Agile Development - Outside-In - Jeff Patton

I chatted for a while with Jeff Patton at xpday in London.  Very interesting - and very nice - guy.  His keynote presentation was fantastic.

He's currently writing a book and you can read it on-line as he increments (writes) and iterates (rewrites) it.  The book is called "Agile Development - Outside In - What you need to know to deliver useful, usable, and valuable software in an Agile environment". 

 

Looks fantastic based on my quick skim.
