To ensure good quality assurance, Cabinet has approved the use of a "Gateway Review Process" for quality assurance of large or high-risk state sector projects. In essence, the process requires six separate reviews by independent experts. However, the results of the reviews are not publicly available - they are provided confidentially to the project's senior responsible official.
Guidance for this process and whether a project needs to be subjected to it is provided by the State Services Commission and is not detailed in this document.4
The numbers in the first column in Figure 1 represent the timing of the first four Gateway reviews in relation to the key stages in the PPP project life cycle.
