I was frankly expecting more of this book. The author superficially covers the basics of the OneWorld software architecture and the very basic of navigation and usage. Being titled "Implementing", I was expecting to find real life information on hardware sizing, what to do and not to do to successfully implement the software. There was not much more than what you could find in J.D.Edwards documentation and available Knowledge Garden papers. Also, anybody who has worked with this software knows that there is still a lot to do to make it as reliable as marketing hype pretend it to be. One would expect some objectivity from a third party, as good as the software really is. Wise advices like waiting for implementing ESU and service pack, making sure you have the appropriate skills around to do an implementation are slipped away from the content. If you have not worked with OneWorld before, and are planning to learn and implement the software, this is an acceptable introductory textbook. However, if you are looking for more in-depth coverage of real life issues with this software, you will have to look some place else.
