And for the smart asses out there: yes I know that the above argument is itself vague. It's an example of a self-referential heuristic like Hofstader's Law (http://en.wikipedia.org/wiki/Hofstadters_law).
And many of the cases studies are about companies that were struggling with problems and managed to improve. The e-book specifically (and Lean Analytics, the book) aren't about understanding why startups failed, they're about how to use analytics to minimize failure and iterate past it.
