小团队结对编程实践研究和重构

结对编程是两个软件开发者在一台电脑前一起工作的一种编程实践，是极限编程方法的基础。对于软件产品的开发，人的知识是项目成功的重要因素。在组织的软件过程改进中，合适地引入结对编程，有利于知识的共享并营造团队合作的氛围，进而改善产品质量和缩短完成时间。不同规模的组织采用的软件过程的不同，对结对编程的引入会有不同的影响，所以在实践中结对编程的重构是必需的。基于小型组织和敏捷过程的项目实践，给出了一个切合实际的结对编程重构方案，进而提高小团队的生产效率。

交换编程——极限编程的延伸实践

结对编程是一种编程组队方法,在这种方法中要求两个程序员使用一台电脑在一起工作完成同一个任务。在软件开发中关于结对编程的价值正在进行着争论。目前在这个领域大量的知识都是离散的和无条理的。回顾这些可以看到绝大多数这方面的实验研究都是在大学环境中进行的。几乎没有在真实软件开发项目中详细审查下的结对编程被已存在的系统化实验研究过。因此,假设目前仍然没有纯粹的经验验证这种优势的存在。由于结对编程在表象上给人以浪费一个开发人员的感觉,所以,在很多软件企业中,很难得到推广实施。在本文的报告中,我们给出了一种有别于结对编程和传统的单人编程的团队组织形式,这种形式融合了结对编程促进团队内相互交流的好处,保持了团队的稳定性,同时采用了传统单人编程的形式,不给人以浪费人力的感觉。

Controlled experimentation on adaptations of pair programming

The use of agile methods is growing in industrial practice due to the documented benefits of increased software quality, shared programmer expertise, and user satisfaction. These methods include pair programming (two programmers working side-by-side producing the code) and test-driven approaches (test cases written first to prepare for coding). In practice, software development organizations adapt agile methods to their environment. The purpose of this research is to understand better the impacts of adapting these methods. We perform a set of controlled experiments to investigate how adaptations, or variations, to the pair programming method impact programming performance and user satisfaction. We find that method variations do influence programming results. In particular, better performance and satisfaction outcomes are achieved when the pair programming is performed in face-to-face versus virtual settings, in combination with the test-driven approach, and with more experienced programmers. We also find that limiting the extent of collaboration can be effective, especially when programmers are more experienced. These experimental results provide a rigorous foundation for deciding how to adapt pair programming methods into specific project contexts.

A comparative analysis of different gender pair combinations in pair programming

Over the last decade, there has been a steady stream of pair programming studies. However, one significant area of pair programming that has not received its due attention is gender. Considering the fact that pair programming is one of the major human-centric software development paradigms, this is a gap that needs to be addressed. This empirical study conducted quantitative and qualitative analyses of different gender pair combinations within pair programming context. Using a pool of university programming course students as the experiment participants, the study examined three gender pair types: female–female, female–male, and male–male. The result revealed that there was no significant gender difference in the pair programming coding output. But there were significant differences in the levels of pair compatibility and communication between the same gender pair type: female–female and male–male, and the mixed gender pair type, female–male. The post-experiment comments provide additional insights and details about gender in pair interactions.

Fuzzy Logic Based Group Maturity Rating for Software Performance Prediction

Driven by market requirements,software services organizations have adopted various software engineering process models (such as capability maturity model (CMM),capability maturity model integration (CMMI),ISO 9001:2000,etc.) and practice of the project management concepts defined in the project management body of knowledge.While this has definitely helped organizations to bring some methods into the software development madness,there always exists a demand for comparing various groups within the organization in terms of the practice of these defined process models.Even though there exist many metrics for comparison,considering the variety of projects in terms of technology,life cycle,etc.,finding a single metric that caters to this is a difficult task.This paper proposes a model for arriving at a rating on group maturity within the organization.Considering the linguistic or imprecise and uncertain nature of software measurements,fuzzy logic approach is used for the proposed model.Without the barriers like technology or life cycle difference,the proposed model helps the organization to compare different groups within it with reasonable precision.     

Search and Research on Economics of Pair Programming

This research aims to answer two research questions. Is pair programming more cost-effective than solo programming? In what situations is pair programming more cost-effective than solo programming and vice versa? In order to answer these, we adopted and extended economic models from past research. Two main conclusions can be drawn from our study. First, across the ranges of parameters studied, pair programming is more economically feasible only in a limited number of instances. Second, in order to achieve the economic benefit, pair programming either needs to have advantages in all three parameters (speed, defect, and defect removing) or have substantial advantages in two of them if on the other one pair is roughly equivalent to solo programming. We also identified specific parameter ranges for situations where a) pair programming is more economical, b) solo programming is more economical, and c) the two programming methods are equivalent. Implications of this research are discussed.
