VEHICLE management software is an essential tool in risk management, not a means of spying on staff according to Aon's director for technology projects John Gaynor.

He said that despite complaints of 'Big Brother' watching employees' every move, the technology could help control costs and increase productivity, as well as provide valuable information on accident risk.

He added that employees were often hostile to having such technology fitted to their vehicles, but said if they were not doing anything wrong they had nothing to worry about.

He told delegates: 'Vehicle management information has always been about saving money, not spying on staff. We have no interest in spying on our drivers. Why should I care if I'm where I should be?

'Depending on the type of vehicles in the fleet, it could save hundreds of pounds a month, and if you are not saving this money by using the technology, your competitors could be.'

He said insurance costs would not automatically fall with the fitting of such systems, but there could be a benefit if fleets had a theft risk.

'Our objectives are asset protection,' he said. 'Ours is primarily a company car fleet and we had a number stolen, putting a big hole in fleet costs. Insurance costs were rising and it was up to us to make some clear strategic choices.

'We're not interested in checking on drivers to see what time they started work in the morning. But as well as cutting costs it allows us to monitor the effectiveness of driver training.'
