In recent years the Extreme Programming (XP) community has grown substantially. Many XP projects have started and a substantial amount are already finished. As the interest in the XP approach is constantly increasing worldwide throughout all software intensive application domains, it was time to start a first survey on XP. This paper presents the results of 45 evaluated questionnaires that have...

Most of the contemporary projects require balance between agility and discipline. In the paper a software development and project management methodology called XPrince (eXtreme PRogramming IN Controlled Environments) is presented. It is a combination of XP, PRINCE2 and RUP. Moreover, some experiments and tools are described that create an important basis for the methodology.

We define a new class of positive and Lebesgue measurable functions in termsof their asymptotic behavior, which includes the class of regularly varying functions.We also characterize it by transformations, corresponding to generalized momentswhen these functions are random variables. We study the properties of this new classand discuss their applications to Extreme Value The...

As a result, the code base’s overall health degenerated and was salvaged only through two successful reengineering efforts and a series of infrastructure projects designed to improve overall engineering practices. It wasn’t until later that we realized how...

The scientific method serves as a good metaphor for several practices in Extreme Programming (XP). We explore the commonalities and differences and show that the scientific method, by analogy, can be used to better understand Test Driven Development (and vice versa).

This report summarises the results of a subworkshop on eXtreme Programming (XP)heldas part of NWPER’2002in Copenhagen, Denmark, August 2002. NWPER usually includes a number of “interactive subworkshops” such as this one, where the format is based on focused discussions rather than on the presentation of papers. The aim of this subworkshop was to gather people from academia and industry to discu...

This set of ten patterns is intended to complement the standard wisdom that can be gleaned from the Agile Development literature such as Kent Beck's Extreme Programming Explained[1]. It is directed primarily at those who are starting out with Extreme Programming or another agile methodology and might miss some subtle ideas. Once a team gains experience these patterns will become obvious, but in...

Pair programming is one of the twelve practices of Extreme Programming (XP) [1]. Pair programming is usually performed by programmers who are collocated—working in front of the same monitor. But the inevitability of distributed development of software gives rise to important questions: How effective is pair programming if the pairs are not physically next to each other? What if the programmers ...

[1] The observed trends in extreme precipitation events, and those in annual and seasonal mean precipitation in China during 1961–2001 are analyzed. The results show that the annual mean precipitation increases significantly in southwest, northwest, and east China, and decreases significantly in central, north and northeast China. The increasing trends in east China occurred mainly in summer, w...
