Links

On this page I have collected some links, which you may want to use in order to find additional material about XP.

Extreme Programming: One of the best introductions to XP on the web. The site is run by Don Wells, one of the XP gurus.
Ron Jeffries' website also contains many excellent documents about XP.
And there is also an English language Yahoo! discussion group on extreme programming.
The "Manifesto for Agile Software Development" documents the values, which are at the core of all agile methodologies.

Frank Westphals website contains a couple of excellent documents, which cover different aspects of XP. Furthermore, the website contains also information about services, such as training and consulting on XP.
Then there is the German language XP-Forum, a Yahoo!-discussion group, where everybody can ask questions, can contribute to answers or can just read the mails of other. Very informative!
In the Stuttgart/Germany area, there is the XP Users Group Stuttgart (XPUGS). The XPUGS organizes meetings on a regular basis. XP practioners and people, who want to become practitioners, have an opportunity to exchange experiences.
