GPS is just a tool like a wrench or a keyboard, controlled by people. When not properly managed by competent people will create problems. Sounds like alot of wreches & GPS users currently out there are lacking the training and/or skills to handle the job properly. Managers need to lead by example, after all there job as managers include being leaders, so all you managers out there should look at how you conduct your business, you are the leaders! How your organaztion operates is a reflection on how you operate.
