We use the same system here. It has been up and running for just over 2.5 years. The system seems to work well as long as their is a joint game plan for the STO's. I have found that we struggle getting the same message to each shift. I think we have made some headway with a Bi-annual training Calendar. The hours and quality of training have goneway up since the inception of the program. I would be really interested to see how you tackle the beast.
