Who should be involved in assessing the impact of the change? 

There is likely to be may be a range of individuals within the government party or other  stakeholders who should be consulted to fully assess the impact of a proposed change. In addition, it may be appropriate to work jointly with the private party to assess the potential impact of the change.

In assessing any change request, careful consideration should be given to the impact of the change. For example, some performance measures may become irrelevant if one performance requirement is changed. In these circumstances, the government party should consider whether an amendment to the project deed to introduce a new performance measure would be appropriate. The contract administration manual should also be updated to take account of each change. Furthermore, variations in performance requirements which increase costs can lead to price variations and compromise the original value for money outcomes.
