The research might differ - and differ significantly - but one thing is for sure: IT is on pace for record spending in 2013. This month, researchers at Forrester and Gartner offered up their projections for IT spending, including different views of how these expenditures will break down.
Researchers at Gartner project a total global IT spend of $3.7 trillion in 2013. That amount is a moderate (2%) increase over 2012, but a larger increase (4.1%) is projected for 2014. They see the largest area of growth coming in IT enterprise software and the largest total expense in telecom services. From their report, it appears that the spike in spending on devices - fueled by a significant investment in tablets and other mobile devices - in 2012 (10.9%) has leveled off in 2013 (2.8%).
Forrester Research's annual report on global IT spending (nicely summarized by Ingrid Lunden at TechCrunch) offers a different take. They see a smaller overall spend of $2.1 trillion with a greater overall investment in IT software ($542 billion). The Forrester report also provides insight into the types of software that this investment comprises. IT spending on applications is showing significant gains, which goes hand-in-hand with the increased utilization of tablets, particularly iPads.
