This research project case examines challenges and obstacles encountered when studying the decision-making process for mega projects. The research sought to analyse the extent to which institutional arrangements and power relationships are integral to understanding the nature and complexity of decision-making with regard to mega-project investments. A large number of narratives resources, including written materials and interview transcripts, were collected to answer the research questions and test the hypotheses. Rigorous examination of the case studies has identified which theoretical concepts are consistent with the hypotheses and helpful in their interpretation. This article provides an overview of the challenges encountered during the study and the solutions to the methodological problems. In addition to the analyses and conclusions, several tips and pointers collected from interviewee and questionnaire responses are also included in hopes of inspiring students interested in similar approaches. This research project case is composed of four parts. First, a list of learning outcomes from this case is provided. Second, a succinct description of the research background and research outcomes is given. Third, the difficulties and solutions of research design, the fieldwork practice and the data analysis are illustrated. Finally, the findings and conclusions of this study process are summarised.
