This research focuses on the comparison of outputs and outcomes related to the application of life cycle processes and how they are reflected in the resulting products. The research involved 15 teams developing comparable products using four different paradigms over one year and thus offers a way of assessing claims related to agile methods and XP. Very little comparative information is available for decision makers as virtually no similar studies exist. The work has resulted in three invited keynotes and is currently being replicated internationally as developers and managers seek further guidance about the selection and impact of process models
