Book excerpt: If you are involved with any business or institution that currently uses IBM eServer iSeries, AS/400 servers, or Windows servers, then this book is for you. It will help you look inward at your own enterprise to evaluate your current state of e-business adoption. You will see where IBM is headed in terms of the future of e-business and learn how to take full advantage of their "on demand" strategy in your organization. You will learn how to leverage your existing investment in OS/400 and Windows computing infrastructure moving forward. You likely will see yourself somewhere in the "Top Ten Things That Tell You It's Time for a Change". Finally, you will read about the actual experiences of National Bancorp as they move down the e-business on demand adoption path. To help you stay current, this book comes with your personal password for accessing the companion Web site which offers up-to-the-minute iSeries news, "More on the Web" links, and additional iSeries resources.
