In the spirit of simplicity, one of the basic XP Values, the number of artifacts in XP is fairly small. Actually, in XP we don't really talk about artifacts as such. Except for the production code, all other artifacts generated by the process imply work that is tangential to getting to the end goal, a running product. In theory, everything else should be considered as optional. The set of artifacts presented here is commonly used by XP teams to deliver software in an efficient manner. As a rule, try to limit the amount of effort put on any tangential work unless it can be proved to improve the process in some demonstrable way.

The XP artifacts are:

• Vision
• User Story
• Customer Test
• Release Plan
• Metaphor (System of Names)
• Iteration Plan
• Coding Standard
• Unit Test
• Production Code
• Build
