The extent of the research effort:
• Since March 2009
• 5,000 to 7,000 professional hours
• Approx. 20 people in the Research Team
This equates to about 3 person years of senior staff time. It is more effort than a typical PhD that involves 3 years study and it was carried out by highly experienced practitioners and established leaders in the industry.
Study benchmark against other research
• A detailed questionnaire to all relevant projects was undertaken (the sample size of 71 is high with a 64% response rate is high)
• 14 in depth case study projects compares well with the 8 used in the Fitzgerald review of PPPs and other case study projects that typically have less than 10 projects
