Keep in mind on the method of how customer satisfaction is graded. For example, JD Edwards is a complete crap benchmark.
I worked for a cellular call center. When I first hired on, they were paying big bucks to bring in consultants to improve CSR quality. After a couple months, we went from a very loose call standard to a very rigid script-like call standard. Keep in mind employee quality didn't change (would argue it went down) and the resolution for problems didn't change either. We now had to follow a rigid check list of things we needed to accomplish in each call. A year later, they were at the top of customer satisfaction for JD Edwards,out not due to training or customer resolution, but because they conformed to the agencies grading methods.
