In assessing the overall value for money of different procurement options, consideration should be given to the possibility that different procurement routes may lead to wider (non-financial) benefits and costs. If there is good evidence to suggest that different procurement routes would lead to differential benefits (or costs), then this should be taken into account in the VfM assessment.
Factors that should be considered are those that have a differential impact on NPD versus conventional procurement. These may include (although not in every case) factors such as the quality of the design, environmental considerations or innovations that can be adopted for wider use by the Authority (where there are not intellectual property right issues). These factors can have a significant impact on the quality of service delivery and should not be down played.
