No. 2: Control of IT can be centralised or distributed
Binary Thinking: CIOs need to make a fundamental decision for their organisation. Either they will control all IT staff, assets and projects across the enterprise centrally or they will delegate everything out to local managers on a geographic and/or business-line basis. Unless a CIO chooses the centralised option they should probably resign.
Portfolio Insight: Different classes of IT service experience different economies (or dis-economies) of scale. Total centralisation or total distribution are just extreme ends of a whole spectrum of options. The optimum option for any enterprise is likely to be somewhere in the middle of the scale and not either end.
