Development environments have changed drastically, development periods are shorter than ever and the number of team members has increased. Especially in open source software (OSS), a large number of developers contribute to OSS. OSS have difficulties in predicting or deciding when it will release. In order to assess recent software developments, we proposed a generalized software reliability model (GSRM) based on a
stochastic process, and compared GSRM with other models. In this paper, we focus on the release dates of OSS and the growth of faults (issues).

Abstract—Refactoring is widely recognized as a method to improve the internal qualities of source code. However, manual refactoring is time-consuming and error prone. Consequently, many tools to support automated refactoring have been suggested, but most support only unit and simple refactoring, making it difficult to perform composite refactoring (e.g., introducing a design pattern) where a refactoring set is applied at one position or the same refactoring operation is applied at multiple positions. In this paper, we propose a novel script language and its processor to describe how and where to refactor by a model expressing source code*1. Evaluations indicate that our language and processor allow refactoring steps to be described as scripts, which can be easily replayed and reused for multiple projects.

Software pattern is a general reusable solution to a commonly occurring problem within a given context while software development and management. Among various software patterns, organizational patterns are known as the basis for Agile software development movement, especially for Scrum and Extreme Programming. Patterns usually form a network having relationships among them to support users understand and utilize patterns efficiently and effectively. However little is known about the nature of such pattern networks, such as how are organizational patterns different from other patterns from the viewpoint of centrality. To clarify such characteristics of pattern networks and organizational patterns, we mine a network consisting 285 patterns from an existing world-largest online pattern repository called Portland Pattern Repository (PPR). By applying network analysis techniques to the mined network and careful review of the result, we revealed several interesting characteristics of the pattern network and organizational patterns.
