XP Customer Practices: A Grounded Theory

The customer is a critical role in XP, but almost all XP practices are presented for developers by developers.

Using grounded theory, we discovered eight customer practices used by successful XP teams: customer boot camp, customerpsilas apprentice, customer pairing, and programmerpsilas holiday support the well-being and effectiveness of customers; programmer on-site and road shows support team and organization interactions; and big picture up front and re-calibration support customers steering the whole project. By adopting these processes, XP customers and teams can work faster and more sustainably.
