Extreme Terseness: Some Languages Are More Agile than Others [PDF]
Stephan Taylor

While XP principles are independent of the languages in which software is developed, we can distinguish properties of programming languages that affect the agility of development. The history of software development in these languages foreshadows some of the characteristics of XP projects. To these linguistic communities, XP offers the prospect of rehabilitating styles of software development that fell into disrepute with the rise of software engineering. Conversely, these languages offer XP practitioners the possibility of radical condensation of the conversation between developer and customer.

SCRUM: An Extension Pattern Language for Hyperproductive Software Development [PDF]
Mike Beedle, Martine Devos, Yonat Sharon, Ken Schwaber and Jeff Sutherland

The patterns of the SCRUM development method are presented as an extension pattern language to the existing organizational pattern languages. In the last few years, the SCRUM development method has rapidly gained recognition as an effective tool to hyper-productive software development. However, when SCRUM patterns are combined with other existing organizational patterns, they lead to highly adaptive, yet well-structured software development organizations. Also, decomposing SCRUM into patterns can guide adoption of only those parts of SCRUM that are applicable to a specific situation.

Distributed eXtreme Programming [PDF]
Michael Kircher, Prashant Jain, Angelo Corsaro and David Levine

One of the key requirements of eXtreme Programming (XP) is strong and effective communication between the team members but to enable this strong level of communication among team members, XP emphasizes the need to have the team members physically located close to each other. Since this may not always be feasible, this paper addresses this issue by proposing a crosscutting idea called "Distributed eXtreme Programming" (DXP), which inherits the merits of XP and applies it in a distributed team environment. The author's experiences show that DXP can be both effective and rewarding in projects whose teams are geographically distributed.

This article is an introduction to articles about using Extreme Programming in the field.

Stabilizing the XP Process Using Specialized Tools [PDF]
Martin Lippert, Stefan Roock, Robert Tunkel and Henning Wolf

One problem with the XP development process is its fragility. If developers use the XP techniques in an unintended way or not at all, the XP process is likely to break down: The misused techniques affect the other XP techniques in a negative way, breaking the whole process. The authors believe that it is possible to stabilize the XP process using specialized artifacts to reify the XP techniques. They discuss the reification of the XP technique Continuous Integration using the JWAM IntegrationServer as an example and then present their experience with this tool and analyze its effects on the other XP techniques.

In this article the authors discuss how Orbix was maintained in which they ignored "good" engineering processes and practices. Two successful reengineering efforts and a series of infrastructure projects designed to improve the engineering practices were needed. Later the authors realized how close these efforts were tied to Extreme Programming.

Using Extreme Programming to Manage High-Risk Projects Successfully [PDF]
Martin Lippert and Heinz Züllighoven

Using XP enables it-Workplace Solutions GmbH & University of Hamburg (Germany) to deliver software on time and on budget, while supporting close communication between the (potential) customer and the development team as requirements changed daily. One to two releases per customer per week (two per day at the peak) indicate the flexibility and risk-minimizing capabilities of the process. This allowed optimal control and planning of the projects by the development company. The authors illustrate their experiences using one particular time-critical project.
