The XP and Agile Methods articles on-line vary enormously in quality, accuracy, and timeliness. Following are some of our favorites. Please let us know if you find that any of these links have gone stale.

This PC Magazine article is a brief but very good summary of the XP approach and practices. Even-handed and succinct.

This article from Wired article ruffled some feathers in the XP world, but we feel that on balance it provides a short, decent summary of some of the cultural changes that practices like Pair Programming are making in the software development mainstream. It cuts a few corners and some of the definitions are a bit off, but hey, it's Wired. :-)

This CIO Magazine article summarizes the approach of Agile Methods generally. Good snippets of advice ("Slash the Budget!").

This article, written by Agile methods guru Jim Highsmith, attempts to define what Agile Methods are, and gives a long and rich summary of their characteristics. It concludes by putting the Agile trend in historical perspective, as well as broader overall economic perspective. Jim can always be counted upon for such thought-provoking high-level analysis.

This Salon Magazine article is a nice journalistic day-in-the-life piece on how programmers themselves feel about XP.

This Cutter Consortium article is a survey summary concerning corporate attitudes toward agile development versus traditional methods. The conclusion seems to be that while agile methods are indeed better, they are not necessarily "winning" yet because some organizations find them threatening or difficult.

This article from the Australian version of CIO magazine is another good Agile Methods summary, with some good quotes.

In this artima.com article Bill Venners interviews Martin Fowler about the business case for refactoring and exhaustive testing -- both essential XP practices. See in particular Fowler's little aside about a fellow with an XP project that has had one bug so far in an entire year.

This XProgramming.com article by XP luminary Ron Jeffries provides a nice metaphor for the way in which XP gives project managers much better project control. Written in Ron's accustomed take-no-prisoners style.

Finally, here is another harvest of XP articles and books, in case you have not yet had your fill.
