A founder says they need an Executive Assistant.
Another says they need a Chief of Staff.
A third says they need “someone senior who can just make things happen.”
They may be describing three different roles.
Or they may be describing the same underlying problem:
too much is flowing through the executive, and the business needs a better way to manage it.
The title matters less than understanding where the friction actually sits.
Executive Assistant: protecting the executive's operating environment
At senior level, an Executive Assistant does considerably more than manage a diary.
The role can sit across complex calendar management, international travel, meeting preparation, stakeholder coordination, communications, expenses, events, follow-up and the constant prioritisation surrounding an executive's working life.
The best Executive Assistants build significant context around the person they support.
They know what deserves access to the calendar.
They recognise competing priorities.
They anticipate requirements.
They understand relationships.
They reduce the number of operational decisions that need to reach the executive.
If the principal problem is that the executive's working environment has become difficult to manage, senior EA support may be exactly what is required.
Chief of Staff: helping leadership drive organisational priorities
A Chief of Staff typically addresses a different layer of complexity.
The role often operates across strategic priorities, leadership alignment, decision-making, cross-functional initiatives, executive communications and the translation of leadership intent into organisational action.
Exact responsibilities vary considerably between organisations.
In one company, a Chief of Staff may be heavily strategic.
In another, the role may combine operations, projects and executive-office responsibilities.
That variation is precisely why businesses should diagnose the work before choosing the title.
If the primary problem is strategic coordination across the organisation rather than the executive's own operating environment, a Chief of Staff may be the more appropriate structure.
Executive Operations: the space between the executive and execution
There is another category of work that does not always sit neatly inside either traditional definition.
Executive operations.
This is the practical infrastructure surrounding senior leadership.
It can include coordinating leadership activity, preparing meetings, maintaining actions, managing executive projects, organising complex travel, supporting board or investor activity, coordinating stakeholders, delivering leadership events and making sure priorities actually move.
It is less about owning corporate strategy and more about creating the operational conditions in which leadership can execute effectively.
For some businesses, this is the missing layer.
They do not necessarily need another strategist.
They need someone experienced enough to take ownership of complexity.
Start with the problem, not the job title
Before opening a vacancy, look at where the pressure actually exists.
If the executive is drowning in calendar, travel, communication and coordination, that points toward senior Executive Assistant support.
If leadership priorities repeatedly stall between departments or require strategic coordination, that may point toward a Chief of Staff.
If the problem sits across executive support, projects, meetings, stakeholders and operational delivery, executive operations may be the better description.
And sometimes the requirement crosses boundaries.
Titles are useful.
Work rarely organises itself quite so neatly.
Seniority matters more than terminology
Two people can carry the title Executive Assistant and operate at completely different levels.
The same is true of Chiefs of Staff.
A title alone tells you very little about judgement, autonomy, commercial awareness or the complexity someone can handle.
When defining support around a senior executive, consider:
What decisions should this person make independently?
How much organisational context will they need?
Which stakeholders will they represent the executive with?
What level of ambiguity must they handle?
Will they simply execute instructions, or will they be expected to anticipate what happens next?
Those questions reveal more about the required level than the job title does.
You may not need another permanent role at all
There is also a fourth possibility.
The business may have a genuine executive-capacity problem without yet needing another permanent position.
Perhaps the workload fluctuates.
Perhaps the requirement is project-based.
Perhaps a founder needs two days of senior support each week.
Perhaps a leadership team needs additional capacity during an intense period of growth, travel, investment activity or organisational change.
In those circumstances, fractional or interim support can provide the capability without forcing the business to define a permanent role prematurely.
Diagnose before you hire
The question therefore should not begin:
“Do we need an EA or a Chief of Staff?”
Start one step earlier.
What is currently consuming leadership capacity?
Where is execution breaking down?
What work repeatedly returns to the executive?
Which responsibilities genuinely require another permanent employee?
Answer those questions first.
The right structure usually becomes much clearer.
Because the goal is not to choose the most impressive title.
It is to create the support structure that allows leadership and the business around it to operate better.
