Abstract
XP emphasises underlying values as well as the more visible twelve practices. We examine the relationship between practices and values from the perspective of a model of culture and from an ethnographic study of mature XP practice. We conclude that the twelve practices are both significant and not significant. They are significant in that they do, in the reality of professional practice, give rise to a culture which embodies underlying XP values. They are not significant since both models of culture and the detailed manner in which the practices give rise to a culture suggest that alternative practices may achieve the same ends.
