More than one in five CIOs believe that their direct control over technology has diminished since the start of the recession, whilst the proportion of companies where more than ten per cent of technology spend lies outside the control of the IT department has almost doubled to 40 per cent in the last three years. Despite this, CIOs see their roles as growing in importance, but recognise that their value is increasingly driven through collaboration and influence, rather than direct control. This is according to the 15th Annual CIO Technology Survey 2013, conducted by Harvey Nash in association with TelecityGroup, presenting the views of more than 2,000 CIOs and technology leaders across twenty countries.
