Access to major new paper by Prof Bent Flyvbjerg added to PMWL

Bent Flyvbjerg is the first BT Professor and inaugural Chair of the Major Programme Management at the University of Oxford in the UK and the Villum Kann Rasmussen Profesor and Chair at the IT University of Copenhagen. He is the most cited scholar in the world of project management.
