that determine whether the relationship between two leaders creates or destroys organisational value: trust calibration, constructive tension tolerance, and aligned purpose. When the chair and CEO share a clear understanding of the organisation's strategic purpose, can sustain productive disagreement without it becoming personal, and have calibrated their mutual trust through experience rather than assumption, the dyad functions as a governance asset. When any one of these conditions is absent, the dyad becomes a liability.

Personality and behavioural data add a further dimension. Assessments using instruments validated for senior leadership contexts — such as those developed by Hogan Assessments — reveal that derailment risks at the chair and CEO level frequently manifest not in individual profiles but in the interaction between them. A chair with high scepticism paired with a CEO with high boldness, for instance, can produce either exceptional strategic scrutiny or paralysing conflict, depending on whether both individuals have the self-awareness and relational skill to manage the dynamic deliberately.

## The Succession Transition as a Critical Governance Moment

No moment tests the chair-CEO relationship more severely than leadership transition. When a new CEO is appointed — whether through planned succession or unexpected departure — the chair becomes the primary governance anchor. The chair's ability to onboard the incoming CEO, calibrate expectations, and establish the relational norms that will govern their working partnership is among the most consequential governance acts a board will perform in any given decade.

Boards that treat CEO succession as a selection process alone, rather than as the beginning of a relational architecture that must be actively constructed, routinely underestimate the cost of misalignment in the early tenure period. Academic analysis of CEO performance data, including work reviewed through the Harvard Law School Forum on Corporate Governance, consistently shows that first-year CEO performance is substantially mediated by the quality of board support — with the chair relationship functioning as the primary mechanism through which that support is delivered or withheld.

## Practical Implications for Board Assessment

Given this evidence, effective board assessment must treat the chair-CEO relationship as a discrete governance variable, not merely as a byproduct of broader board evaluation. The following practices reflect current best thinking:

- Annual one-on-one review sessions between the chair and CEO, structured around both performance accountability and relational health, should be documented as a governance practice rather than an informal courtesy. - Board assessments should include a specific module evaluating the effectiveness of the chair-CEO dynamic, drawing on confidential input from both individuals and, where appropriate, from other directors and senior executives who observe the relationship in practice. - Chairs should undergo periodic development that builds relational and coaching competencies, not merely technical governance knowledge. The chair role is, in significant part, a leadership coaching role — and most chairs are appointed for their professional expertise, not their relational skill. - Where the relationship has deteriorated, boards should engage qualified external governance advisers early. The cost of an unresolved chair-CEO rift — in director time, executive distraction, and strategic drift — consistently exceeds the cost of structured intervention.

## Governance Quality as a Relational Achievement

Governance quality is ultimately not an organisational property; it is an interpersonal achievement, renewed continuously through the quality of the conversations, decisions, and trust-building acts that occur between people. The chair and CEO relationship sits at the centre of that achievement. Boards that treat this relationship as something that either works or does not — rather than as something that must be deliberately developed, periodically assessed, and actively protected — are accepting a governance risk that no committee structure or policy framework can adequately mitigate.

The most effective boards understand that structural independence is a precondition for good governance, not a guarantee of it. What converts structure into function is the quality of the human relationship at the apex of the governance system.
