How Big Things Get Done

**The secrets to successfully planning and delivering projects on any scale—from home renovation to space exploration—by the world’s leading expert on megaprojects
“This book is important, timely, instructive, and entertaining. What more could you ask for?”—Daniel Kahneman, Nobel Prize–winning author of **Thinking, Fast and Slow**
“Over-budget and over-schedule is an inevitability. Incompetence and grift is outrageous. Bent Flyvbjerg, with this terrific data-driven book, has shown that there is another way.”—Frank Gehry**
Nothing is more inspiring than a big vision that becomes a triumphant, new reality. Think of how the Empire State Building went from a sketch to the jewel of New York’s skyline in twenty-one months, or how Apple’s iPod went from a project with a single employee to a product launch in eleven months.
These are wonderful stories. But most of the time big visions turn into nightmares. Remember Boston’s “Big Dig”? Almost every sizeable city in the world has such a fiasco in its backyard. In fact, no less than 92% of megaprojects come in over budget or over schedule, or both. The cost of California’s high-speed rail project soared from $33 billion to $100 billon—and won’t even go where promised. More modest endeavors, whether launching a small business, organizing a conference, or just finishing a work project on time, also commonly fail. Why?
