Mapping and agile

A lot of people here at ESSAP asks me about mapping and agile; I've opened a small review in the wiki of my favourite books that I republish here:

Tony Buzan is the inventor of mind mapping, the most powerful brainstorming technique for individuals I've ever seen. He has published a lot of books, and this is my favourite: simple and easy, you will start mind mapping after 10 minutes. After some practicing, you can turn yourself to dialogue mapping, a technique invented by Jeff Conklin. Dialogue mapping is more focused on team brainstorming. If I'm allowed to use it, redudancy in discussion is drastically reduced and meetings lasts less time with more achieved results.
