If, on the other hand, you don't control access, determining utilization becomes difficult because of the variance in time online that is possible. Not all users are alike, but they can generally be categorized along departmental lines and by user type. Power users tend to be sophisticated users who work efficiently over remote access, sending and receiving data and getting offline fast. They don't want to be hobbled by slow data transfers. Thus, power users tend to spend less time connected, but connect more often.
New users tend to connect less often, but spend more time connected.
They aren't familiar enough with remote access to work efficiently and tend to read and respond to e-mail online. They spend little time online in the beginning. As users become more comfortable and experienced with remote access, they spend more time exploring other resources. New possibilities like synchronizing files, remote application and intranet technologies open up for them. Eventually, users learn to work more efficiently and spend less time online.
