I wonder why some companies implement GPS and it is a great success while others use it and it fails miserably? Is it due to management or techs? Do the companies that fail use it solely for the purpose of "watching" road techs and why can't management figure this out, don't they research the idea before using it?

Does anyone feel like your management team is totally incompetent? Should you have had to be a road tech in the past to be a service manager? Does experience as a road tech prepare you better to manage road techs? Would a road tech turned service manager even want GPS on the service vans?
