The parts I hate are those planned centrally; which thankfully right now are mainly limited to IT, budgeting / expenses, etc. You can completely tell that at the CTO level it looks like we're saving gobs of money by planning centrally; but at the local level you can see that in fact what's happening is the costs are being externalized into other areas in ways that are difficult to measure, but probably end up costing the company at least 3x.
