System Metaphor is one of the key practices of Extreme Programming (XP). Unfortunately, the System Metaphor practice is poorly understood, and is the practice XP teams most commonly choose to ignore. In this paper, we provide a small collection of patterns that teams can use to develop metaphors for their systems, and for evaluating system metaphors. We hope these patterns will encourage Extrem...

climate is the most important factor which control desertification .in order to detect climate changes in desert zones, time trend analysis is applied to extreme indices in kashan station using extreme climate index software (ecis). results show significant trends in extreme indices during the past decade 1995-2004 and the pronounced warming is associated with a negative trend in cold extremes....

Requirements engineering is a core practice within eXtreme Programming. Practising teams learn to not abandon any of the interconnected core practices. The continuous feedback teaches the team that they will develop at a faster and more reliable pace with the full set of practices. This paper shares an experience of how teams could accelerate development out of necessity, while maintaining thei...

This paper presents an early empirical study on Extreme Programming practices employing a qualitative action research method. The study was conducted on university students doing real commercial development projects to gain an insight into the problems faced by the new developers in adopting these agile practices. The aim of the study was to investigate the effects of the XP practices on the qu...

This paper presents a single case study reporting the experiences of introducing extreme programming (XP) in a small development project at Online Telemarketing in Lund, Sweden. The project was a success despite the fact that the customer had a poor idea of the system required at the start of the development. This success is partly due to the introduction of practically all of the XP practices....

The paper reports on the results of a recent study on student perceptions on agile practices. The study involved forty-five students enrolled in three different academic programs (Diploma, Bachelor’s and Master’s) in two institutions to determine their perceptions of the use of extreme programming practices in doing their design and coding assignments. Overwhelmingly, students’ experiences were...

super eciency data envelopment analysis(dea) model can be used in ranking the performanceof ecient decision making units(dmus). in dea, non-extreme ecient unitshave a super eciency score one and the existing super eciency dea models do notprovide a complete ranking about these units. in this paper, we will propose a methodfor ranking the performance of the extreme and non-extreme ecient u...

Introduction: Extreme-altitudes (5500 m/18045 ft and higher) pose environmental, psychophysiological, infrastructural, logistic, and ergonomic challenges that question explorer’s adaptability and mission-efficiency due to isolation, monotony, intimidating environment and terse health conditions. The assessment of an explorer’s comprehensive adaptability in extreme-altitudes is ...
