A determination is made when a proposed change associated with an object is made; an impact analysis is performed on the proposed change; the change is implemented when the impact analysis indicates that there is no impact on, other system stakeholders otherwise: a change object based on the proposed change is created, voting rights are allocated to users based on the impact analysis; and the proposed change is accepted or canceled in response to the voting. Change control contracts may be associated with the objects. The contracts may be customized to establish change management rules for and enterprise and to specialize rules for certain objects or branches of a Content Class tree corresponding to a department or a discipline. The access to changing the contracts may also be limited to help ensure that the contracts are not bypassed.
