Understanding Object-Oriented Software Design Evolution in the Extreme Programming Process

提案编号：CCR-0097058题目：理解极限编程过程中面向对象软件设计的演变主要研究者：Wei Li摘要极限编程（XP）是一种新的软件过程，强调源代码作为主要的通信媒介，软件测试作为质量保证机制。本研究研究面向对象（OO）的软件设计的演变，并探讨了预测能力的软件metrics在XP过程中使用仔细记录的设计变更数据的两个商业Java系统开发使用的XP-likeprocess与日常（工作日）日志的设计变更和变更的努力。该项目分析收集的数据，并调查如何类设计，如CTA，CTM，NLM，WMC和LCOM等度量标准，从一个故事到下一个故事的演变：即，如果他们显示持续增长或其他。该项目还研究了在迭代周期结束时收集的OO指标是否可以通过使用多元线性回归来预测下一个周期中的重构、错误修复和新设计工作。这项研究的结果有助于我们理解客户需求是如何影响软件设计变更的，这些需求来自于XP过程中的客户小块（故事）。

Proposal Number: CCR-0097058Title: Understanding Object-Oriented Software Design Evolution in the Extreme Programming ProcessPrincipal Investigator: Wei LiAbstractExtreme Programming (XP) is a new software process emphasizing source codeas the main communication medium and software testing as the qualityassurance mechanism. This research studies object-oriented (OO) softwaredesign evolution and examines the predictive capability of software metricsin the XP process by using carefully logged design-change data on twocommercial Java systems developed using an XP-likeprocess with daily (working day) log on the design change and the changeeffort. This project analyzes the collected data and investigates how classdesign, as measured by metrics such as CTA, CTM, NLM, WMC, and LCOM, evolvesfrom one story to the next: i.e. if they show continuous growth or otherwise. Theproject also studies if the OO metrics collected at the end of an iterationcycle can predict the refactoring, error-fix, and new design efforts in thenext cycle by using multiple linear regression. The result from this studyhelps us understand how customer requirements, which come in small chunks(stories) from the customer in the XP process, affect software designchange.
