What does a non-executive director actually do, and what is a board for?
A board is the body that directs the company — as distinct from managing it — and a non-executive director is a member who is not an employee, brought in for independent judgement, experience and oversight.
What a board is actually for:
Setting strategy and approving major decisions.
Holding management accountable for delivering against it.
Overseeing risk, controls and compliance.
Appointing, assessing and if necessary removing the chief executive — arguably its single most important function.
Ensuring the company's obligations are met, since directors carry personal legal duties.
The distinction that matters: the board directs; management runs. A board that starts operating the business has lost the ability to hold anyone to account for operating it, which is the most common dysfunction in small company boards.
What a non-executive brings:
Independence. No job to protect, no internal politics, and the ability to ask the question everyone is avoiding.
Experience of things you have not done yet — a first acquisition, a first fundraise, a downturn.
Challenge to the chief executive, which nobody employed by the chief executive can do freely.
Networks and credibility with investors, lenders and customers.
Oversight of what executives cannot assess objectively — their own performance and pay.
What non-executives are not: consultants, part-time executives, or a source of free labour. Using them to do work is a common and value-destroying mistake.
The legal point that surprises people. In UK law there is no distinction between executive and non-executive directors' duties. A non-executive owes the same statutory duties, carries the same potential liabilities, and cannot defend themselves by saying they were only part-time. This is why proper information, minutes and insurance matter.
When a small company should get one: at the point where the founder has no one to be genuinely challenged by, before a fundraise or sale, when entering unfamiliar territory, or when investors require it.
What makes it work: a clear remit and time commitment, real information in advance, and a chair who runs proper meetings.
