When Joe comes by to light a fire to get ticket 14321 worked on, he doesn't need to; he can see that the DBA is working diligently, not surfing the web. Likewise, the estimates he gets from staff seem downright consistent, and he doesn't get the feeling that the project is in priority somewhere between lunch and checking email.
