Here's a scenario: Tom's computer is acting up and getting a blue screen error a couple times a day. Obviously this is a problem because it drastically cuts into Tom's efficiency. Tom is a smart guy though, so his manager asks him to see if he can fix it before calling support and putting in a ticket. After all, tech support costs money. Tom spends about 4 hours across the next few days researching the issue, attempting a few things, and finally fixes it. Way to go Tom! You just saved the company money... or did you?
