Why does it happen?
Can someone explain to me why almost every procurement programme goes bottom up? It seems that since 1945 no one has been able to bring a project of any kind in on time and on budget. Why haven't we learned lessons from previous projects? Is it that everyone in procurement/industry/civil service/armed forces are just incompetent or is it that systems are so complex no one has a cat in hell's chance of meeting budget/time line constraints? Do tell
