provocative maintenance
[Common ironic mutation of "preventive maintenance"] Actions performed upon a machine at regularly scheduled intervals to ensure that the system remains in a usable state. So called because it is all too often performed by a field servoid who doesn't know what he is doing; such "maintenance" often *induces* problems, or otherwise results in the machine's remaining in an *un*usable state for an indeterminate amount of time. See also scratch monkey.
