The Chief of Staff has become one of the most valuable and least understood roles in a leadership team. Here is what it actually does, and when a business needs one.
What the role really is
A Chief of Staff exists to extend a leader's capacity and effectiveness — usually a CEO's. They drive the leader's priorities across the organisation, make sure important decisions are actually made and followed through, run the rhythm of the leadership team, and take on the cross-cutting initiatives that fall between functional owners. It is a role about leverage: helping one leader have more impact across a complex business.
What it is not
A Chief of Staff is not a senior personal assistant, and not a shadow decision-maker. The best operate through influence and trust rather than formal authority — connecting people, unblocking work, and driving execution without owning a function outright. Misunderstanding the role, in either direction, is the most common reason it fails.
When a business needs one
The role earns its place when a CEO's span of attention becomes the bottleneck — when too many important things need driving across the organisation for one leader to hold alone. In fast-growing or complex businesses, a strong Chief of Staff can be the difference between a CEO who is stretched thin and one who is genuinely effective across the whole.
What it means for hiring
Because the role runs on trust and fit with a specific leader, hiring a Chief of Staff is as much about chemistry and judgement as about experience. Defining what this Chief of Staff will own, and finding someone the leader genuinely trusts, is central.

What does a Chief of Staff do?
They extend a CEO's capacity — driving priorities across the organisation, ensuring decisions get made and executed, running the leadership rhythm, and handling cross-cutting work between functions. It's a role about leverage and execution.
Is a Chief of Staff the same as an executive assistant?
No. An executive assistant manages a leader's schedule and administration; a Chief of Staff drives strategic priorities and execution across the organisation through influence and trust. They are very different roles.
