Understanding the context, structure, activities, and content of software development processes found in practice has been and remains a challenging problem. In the world of free/open source software development, discovering and understanding what processes are used in particular projects is important in determining how they are similar to or different from those advocated by the software engineering community. Prior studies have revealed that development processes in F/OSSD projects are different in a number of ways. In this paper, we describe how a variety of modeling perspectives and techniques are used to elicit, analyze, and validate software development processes found in F/OSSD projects, with examples drawn from studies of the software requirements process found in the NetBeans.org project.

Understanding the context, structure, activities, and content of software development processes found in practice has been and remains a challenging problem. In the world of free/open source software development (F/OSSD), discovering and understanding what processes are used in particular projects is important in determining how they are similar to or different from those advocated by the software engineering community. Prior studies have revealed that development processes in F/OSSD projects are different in a number of ways. In this article, we describe how a variety of modeling perspectives and techniques are used to elicit, analyze, and validate software development processes found in F/OSSD projects, with examples drawn from studies of the software requirements process found in the NetBeans.org project.

Process Metrics

There has been considerable discussion on the possible impacts of open source software development practices, especially in regard to the quality of the resulting software product. Recent studies have shown that analyzing data from source code repositories is an efficient way to gather information about project characteristics and programmers, showing that OSS projects are very heterogeneous in their team structures and software processes. However, one problem is that the resulting process metrics measuring attributes of the development process and of the development environment do not give any hints about the quality, complexity, or structure of the resulting software. Therefore, we expanded the analysis by calculating several product metrics, most of them specifically tailored to object-oriented software. We then analyzed the relationship between these product metrics and process metrics derived from a CVS repository. The aim was to establish whether different variants of open source development processes have a significant impact on the resulting software products. In particular we analyzed the impact on quality and design associated with the numbers of contributors and the amount of their work, using the GINI coefficient as a measure of inequality within the developer group.
