Query: Not bad

Although I found this book to have some interesting points, I also found it to be a big promotion for Siebel's business. At some points I almost felt like I was reading a thick Siebel pamphlet. I was disappointed to find that the content I thought was most important was buried in the back of the book. If you have never read a book on e-business/e-commerce, this book is worth a try. If you are comfortable with the subject and are seeking more advanced content, skip this book.
