3.1 The aim of Stage 1 is to provide a clear strategic direction, whilst indicating where there may be a need, later in the process, for flexibility in the chosen procurement route for some projects. Programmes must take account of the fact that a percentage of projects are likely to switch procurement routes at Stage 2, and a very small minority of projects at Stage 3 where there is, for example, market failure. The department must ensure that as far as possible switching away from PFI is a real option where their priorities are such that they need to continue with the project.
