John addressed this question in the Wall Street Journal recently. Here's what he has to say.
Yes: It Is Inevitable
Fight it all you want, but employees are going to be bringing their own smartphones, tablets and other technology to work with them. So it's time to stop resisting and start preparing.
Most of the organizations I worked with or for over the past 40 years had strict rules about technology. They kept tight control over what hardware and software workers could use, believing it would be easier to secure and manage that way. Some even went so far as to lock down their technologies, meaning employees couldn't do things like change user preferences.
Such an approach seemed to make sense, considering the challenges related to fighting viruses and malware, as well as the need to secure business data and make sure company computers weren't used inappropriately.
But talk to corporate IT people, and they'll tell you maintaining such tight control these days has become a real pain.
