I just read http://jpattonassociates.com/the-new-backlog/ and noticed that there’s a book on user story mapping by the same author, Jeff Patton: https://www.amazon.com/User-Story-Mapping-Discover-Product/dp/1491904909/ . I’ll probably listen to this podcast episode on the topic: http://talkingcode.com/podcast/episode-14-jeff-patton/
To give you something visual, here’s the “Story Map Concepts” page from http://jpattonassociates.com/story-mapping-quick-ref/ which i linked from the list of resources at http://jpattonassociates.com/user-story-mapping/
What do you think? Do you have experience with user story mapping? Do you recommend it? Thanks!
