I'm not sure if I understand your question, but I'll give you my opinion anyway, 'cause that's what "Yahoo! Answers" is all about, right??. If you are already a customer service representative, you can gauge your effectiveness by how pleased your customers are with the level of service you have provided to them. Remember this though: there is no pleasing everyone! If the overwhelming majority are pleased, you're doing great!. As a 24 hour answering service telephone operator, I usually find that the best way to achieve effective cust srvc is by listening, understanding, empathizing, giving realistic solutions to people's problems or concerns and by being as nice to my callers as I would want them to be towards me. . Hope I didn't completely misunderstand your question and I hope it helps!
