According to Gartner, the manufacturing and natural resources sector will lead the vertical markets with total spending expected to reach $478 billion in 2013, up 2.3 percent from $467 billion in 2012.

The analyst firm says that manufacturers typically plan and manage a significant portion of their IT costs in expectation of changes in their sales. Additionally, manufacturers worldwide have been steadily reducing their IT purchases as a percentage of their sales since the recession of 2008. The manufacturing industry’s IT buying center has adopted tighter IT cost controls amid a myriad of mixed market signals. However, IT spending rates are expected will bottom out in 2013 and will be resilient over the long run, as business confidence is restored and the value proposition of a nexus of new technology forces ? social, mobile, big data and cloud ? is increasingly championed by senior leaders.

Gartner adds that the banking and securities sector will have strong growth in 2013 and is expected to reach $460 billion in 2013, up 3.5 percent from $445 billion in 2012. Banking and securities is an IT-intensive industry, spending approximately three times as much on IT as a percentage of revenue than the average of all industries. This trend is expected to continue due to a significant amount of IT required to run activities such as lending, payments, trading and risk management.

The CMS sector is forecast to grow 3 per cent in 2013 to $426 billion, up from $414 billion in 2012. Firms in the CMS sectors will typically spend approximately 5 per cent of their revenue on IT on average over a five-year period, well above the median for all industries.

In the short term, transportation and insurance will also be high-growth sectors with both reaching more than 4 percent growth in 2013. IT spending in the transportation sector is expected to total $126 billion in 2013, up from $121 billion in 2012. IT spending in insurance will reach $187 billion in 2013, up from $179 billion in 2012.

In 2012, government IT spending is forecast to decline 2 per cent and the decline is expected to continue through 2013. In 2013, government IT spending is forecast to total $445 billion, down from $447 billion in 2012.

Large industry market operating under fiscal pressure, such as government, can also provide market opportunities as IT departments must strive to modernise and increase service levels without increasing resources. The need for greater efficiency and productivity gains in industries operating under severe fiscal constraints can also create opportunities for disruptive IT innovation and for the displacement of incumbent IT market leaders.
