Apple's iPhone has reignited the debate over consumerisation - when new technologies are introduced into the consumer market and then brought into the enterprise market - with employees determined to integrate their personal devices with their enterprise applications. However, IT managers are reluctant to take on the responsibility of managing these devices.

This is according to a new report by Datamonitor. The report Enterprise Mobility: Trend Analysis to 2012, predicts global enterprise expenditure on mobile devices will grow from $6 billion in 2008 to an estimated $17 billion by 2012, which highlights the need for IT managers to begin to implement mobile device policies as ever more enterprises look to expand their mobile workforces. "Enterprises are fighting a losing battle against employees when it comes to mobile devices and they should consider supporting a limited selection of devices rather than banning them outright", says Daniel Okubo, technology analyst with Datamonitor and the report's author. "Allowing a range of the most popular devices will improve employee satisfaction and encourage more of them to embrace mobile devices and improve their productivity when away from the office." Enterprises are understandably concerned about ensuring the security of their data. In a survey conducted by Datamonitor to establish issues that are currently preventing enterprises from investing in mobility solutions, the majority of the 467 respondents rated security as the greatest barrier to adoption of mobility solutions. Traditionally enterprises have allocated devices, such as the Blackberry, to employees to enable them to check their email and be responsive when they are away from the office. However, as other mobile devices like the iPhone are increasingly popular among end users, enterprises are finding that employees want to be able to integrate their personal device with their corporate email account and other applications. For many people their mobile device is a personal thing which they want to customise and keep on their person. They do not want one device for personal use and an IT issued device for work. So far very few IT departments have yielded to these requests and are refusing to be responsible for managing such a wide variety of mobile devices. However, the iPhone has set a new standard for device usability and the trend of consumerisation is going to continue. "There is an element of fear of the unknown," says Okubo. "Enterprises question how security will be managed and whether mobility technologies will fit into their current IT infrastructure. Technology vendors have a role to play by properly addressing enterprise pain points." The key issue is that regardless of device, IT managers need to ensure they have a clear policy on mobile devices and at least the basic security capabilities to lock devices remotely, wipe them back to their factory setting and block certain applications being loaded. Employees must be made aware that it is important to report lost or stolen devices immediately, and they should not use their mobile devices to transfer sensitive company data. Carriers such as Vodafone have started realising the problems that many enterprises face in managing devices and have started offering hosted device management solutions. This means that if an employee loses their phone they can call their operator and they will wipe or lock it. Similarly if their phone is broken they can contact their operator who can remotely diagnose and fix their device and install updates. IT managers should ensure they have these capabilities either through traditional security vendors such as Sybase or for smaller enterprises, perhaps a hosted solution from a carrier is more efficient. Okubo concludes: "As more enterprises look to expand their mobile workforces and equip their employees with mobile devices, the issue of device management is going to become increasingly important. The popularity of mobile devices in the consumer markets is forcing enterprises to consider how best to manage these devices in the workplace and they need to ensure they have clear policies in place to manage employee expectations."
