Assessing the Open Source Development Processes Using OMM

The assessment of development practices in Free Libre Open Source Software (FLOSS) projects can contribute to the improvement of the development process by identifying poor practices and providing a list of necessary practices. Available assessment methods (e.g., Capability Maturity Model Integration (CMMI)) do not address sufficiently FLOSS-specific aspects (e.g., geographically distributed development, importance of the contributions, reputation of the project, etc.). We present a FLOSS-focused, CMMI-like assessment/improvement model: the QualiPSo Open Source Maturity Model (OMM). OMM focuses on the development process. This makes it different from existing assessment models that are focused on the assessment of the product. We have assessed six FLOSS projects using OMM. Three projects were started and led by a software company, and three are developed by three different FLOSS communities. We identified poorly addressed development activities as the number of commit/bug reports, the external contributions, and the risk management. The results showed that FLOSS projects led by companies adopt standard project management approaches as product planning, design definition, and testing, that are less often addressed by community led FLOSS projects. The OMM is valuable for both the FLOSS community, by identifying critical development activities necessary to be improved, and for potential users that can better decide which product to adopt

Overview on Trust in Large FLOSS Communities

Abstract. The paper presents a survey of mature Free/Libre Open Source Software communities. The main focus of the survey is the collection of data related to the practices of these communities related to trust elements in their products. The survey is carried out using a structured questionnaire about thoughts and practices followed by Free/Libre Open Source Software communities. The survey focuses on the analysis of the development processes adopted by such communities. The results of the survey confirms basic ideas related to Free/Libre Open Source Software and explains in more detail specific issues related to trust and trustworthiness of the Free/Libre Open Source Software development process

Two Evolution Indicators for FOSS Projects

Part 1: Full PapersInternational audienceIn this paper we introduce two project evolution indicators. One is showing an increase of downloads of the project and therefore a growing interest of users in the results of the project. The second indicator is predicting the future evolution of the project with the submission of new revisions to the concurrent versioning system. Both indicators can provide evidence of the sustainability of a software project. We used the General Linear Model method to statistically formulate the two linear equations that can be used to predict the two indicators. The predicting equations were build by using two stratified data samples one of 760 projects and the second of 880 projects extracted from the SourceForge repository. The six metrics included into the final version of the two models were extracted from a set of thirty project and product metrics as: the number of downloads, the number of developers, etc. We have validated the discriminant and the concurrent validity of the two models by using different statistical tests as the goodness-of-fit and we have used the two models to predict the indicators on two hold-out validation samples. The model predicting the increment of downloads was correct in 75 percent of the cases, the model predicting the submission of new revisions was correct in 93 percent of the cases

Adoption of OSS Development Practices by the Software Industry: A Survey

Part 1: PapersInternational audienceThe paper presents a survey of aspects related to the adoption of Open Source Software by the software industry. The aim of this study was to collect data related to practices and elements in the development process of companies that influence the trust in the quality of the product by potential adopters. The work is part of the research done inside the QualiPSo project and was carried out using a qualitative study based on a structured questionnaire focused on perceptions of experts and development practices used by companies involved in the Open Source Software industry. The results of the survey confirm intuitive concerns related to the adoption of Open Source Software as: the selection of the license, the quality issues addressed, and the development process tasks inside Open Source Software projects. The study uncovered specific aspects related to trust and trustworthiness of the Open Source Software development process that we did not find in previous studies as: the standards implemented by the OSS project, the project’s roadmap is respected, and the communication channels that are available
