IT spend to pass US$3.4tr in 2008

Despite economic concerns, worldwide IT spending will exceed $3.4 trillion in 2008, an increase of 8% over 2007 spending, according to Gartner.

The analyst house said much of this growth is based on the decline in the US dollar. The estimated worldwide IT spending growth expressed in constant currency is forecast to be approximately 4.5%.

IT spending is dominated by services rather than products. Together, IT services and telecom services account for 70% of total IT market spending. Gartner analyst said the telecom sector has a major effect on overall IT market performance, accounting for almost $2 trillion in 2008.

"Legacy telecom services have a dampening effect on sector growth, and therefore on the overall IT market," said William Hahn, principal research analyst at Gartner. "The dominant size of the telecom services market guarantees that even with the forecast for relatively slow growth, it will still comprise over 44% of the IT market in five years' time."

Jim Tully, vice president, Gartner, said, "In subsequent years we will see reduced growth, but the fundamentals remain strong. Emerging regions, replacement of obsolete systems and some technology shifts are driving growth."

He added, "Organisations are switching from company-owned hardware and software assets to per-use service-based models. This will impact the industry in various ways.

"The projected shift to cloud computing, for example, will result in dramatic growth in IT products in some areas and in significant reductions in other areas. In general, assets will be used more efficiently, and we are assuming that the overall effect on market growth will be neutral. We also recognize that there is considerable upside potential for higher growth."

Analysts said the IT services sector benefits from the continued innovation in software technology. New software solutions often require labour-based services to implement them.

"Most companies updated their software systems during the period 1997 through to 2001, so we are in the middle of an upgrade cycle that should extend past the end of this decade," said Joanne Correia, managing vice president at Gartner.

She added, "However, the replacement of systems does not automatically equate to new software market growth. Software as a Service (SaaS)/cloud computing, service oriented architecture (SOA)/Web 2.0, and open source software are causing huge changes to the software market. Many of these factors are impacting market growth as enterprises replace assets with per-use services."

The outlook for IT services market growth has improved despite macroeconomic uncertainty. "Spending in IT services is being supported by two main factors," said Kathryn Hale, research vice president at Gartner. "Businesses are investing in improvements to internal processes aimed at reducing costs, while often maintaining some of the prior interest in innovation. The second factor is that globalization allows IT services providers to mitigate the risk of weakening demand by operating in more markets."

The main area of hardware growth activity is PCs, which represents 60% of total hardware spending. Growth in PCs is stronger than previously expected, with no signs of a slowdown. The US forecast has increased marginally while forecasts elsewhere, particularly Asia/Pacific and Western Europe, have increased significantly.

"The market growth outside of the US and the effects of the weak dollar are major factors in growth in US dollar terms. In addition to regional shifts, a strong shift to mobile PCs is occurring. The higher prices of these products result in increasing revenue per unit and a boost to the overall market," Tully said.
