The case studies were conducted through a mixture of face to face interviews with key alliance Owner and Non-Owner personnel, and a detailed review of associated project documentation.
Consistency was achieved throughout the interviews by maintaining, to the maximum extent practicable, the same interview leader and the use of a structured set of interview topics.
Some of the Research Team members (Evans & Peck) had participated in varying roles in some of the alliances studied (advisor to the Owner, the NOPs or the alliance). To increase the integrity of the Study, internal processes were implemented within Evans & Peck that involved several peer reviews of all findings.
Each stage of the project lifecycle was analysed to determine actual performance and compared where possible to the business case and the TOC.
To properly investigate the case studies, it was important that the presentation of findings maintain confidentiality throughout the Study. In some instances this has meant some detail was removed from the data presented in this Study.
