Claim 0:
1. A controller configured to manage and execute a plurality of functions in units of predetermined function group, the controller comprising:
a partition updater configured to change a function grouper; and
a mode changer configured to receive a function group change implementation request for instructing change of a function group in response to a change in an operation environment of a system from an outside of the controller, and, in response to the function group change implementation request, permits execution of the function group changed by the partition updater; and wherein
before receiving the function group change implementation request, the mode changer receives a function group change preparation request for requesting preparation for change of the function group from an outside of the controller, acquires change information describing matters to be changed from an outside of the controller in response to the function group change preparation request, and instructs the partition updater to change partition of the function group, and
the partition updater resets partitioning of the functional group on a basis of the change information.
