Project controlling was not in the focus of agile methods like eXtreme Programming (XP, cf. Beck, 1999) for a long time. Since agile methods are grass rooted, they derive from practitioners and focus on their needs. This chapter shows how to integrate lightweight mechanisms for project controlling into agile methods. The main idea is to combine (incomplete) hierarchical decomposition of systems with abstract measurements. The presented techniques address management needs without building barriers for developers.
