Whether you a.) heard something about SAFe and are not sure what it is, b.) want to learn more, or c.) just need to refresh your knowledge, here is a list of resources that will come in handy.
1. The Book
The seminal book “Agile Software Requirements – Lean Requirements Practices for Teams, Programs and the Enterprise” by Dean Leffingwell was first published in December 2010.

It was based on proven enterprise adoptions - none more so than Nokia.
