Software quality has been an important but illusive concept for several decades, with experts different, sometimes conflicting, guidelines. Using an ecosystem of about 20,000 open source Java projects, this study will to try to discover correlations between open source component utilization and software quality metrics, in order to provide the strongest empirical evidence yet as to how the several metrics pertaining to software quality correlate with actual utilization of reusable components. This study will provide a scientific basis to some of the existing guidelines and to the dismissal of some others. If no correlations are found, this result will disrupt current conceptualizations of component quality, forcing researchers and developers to reassess their understanding of software quality and reusable components. Software being a foundation of modern society, and Open Source development being a significant movement in society at large, it is critical to gain a deeper understanding of software quality on a global scale, leading to the development of innovative tools and methods.The metrics used in this study are those defined by the SQO-OSS Quality Model. To understand correlations, the following method will be used. First the dependency graph will be built, capturing software dependencies at the global scale. This requires overcoming technical challenges in cleaning up and clustering the data, as real world projects contain all sorts of idiosyncrasies related to the use of external components. Second, a suite of utilization metrics will be developed using this global dependency graph that capture the depth and breadth of component usage by these projects. Finally, the SQO-OSS Quality metrics for a significant subset of projects in the data set will be computed and compared with the projects' utilization metrics in order to reveal the correlations.

几十年来，软件质量一直是一个重要但虚幻的概念，专家们有不同的、有时甚至是相互冲突的指导方针。本研究将利用约 20,000 个开源 Java 项目的生态系统，尝试发现开源组件利用率和软件质量指标之间的相关性，以便提供迄今为止最有力的经验证据，说明与软件质量相关的几个指标如何与软件质量相关。可重用组件的实际利用。这项研究将为现有的一些指南和其他一些指南的废除提供科学依据。如果没有发现相关性，这个结果将破坏当前组件质量的概念，迫使研究人员和开发人员重新评估他们对软件质量和可重用组件的理解。软件是现代社会的基础，而开源开发是整个社会的一项重大运动，因此在全球范围内深入了解软件质量至关重要，从而促进创新工具和方法的开发。使用的指标本研究中的内容是由 SQO-OSS 质量模型定义的。为了理解相关性，将使用以下方法。首先将构建依赖关系图，捕获全球范围内的软件依赖关系。这需要克服清理和集群数据方面的技术挑战，因为现实世界的项目包含与外部组件的使用相关的各种特性。其次，将使用此全局依赖关系图开发一套利用率指标，以捕获这些项目使用组件的深度和广度。最后，将计算数据集中重要项目子集的 SQO-OSS 质量指标，并将其与项目的利用率指标进行比较，以揭示相关性。
