At a client, today I’ve introduced the eXtreme Programmig methodology, with its values, principles, practices in a brown-bag session.
It has been an informal session, without slides, but we have used this video by the Kleer guys (in Spanish).
The video gives a high-level overview of what XP is. We also needed to cover the daily practices (e.g., TDD, pair programming, whole team)
After that, we’ve done a questions&answers round to solve the teammates' doubts
