Conclusion

DXP can efficiently integrate remote and mobile team members into the development process and is thus a valuable extension to traditional XP. In addition, it enables much more effective involvement of the customer compared with XP, especially in situations where it seems impossible to have an on-site customer.

DXP can therefore actively broaden the acceptance of XP as a lightweight though effective software development process. We are aware that a virtual meeting through computer-supported interaction can never replace direct human interaction. However, there are situations where such interaction is not feasible and where a form of XP can still be successfully employed.
