Extreme Programming is based on core values of communication, simplicity, feedback, and courage. These are not just buzzwords: they pervade the behavior of XP practitioners and the choice of XP practices.

More than anything else, XP is about people, people coming together and working together to build software. The practices of XP are there to enable people to work together; the practices try never to get in the way of the human enterprise of building software that meets business needs. Thus, the practices of XP, while quite disciplined, are there to enable interactions among individuals, never to replace or interfere with those interactions.
