Empirical Evidence Principle and Joint Engagement Practice to Introduce XP.

Bringing software process change to an organisation is a real challenge. The authors have shown a sample attempt to carry out a process change and then reflected on its results and context. The present reflection points to a need for a set of principles and practices that would support the fragile process of introducing agility. For a start, the authors propose the Empirical Evidence principle exemplified using DICE® and the practice of Joint Engagement of the management and the developers. Both are results of a real-world process change case study in Poland. [ABSTRACT FROM AUTHOR]
