After seeing a slight dip in 2016, global IT spending is expected to increase by 2.7 percent this year, according to recent research from Gartner. The "Gartner Worldwide IT Spending Forecast" projects moderate to impressive growth in all leading sectors. Enterprise software will account for the biggest increases, at 6.8 percent, followed by IT services (4.2 percent) and data center systems (2.6 percent). Still, any expansion in technology spending will greatly depend on ever-shifting global political and economic conditions. "The range of spending growth from the high to low is much larger in 2017 than in past years," said John-David Lovelock, research vice president at Gartner. "Normally, the economic environment causes some level of division. However, in 2017, this is compounded by the increased levels of uncertainty. The result of that uncertainty is a division between individuals and corporations that will spend more—due to opportunities arising—and those that will retract or pause IT spending." The research includes a 2018 forecast with similar growth projections, and we've included those here. Gartner bases its forecast on an analysis of sales on the part of thousands of vendors in multiple IT sectors.
