Over the past twenty years, Information Technology (IT) has become more and more central to business.

IT organisations operate in a complex, vulnerable, and rapidly changing environment. Their mandate spans from managing business critical processes, a multitude of technologies, to operating in a virtual ‘Cloud’ environment. This complexity, together with cost reduction imperatives, has driven many organisations to outsource part of their services, where data, processing, or even the services themselves are managed by a third party.
