Aamir,
I am afraid I do not quite agree with you. Tele-marketing is an art that is influenced a lot of factors, including the quality of leads and quality of technological setup. Rhythm apart, experience is something that is vital for an agent, especially to gain the art of selling. As agents gain more experience and spend more time on the telephone, they tend to improve more. Not to say that on any given day they will perform just because they are experienced.
As for verbatim and being effective, this is a strategy that should be developed based on the campaign and client requirements. Some agents are very good at selling, using their own vocabulary. But this has to be approved by QA, else the client may object.
Tele-marketing is an art, and requires both inborn skills and experience. Very few people can actually be come very good telemarkters, and those who do, should be valued, for they are an asset to any call center.
