Title: Utilization and Development Contribution of Open Source Software in Japanese IT Companies: An Exploratory Study of the Effect on Business Growth

Authors: Terutaka Tansho (Shimane University, Japan), Tetsuo Noda (Shimane University, Japan)

Abstract: The usage of Open Source Software (OSS) has been more general these days and OSS are utilized in a wide range of business fields not only IT industries. Behind the expansion, there exist OSS development communities, where voluntary engineers dedicate their time and effort for the improvement. Considering development engineers in the companies as input resources, it is important to investigate the output of business growth. In this study, we conducted questionnaire survey to Japanese IT companies in 2013, and then analyzed the present state and relation between OSS utilization and development contribution. Our study revealed that Japanese IT companies are rather free riders of OSS, the volume of development contributions are far less than that of utilization. With regard to the effect on the business growth, the results of correlation analysis implicate that OSS utilization is related to the sales growth in the present term and that development contribution is related to the future growth of the employee number in the company. In order to explore the direct effect on the business growth, we constructed the models of multiple-logistic and logistic analyses, however, no direct and explicit determinants are found from the results of the analyses. Our research endeavors to investigate the OSS effect on the business growth are still on the way, but it is meaningful to provide the present state in numbers and hopefully this will lay some foundation for further study in this field.

Title: Socio-Technical Congruence in the Ruby Ecosystem

Abstract: Existing studies show that open source projects may enjoy high levels of socio-technical congruence despite their open and distributed character. Such observations are yet to be confirmed in the case of larger open source ecosystems in which developers contribute to different projects within the ecosystem. In this paper, we empirically study the relationships between the developer coordination activities and the project dependency structure in the Ruby ecosystem. Our motivation is to verify whether the ecosystem context maintains the high socio-technical congruence levels observed in many smaller scale FLOSS (Free/Libre Open Source Software) projects. Our study results show that the collaboration pattern among the developers in Ruby ecosystem is not necessarily shaped by the communication needs indicated by the dependencies among the ecosystem projects.

Title: The Impact of Automatic Crash Reports on Bug Triaging and Development in Mozilla

Authors: Iftekhar Ahmed (Oregon State University), Nitin Mohan (Oregon State University), Carlos Jensen (Oregon State University)

Abstract: Free/Open Source Software projects often rely on users submitting bug reports. However, reports submitted by novice users may lack information critical to developers, and the process may be intimidating and difficult. To gather more and better data, projects deploy automatic crash reporting tools, which capture stack traces and memory dumps when a crash occurs. These systems potentially generate large volumes of data, which may overwhelm developers, and their presence may discourage users from submitting traditional bug reports. In this paper, we examine Mozilla’s automatic crash reporting system and how it affects their bug triaging process. We find that fewer than 0.00009% of crash reports end up in a bug report, but as many as 2.33% of bug reports have data from crash reports added. Feedback from developers shows that despite some problems, these systems are valuable. We conclude with a discussion of the pros and cons of automatic crash reporting systems.
