To fully investigate the VfM concepts, in depth analysis through case studies was undertaken. This included data gathering and analysis through interviews, document review and desktop research. An advantage of the case study method of research is its unique ability to incorporate a full range of evidence types, including documents, archival records, interviews and observations106. This enables the consideration of a broad range of historical, attitudinal and observational issues and also allows for the inclusion of context.
The key objectives of the case study analysis were to:
• Explore and understand key factors and contextual influences on the individual alliances.
• Explore, understand and identify areas of potential enhancement or erosion of VfM throughout the lifecycle of the project.
• Explore and understand the alliance's concept of VfM vis-a-vis that in the business case.
• Establish an understanding of a broad range of aspects of the particular alliance.
• Make an assessment of the alliance's performance in a broad range of areas.
