World expert Bent Flyvbjerg and bestselling author Dan Gardner reveal the secrets to successfully planning and delivering ambitious projects on any scale.

Nothing is more inspiring than a big vision that becomes a triumphant, new reality. Think of how Apple’s iPod went from a project with a single employee to an enormously successful product launch in eleven months. But they are the exception. Consider how London’s Crossrail project delivered five years late and billions overbudget. More modest endeavours, whether launching a small business, organizing a conference, or just finishing a work project on time, also commonly fail. Why?

Understanding what distinguishes the triumphs from the failures has been the life’s work of Oxford professor Bent Flyvbjerg. In How Big Things Get Done, he identifies the errors that lead projects to fail, and the research-based principles that will make yours succeed:

- Understand your odds. If you don't know them, you won't win.
- Plan slow, act fast. Getting to the action quick feels right. But it's wrong.
- Think right to left. Start with your goal, then identify the steps to get there.
- Find your Lego. Big is best built from small.
- Master the unknown unknowns. Most think they can't, so they fail. Flyvbjerg shows how you can.

Full of vivid examples ranging from the building of the Sydney Opera House to the making of the latest Pixar blockbusters, How Big Things Get Done reveals how to get any ambitious project done ― on time and on budget.
