Not invented here! is what the authors should scream when approached about this book. This is pl,atitudes, without substance, any connection to reality and proof what bullshit the Amazon review system produces. The best part of this book is the title, which the book does not live up to (nor the subtitle). The contents are pure crap!

This is a fun book to have in the bookshelf, but it has no utility whatsoever. In fact, if you need this book and believes it gives you any value, let me know so that I can make a concerted effort to avoid any ventures you are involved in.
