(i) Post-implementation reviews are particularly important for projects where perceived value for money has declined since contract letting. Departments need to identify whether such a decline reflects errors of judgement by the authority when letting the contract, the contractor failing to deliver the service as promised, short term problems during the early period of the service delivery, or other factors such as high charges for additional services.
(ii) There is very little information available on the returns which private sector contractors earn on PFI projects. It is impossible to tell whether these are reasonable in relation to the quality of the service delivery and the risks which the contractors bear. The OGC should complete its current review of contractors' returns as a matter of priority.
