Ultra-large capital projects are the building blocks of the world's infrastructure, and with scale, complexity in delivery grows exponentially and risks are unparalleled, which has resulted in the average global project scorecard showing a 30-40% overrun in cost and time. This equates to a waste of some US $4 trillion annually. This book identifies the deadly project sins the world has made a habit of committing and addresses the question boards around the world responsible for these project failures find themselves asking time and time again, 'why, when we have identified the majority of these mistakes, errors and inefficiencies, addressed them in our systems and organisational design, do we keep making these same issues that result in failure?' The book reverse-engineers the sins to form 10 project delivery principles that are explained in detail and supported through the delivery of a virtual Ultra-Large Project that engages all readers in a solution that spans the complete project life cycle, covering all practices from the boardroom to the coalface. The book is more than a comprehensive solution to a global problem; it is a call to action for all involved in project delivery to address the root causes of project failure by adopting the appropriate mindsets and building robust practices and routines into project delivery.
