Move the People But Not the Process?

What good can possibly come of an initiative to relocate over 200 people from over 100 different offices around the country into one central office with no intention to refine the processes they use? The intent is to reduce costs. The initiative is some misguided manager's idea of a consolidation. The relocation costs are astronomical. The assumption is there will be cost savings realized from the effort. How? How does any manager intend to save money simply by relocating 200 different people if the processes they used before the move are the same processes they will be using AFTER the move? Worse, what level of senior management approved such a move without a clear ROI?
