When we think about what the offense (outbound call center) is doing, they have a very organized plan and need to follow that plan exactly, and that's supposed to get them the best results. The inbound call center is the opposite; they're like the defensive line on a team. Their goal is to defray problems that come in, solve problems, and put a road block in the way of anything that is making a customer unhappy. That's a completely different kind of strategy and approach. One requires a certain kind of pragmatic thinking and planning. The other requires a lot of innovative creativity to make sure that customers are happy when they leave the call. Now, in both cases what we see are companies and customer service reps who are very interested in making sure that customers are served best in both directions. When we talk about outbound callers, in many cases these are people who are making calls that are not necessarily completely welcomed, whereas the opposite is true of inbound call center reps, where customers are happy to finally get a human on the phone. So, that is the huge difference and one that I'm sure drives a lot of different behavior on the part of the call center reps themselves.
