Query: lot's of info, little insight, nothing quantitative

"Secrets of.." reflects a lot of work by the four authors.Unfortunately a lot of information is repeated throughout several chapters, which make reading the book from front to end a bit strenuous.While the collection of data is impressive and the message is clear, the book lacks what I expected from it: a quantitative yardstick to evaluate the players in the software products market and the software service companies.
