A
call center manager in New York is looking at the overall numbers
of her team to see which department deserves "department of the
month." Any department who gets 80% customer satisfaction or higher
is considered to be Blue Diamond.

Last year, the average customer satisfaction score for the
sales department was 70% and 10% standard deviation. The fraud
department averaged 68% customer satisfaction and 15% standard
deviation.
