Introducing Extreme Programming (XP) to an industrial software development team usually involves technical and professional aspects as well as social and organizational ones. The introducing of a new software development method in general and XP in particular into a software project team that operates in the army emphasizes and extends these issues. In this paper we present a process through which XP has been introduced into a 60-members software development project at the Israeli Air Force. Focus is placed on an XP workshop conducted with ten officers who worked at different teams of the project. Specifically, we present the principles according to which we facilitated the workshop, the workshop agenda and data regarding the way the participants perceive some of the XP practices. Recently, the first XP team in this project has started to work the XP way.
