re: Why IT Outsourcing Often Fails
You concisely summed up the entire article in one sentence, "depends on what you ... outsource and how you manage the vendor". In fact, most of your examples seemed to point toward failures of oversight or vague SLA development. Human nature is to get away with the minimum investment for maximum return and most will try everything with that objective in mind. The responsibility however rests with the staff in the company doing the outsourcing in the development and enforcement of specific, goal oriented SLAs and process selection.
