One area fraught with difficulty for contract management occurs as a result of government-initiated changes. It is important to use the same approach to changes as per the initial specification-specify outputs and parameters, not design details and inputs-to avoid unintentional assumption of risk by government. It is also important to bear in mind that the financiers will have funded the project on the basis of an agreed risk profile. If changes to the service requirements will involve material changes to the risk profile, the financiers will expect to be consulted-and may even seek a right of veto.
