Mikael Svahnberg reviewed Agile Software Requirements by Dean Leffingwell (The Agile software development series)
Review of 'Agile Software Requirements' on 'Goodreads'
4 stars
When reading other books about agile/lean, it has always chafed me that they focus exclusicely on the development team level, and assume that stories "magically" appear in the backlog. Instead, this book focus on what goes on in a large enteprise to put the stories into the backlog. As such it is one of the few books I've seen that shows how to scale agile/lean methodologies.
It is a bit wordy, but there are plenty of explaining pictures (some of which are gratuitous) so you can read it quite selectively if you are thus inclined.
