15 In six of the eight case studies we examined the Department has procured and managed successful PFI solutions. One project was cancelled before contract letting and one other contract we examined will need to be renegotiated. In the PFI projects we examined the Department has therefore generally achieved effective allocation and management of risk. The allocation and management of risk, which has been the focus of this examination, is however not the sole contributor to value for money. Effective competitions, or strong benchmarking processes where there is a single supply source, are also needed to obtain the best prices for the risks transferred. The case study contracts we examined were all procured through competitive tendering.
