Chief of Staff


Definition: a Chief of Staff is a person who supports the CEO of a large corporation. More senior than an Executive Assistant, they can perform following approximate roles:
- Air traffic controller (for the leader and the executive team).
- Integrator (connecting work streams that would otherwise remain siloed).
- Communicator (linking the leadership team and the broader organization).
- Honest broker and truth teller (when the leader needs a wide-ranging view without turf considerations).
- Confidant (without an organizational agenda).
A CoS acts with an implicit mandate of the CEO. This requires humility, maturity and situational sensitivity.
