Essentials of the BSS/OSS industry
It's the only public published book on BSS/OSS industry i can find. Reading all TMF's documents is a big challenge, and reading this book is easier. It tells almost every key concepts about TMF's NGOSS program. I strongly recommend this book to everyone seting his/her career on OSS industry.

A timely and invaluable piece of work
Dr. Terplan has written a book (only one of the two available in thisarea) that will be invaluable for any person involved in either development or implementation of supports systems. The author obviously expects the reader to have a high level understanding of OSS related areas to appreciate and make the most this book. This book is a "must have" for all managers and consultants in the OSS segment.

Has potential to be great - lacks coherency & focus
This could have been *the* definitive reference on operational support systems. The author's uneven treatment of the subject and tendency to frequently go off topic or emphasize peripheral systems while leaving large gaps in the main subject have reduced this book to merely mediocre.
The strong points: the chapter on customer care and billing processes is remarkable. Here is a list of things that caught my attention and make this chapter so valuable: (1) the customer care maturity model is well thought out and serves as an excellent benchmarking tool, (2) the customer analysis and acquisition is on the mark, and (3) the customer interface management process and associated diagram comprise an excellent model for OSS processes. I also thought the way the author covered the problem handling process represents best practices, as does the section on SLA management. This is the stuff OSS is made of and it's covered both well and contains ideas and models in which service providers will be interested. The chapter provisioning and order processing is also strong and filled with excellent information for those who are seeking OSS-specific knowledge.
Weaknesses: Not only does this book overemphasize the network operations, which is important, but not central, but the author manages to drop this information into unexpected areas throughout the book. An example: Section 4.4 is an engrossing piece on the sales process that is succinct and filled with information, including tables and a diagram that reinforce the excellent information the author is imparting. Right in the middle of all this is a diagram that shows the use of a DMZ to separate intranets and extranets - not something anyone interested in sales processes cares about and is a big distraction. This happens throughout the book. Also, I agree with the comments made by a previous reviewer about wasting page count on product-specific information. This information needs to be moved to a web site where it can be maintained in an up-to-date fashion. Ironically, the publisher does this for other books. Finally, there are some major gaps: (1) no mention of the TeleManagement Forum, which is a global non-profit organization that is devoted to OSS. This organization has a technology integration map and numerous OSS-related processes that are De Facto standards in the OSS world, yet no mention of the organization and no mention of the wealth of material available that is directly related to OSS. (2) Section 7.4, which addresses migration from an existing to new billing system, misses some key considerations, which could have been developed into a discussion of strengths and weaknesses. For example, how do you segment and migrate subscribers? By CSA? Bill cycle? Region? Price plan? As the industry consolidates this particular issue keeps cropping up and a more in-depth treatment here is warranted. (3) No mention of TL 9000, which is an encompassing quality standard for telecommunications service providers. A portion of this standard applies directly to OSS.
Overall, this book contains some of the best information about OSS that has been collected and compiled into a single book. In fact, it's the only book on the subject. What is needed to make it great is a strong editor who understands OSS and who is not reticent about removing large pieces of superfluous material from this book. More information about standards that are directly related to OSS should also be included. If you work with operational support systems you really have no choice but to buy this book - I just hope that the next edition addresses the weaknesses.
