If you are like me, in business related to call centers, but not really in call center business, this book is the one. After reading it, I got a new level of appreciation for the processes and complexity involved.
First part describes business aspect, goals, variables and how they influence goals. That's the part where I said, "It's not as simple as it seems".
Next one, on technology, gives you a review of supporting technologies. I personally knew most of the stuff, but it's a light reading and gives you a perspective how the call center views the technology.
Final two parts, on managing agent performance and call handling are valuable reading no matter what business you're in. Suggestions from the book can be applied outside of call centers, as well. And call handling... I think every employee that has a phone on their desk is the company's representative and should know how to handle calls. Dealing with angry customers, controlling the call, sales... it all goes beyond just call centre agents.
To summarize, if you want to get the big picture, see all the elements, understand them and understand how they interact, this is where you should start. Doesn't dwell too much on any individual subject (and doesn't go too much in-depth) and therefore, it is an easy informative reading. And that's what books from Dummies series are all about, aren't they?
