Abstract. Applying changes to software engineering processes in organisations usually raises many problems of varying nature. Basing on a real-world 2-year project and a simultaneous process change initiative in Poland the authors studied those problems, their context, and the outcome. The reflection was a need for a set of principles and practices to help introduce eXtreme Programming (XP). In the paper the authors extend their preliminary set, consisting of the Empirical Evidence principle, exemplified using DICE R , and the practice of the Joint Engagement of management and the developers. This preliminary collection is being supplemented with the Capable Leader, as well as the Skilled and Motivated Team practices based on the DICE R framework as well. Key words: Extreme programming, Agile adoption, Process change, Software process improvement, DICE R framework. 1 Background The paper is based on a real-world software project and the attempt to bring agile practices to that projec...
