On February 11-13 2001 seventeen people got together in Snowbird, Utah (USA) and from that meeting the Manifesto for Agile Software Development emerged. They recount some of the history of the creation of the manifesto here...
That's now more than 20 years ago and most people who "work agile" today will not be familiar with the historical context of the manifesto. The purpose of this site is to collect resources that provide that historical context, and commentaries on the manifesto and on Agile.
