The secrets to effectively planning and completing big projects of any size are revealed by world authority Bent Flyvbjerg and best-selling author Dan Gardner. Nothing is more motivating than a grand vision that materialises into a glorious new reality. Consider how the Apple iPod evolved from a one-person initiative to a hugely successful product introduction in just eleven months. But these kinds of triumphs are rare. Think about how the Crossrail project in London was completed five years late and billions over budget. Even more modest endeavours, like starting a small business, planning a conference, or even completing a task on time at work, frequently fail. Why? Oxford professor Bent Flyvbjerg has dedicated his life to figuring out what separates successes from failures.
