Integrators (present and past), two questions:
Do you use time cards/time sheets? Physical versions? Web or PC based? None?
Second, how much do you break time tracking down? Do you just gather hours? Do you break it down into rough tasks, like cabling, termination, programming, training? Or do you have more detailed methods (camera termination, patch panel termination, power supply termination, etc.)?
For those using detailed tracking, what sorts of detail are you using? How do you break it down and do you think it's useful information?
