After a review of 16,000 megaprojects including skyscrapers, airports, museums, concert halls, nuclear reactors, roads, and hydroelectric dams across 136 nations, data show 47.9% are delivered on budget, 8.5% are delivered on budget and on time, and 0.5% are delivered on budget, on time, and with the projected benefits. 99.5% fall short because of poor planning, optimism, hubris, politics and more. The key recommendation is to spend more time planning.
