Manager without portfolio
Manager without portfolio is a manager in title only, that is, one who manages a function, but does not manage a staff.
The term often applies to those holding managerial titles in small companies. E.g., the marketing manager or human resources manager in a small enterprise may be wholly responsible for the marketing or human resources functions respectively, but may not in fact manage any staff. It may also be applied to one granted a title for purposes of prestige, or for a or "short-timer".
Derived by analogy from the British term Minister without Portfolio.
