A Computer Weekly survey indicates that organisations are more concerned about the impact of social networking on employee productivity than on security or reputation damage. As usual they are missing the bigger picture, which is the potential for fraud, social engineering, data leakage and, more importantly, the progressive transfer of influence over policy and decision making from corporate centres to networked staff. You might think that’s power to the people but it’s really power to well-organised minority interest groups. Social networking is also fiendishly difficult to police. It represents a step change in the erosion of barriers between business and personal lifestyles. That’s much, much harder to measure and manage than employee productivity.
