After posting this morning about Serena Software allowing their employees to use Facebook, I decided to find out more information about it. At ZD Net, Jo McKendrick wrote this blog. The entire intranet was replaced with Facebook. McKendrick believes that the traditional intranets are expensive, stiff and hierarchal, while Facebook is free, flexible allows open communication. By utilizing the new apps features and creating groups, the flow of information throughout the company is trackable and manageable. It has also proved for better communication between managers and employees, even with the open door policy at Serena.
