Mission creep and micromanagement are disorders of a board. The symptoms and cures are different. Both create disruption in an organization. Mission creep is not a disparaging characterization of a member of the board.

It is the process where a gradual shift in purpose occurs, with or without awareness. In organizations with limited resources, the expansion of the mission will dilute programs and services. A board that tries to be all things to all people will exhaust resources and reduce the quality of programs and services.
