In summary, adhocracies are characterized by flexible, adaptive structures in which multidisciplinary teams of professionals are formed around specific problems or objectives. They tend to have constantly changing units (as opposed to the relatively stable functional departments of bureaucracies). New units are formed to deal with new problems or objectives. Old units either are dissolved as problems are solved, or change their makeup as different stages of the project are reached.

Adhocracy means that the different parts of an organization are temporarily assembled to meet the requirements and needs which apply at any particular point in time. […] [Henry] Mintzberg considers that adhocracy is characterized by an organic structure, a low degree of formalization, a high degree of horizontal work specialization based on formal training and specialist competence, a tendency to group specialized personnel in functional units to facilitate administration and personal development ("housekeeping purposes"), while employing them in small, market-based project groups in work organizations. Coordination and management are characterized by decentralized decision making to a relatively high degree, and by mutual adaptation at the project group level, rather than by control from above.
