UK organisations are investing heavily in wireless technology, but almost one third of IT leaders do not measure return on investment for wireless projects, a survey by Computer Weekly and BT has revealed.
The survey of IT professionals found that 94% of organisations with more than 500 employers were using wireless technology in some form. However, it found that 29% did not measure ROI.
Of those that did measure ROI, 53% focused on increased productivity, 38% used reduced operational costs and 34% took staff satisfaction as the key metric. Some respondents used more than one of these measures.
The survey found that security was by far the biggest headache for IT departments deploying wireless technology (59%), ahead of reliability (9%) and cost (8%).
Despite concerns about security, only 62% of companies had an end-user security policy for wireless working.
Ovum analyst Tony Cripps said, "Unless a business has a mobile strategy, it cannot measure return on investment." He said businesses needed to factor in how mobile technology is deployed into their overall IT strategy to assess possible benefits.
Too often mobile devices are introduced on an ad hoc basis or within departments, without the IT team being aware, he added.
