The net, used properly, makes people vastly more productive in just about
everything they do. Most knowledge workers - who need to be treated
like volunteers (because they are) don't respond well to intrusions like CyberSitter or NetNanny.
What's a CEO to do? I'm not sure there's a technology solution to this one
really. I think it comes down to giving people specific measurable
achievable relevant goals with a time limit and rewarding them for
success on those goals. You still need to understand the per-project
costs of course, but trying to eliminate reasonable amounts of
"water-cooler time" is probably counter productive.
