摘要：
Agile development methods such as eXtreme Programming (XP) are increasingly adopted by software organizations and engineers to access its effectiveness and the benefits it promises. However, XP has some limitations in certain aspects pertaining to inter-group communication and teamwork. This issue is attributed mostly to the isolation among different pair-programmer groups. In this analysis, we study the impact of applying our solution of the Alternating Group Coordinator (AGC) on the effectiveness of XP. After giving an overview of XP and the issue which we address, we describe
the solution we devise and the method used to evaluate this solution through a statistical questionnaire and using it to develop a mathematical model that describes it.
