Evaluating success levels of mega-projects

Today's mega-projects transcend the traditional trajectories traced within national and technological limitations. Powers unleashed by internationalization of initiatives, in for example space exploration and environmental protection, are arguably only temporarily suppressed by narrower national, economic, and professional disagreements as to how best they should be harnessed. While the world gets its act together there is time to develop the technologies of such supra-mega-project management that will synergize truly diverse resources and smoothly mesh their interfaces. Such mega-projects and their management need to be realistically evaluated, when implementing such improvements. This paper examines current approaches to evaluating mega-projects and questions the validity of extrapolations to the supra-mega-projects of the future. Alternatives to improve such evaluations are proposed and described.
