 Bent Flyvbjerg, a professor at the Saïd Business School of the University of Oxford says that globally, megaprojects make up 8 percent of total global GDP.Care in the project development process is required to reduce any possible optimism bias and strategic misrepresentation, as a curious paradox exists in which more and more megaprojects are being proposed despite their consistently poor performance against initial forecasts of budget, schedule, and benefits.Megaprojects are often affected by corruption leading to higher cost and lower benefit.
