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....

We study the effects of firm’s credit condition on (1) labor market performance and (2) the inflation and unemployment relationship, in a new monetarist model. Better credit condition has positive impact on labor market as firms save on financing cost, improve profitability, and thus create more vacancies. Inflation increases the financing cost and thus discourages job creation. On the other ha...

This paper explores a reason why retailers pay such large merchant fees to credit card issuers. Credit cards as media of exchange are introduced to a New Monetarist model in which exchange occurs in alternating centralized and decentralized markets. Sellers who exert high (low) effort produce a good with a high (low) probability of being high quality. The quality of the good is revealed only af...

In a New Monetarist framework, we study the trade of indivisible goods under credit, divisible money and divisible asset in a frictional market. We show how indivisibility on the goods side, instead of the money or asset side, matters for equilibria. The bargaining solution generates a price that is independent of nominal interest rate, dividend value of the asset, or the number of active buyer...

Fiscal policy has been of significant size in Japan since the early 1990s, propelling Japan to the forefront of fiscally-challenged nations. However, the effect of fiscal policy has been disappointing. This paper discusses the various explanations provided by the literature (the argument that fiscal policy was effective; the argument that it was not effective, because of interest rate-based cro...

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...
