As introduced in Part 2, the purpose of the quantitative analysis of procurement options is to support the identification of the procurement model offering the best overall value to taxpayers. As value for money includes both qualitative and quantitative elements, the procurement option ultimately selected will be the alternative deemed to best meet the criteria established by the project team. These criteria are determined based on the desired outcomes of a project, and are used to assess a particular procurement option's ability to support the project, with quantitative value as one key element. Additional detail on qualitative analysis is provided in Section 10.6. The inclusion of qualitative criteria in the value for money assessment means it is possible that the procurement option with the lowest NPC may not necessarily be the preferred option.
