Technology spending outside of IT will become almost 90% by the end of the decade, from 20% twelve years ago, according to Gartner.

Gartner said that most of the change is being driven by the digitisation of companies’ revenue and their services, and the Nexus of Forces is said to be leading this transformation.

According to Gartner, the Nexus is the convergence and mutual reinforcement of social, mobile, cloud and information patterns that drive new business scenarios.

Organisations are digitising segments of business that include moving marketing spend from analogue to digital, or digitising the research and development budget.

Organisations are also digitising how they service their clients, in order to drive higher client retention, and thirdly, they are turning digitisation into new revenue streams.

To address the changes, organisations will create the role of a chief digital officer as part of the business unit leadership, which will become a new seat at the executive table.

Gartner predicts that by 2015, 25% of organisations will have a chief digital officer.

Gartner vice president and analyst David Willis said that the chief digital officer will prove to be the strategic role in the coming decade, and IT leaders have the opportunity to be the leaders who will define it.

"The Chief Digital Officer plays in the place where the enterprise meets the customer, where the revenue is generated and the mission accomplished," Willis said.

"They’re in charge of the digital business strategy. That’s a long way from running back office IT, and it’s full of opportunity."

According to Gartner, IT leaders need to make sure they have policies and procedures in place to respond to the new Nexus-driven threats, and they must counter cyberattacks, and anticipate new attacks from new sources at a high scale.

Earlier this month, Gartner revealed that the rise in businesses dealing with more information will see Big Bata contribute $28bn to global IT spending in 2012.
