The economic climate could be hastening the rise in non-tech managers procuring their own IT, undermining the power of the CIO, according to a KPMG researcher.\nResearch from the management consultancy suggests that global IT spend is expected reach $2.7tr by the end of 2012, a rise of 3.9 per cent.\nGrowth in spending on computer hardware, enterprise software, IT services and telecoms equipment was in line with the general trend, but far below growth recorded in the previous twelve months, at 6.9 per cent. This suggests corporates are putting the brakes on spend in infrastructure, the CIO heartland.\nMac Scott, associate director at KPMG\u2019s advisory team believes this could be one of the causes for business departments going their own ways in IT procurement.\nHe told CIO UK: \u201cTraditional IT projects in large organisations are viewed as very costly. Infrastructure investments are thought of as prohibitively high. The IT requirements for supporting growth in new markets is more flexible, with a low cost of implementation. Departments, like marketing and sales, which can\u2019t afford to make procurement decisions at the pace needed for large infrastructure investments are voting with their credit cards.\u201d\nScott pointed to the rise of the Chief Digital Officer in some US organisations, a role that does not site within the IT department, as a sign that IT spending is moving away from the control of the CIO.\nHe observed that marketing and sales departments are not traditionally seen as cost centres by the board, but as the engines for business growth. As a consequence they have access to lines of capital that other departments don\u2019t get. Increasingly, says Scott, this capital is being spent on guerrilla IT projects.\nScott said: \u201cJust like in crime thrillers, sales and marketing have method, motive and opportunity.\u201d\nScott told CIO UK that the trend for non-tech departments investing in their own IT is growing ,but still small scale at the moment and impacting only small fractions of the overall IT budget.
