The idea behind this book is that if you look up one term in the glossary (95% of this book is a glossary) at the end of the entry for the term you looked up there is a list of additional terms to cross reference for a more in-depth understanding of the concepts presented. For example: You can look up EDI or Electronic Data Interchange. It will cross reference you to an entry for "PLATFORM". You can look up the term "Architecture" and it will also cross reference and guide you to read the entry for "PLATFORM". You can look up the term "Network" and it will also instruct you to cross reference the listing for the term, "PLATFORM". HOWEVER, WHEN YOU GO TO LOOK UP "PLATFORM", IT IS NOT LISTED ANYWHERE IN THE BOOK! IT IS ALSO NOT INCLUDED IN THE INDEX. The copy editors get paid big bucks to check out this kind of thing and they totally blew it!..Especially, Harvard Business School Press as the publisher should know better. You can expect this kind of thing to happen with the first edition must it should not happen in the 2nd edition.
