But because the optimal cost of doing business will face cultural and political obstacles, many enterprises information long (CIO) are reluctant to raise such a possibility."

The past must pay for things as an asset, now can also be provided in the form of services. Most of these are like twins digital service product changed the spending patterns, from a one-off large amount paid into a low monthly fee. This means that although IT is the same activities, annual spending will have a big difference."
