A leadership gap is not always a crisis. But it is always a decision: should the role stand empty while the search process runs, should someone internal fill it temporarily, or should an interim leader come in from outside?

My experience is that interim is right in three situations. When the role carries operational responsibility for results that cannot wait – an empty chair costs more than a temporary leader. When the organisation is in a restructuring where it is an advantage that the person carrying it out is not staying. And when the board needs time to run a proper search process without putting operations on hold.

Interim is the wrong move when the gap is really a symptom – of an unresolved strategy, an ownership conflict or an organisation that does not hold together. A temporary leader does not solve that problem; it postpones it, with interest.

The most important advice is still simple: settle the mandate before day one. An interim leader without a clear mandate becomes an expensive stand-in. With a clear mandate, a defined period can move the company further than a normal year.
