Most board chair role descriptions read like a procedural document. Run the meetings. Set the agenda. Lead the CEO evaluation. Sign the things. Useful, but it is not the job.
The actual job, in my observation after fourteen years chairing a complex multi-entity organisation, has four parts. None of them appear on the formal role description.
Part one: hold the long view that the executive cannot
The CEO is, by structure, in this quarter. The chair has to be in five years. Every conversation the chair has with the CEO is, at some level, an exercise in pulling the time horizon out. What does this decision look like in three years? In ten? Who will inherit the consequences? Most CEOs welcome this if it is offered well. Most boards do it badly.
Part two: protect the CEO’s relationship with the truth
The longer a CEO is in role, the harder it gets for them to hear honest information. People around them learn what they want to hear, what to dampen, what to leave out. The chair is one of the very few people structurally positioned to tell the CEO things nobody else will. This is why the chair-CEO relationship has to be honest enough to bear it – and why a chair who only ever agrees with the CEO is failing at the central thing.
Part three: hold the board itself
A board is a group of senior people who, between them, know more than the CEO does. But they only contribute that knowledge if the chair builds the conditions for it. That means agenda discipline (papers in advance, decisions named clearly, no reading aloud), and conversation discipline (everyone speaks, the loudest do not run the room, the disagreements are named, not buried). Most boards drift toward consensus because the chair lets them.
Part four: govern the things that govern everything else
Risk management, succession, culture, capital. These are the things a chair is judged on at fifteen-year intervals, and they are the things that get the least time at any given board meeting. A chair has to deliberately drag the board back to them, every quarter, against the gravity of the operational issues that always feel more urgent.
One thing I would do differently
I would have invested in peer relationships with other board chairs much earlier. The job is lonelier than it looks, and the conversations you most need are the ones with people doing the same role somewhere else. There is no substitute. If you are a board chair without those, build them this quarter.
