This article provides an answer to what has been called the biggest problem in theorizing and understanding planning: the ambivalence about power found among planning researchers, theorists, and students. The author narrates how he came to work with issues of power and gives an example of how...

Dan Lovallo and Daniel Kahneman must be commended for their clear identification of causes and cures to the planning fallacy in, “Delusions of Success: How Optimism Undermines Executives’ Decisions” (July 2003). Their look at overoptimism, anchoring, competitor neglect, and the outside...

When I first became interested in in-depth case-study research, I was trying to understand how power and rationality shape each other and form the urban environments in which we live (Flyvbjerg, 1998). It was clear to me that in order to understand a complex issue like this, in-depth case-study...

This article examines five common misunderstandings about case-study research: (1) Theoretical knowledge is more valuable than practical knowledge; (2) One cannot generalize from a single case, therefore the single case study cannot contribute to scientific development; (3) The case study is most...

In what follows I will: (1) Argue that a major problem in megaproject policy and planning is the high level of misinformation about costs and benefits that decision makers face in deciding whether to build, and the high risks such misinformation generates; (2) Explore the causes of...

Some years ago, I was threatened by a high-ranking government official as I was beginning research on cost overrun in large public works projects. The official told me in no uncertain terms that if I came up with results that reflected badly on his government and its projects he would personally...

Project promoters, forecasters, and managers sometimes object to two things in measuring inaccuracy in travel demand forecasting: (1) using the forecast made at the time of making the decision to build as the basis for measuring inaccuracy and (2) using traffic during the first year of...

A major source of risk in project management is inaccurate forecasts of project costs, demand, and other impacts. The paper presents a promising new approach to mitigating such risk based on theories of decision-making under uncertainty, which won the 2002 Nobel Prize in economics. First, the...
