When choosing to upgrade to Windows Vista, IT managers must decide whether the additional features will create any real value.

Cesare Tizi, ZDNet Australia's CIO of the year, shared an insight into maximising value, "It's a challenge moving the business from, say, Windows 2000 to Windows XP and getting enough value to justify that, let alone moving it to another environment," he said. He also noted that Windows Vista requires a lot of computing power.

Tizi gave the example of a call centre, and said it would be hard to justify such an upgrade when most users need nothing more than e-mail and the basic applications. However, Tizi also said that an upgrade to Vista would eventually be inevitable, but "it might take longer than Microsoft thought it might take."
