Why do CIOs choose to outsource? Is it to drive down costs or to tap into skills they don't have in-house?

Speakers and delegates at the 2010 CIO Summit say they are using outsourcers as a way of expanding capability rapidly without employing an army of permanent staff.

For others, it's about buying in expertise so that the company can punch above its weight in the market.
