An Open Source Usability Maturity Model (OS-UMM)

User satisfaction has always been a major factor in the success of software, regardless of whether it is closed proprietary or open source software (OSS). In open source projects, usability aspects cannot be improved unless there are ways to test and measure them. Hence, the increasing popularity of open source projects among novice and non-technical users necessitates a usability evaluation methodology. Consequently, this paper presents a usability maturity model specifically aimed at usability-related issues for open source projects. In particular, the model examines the degree of coordination between open source projects and their usability aspects. The measuring instrument of the model contains factors that have been selected from four of our empirical studies, which examine the perspectives of OSS users, developers, contributors and the industry. In addition to presenting the usability maturity model, this paper discusses assessment questionnaires, a rating methodology and two case studies

AN M-LEARNING MATURITY MODEL FOR UNIVERSITIES AND HIGHER EDUCATIONAL INSTITUTES

An m-learning maturity model is put forward in this research to assess the mobile technology adoption rates in universities and higher educational institutes. The model is derived from Capability Maturity Model (CMM), which has been widely used in organizations to gauge the adoption of various new processes. Five levels of m-learning maturity are specified including preliminary, established, defined, structured, and continuous improvement. Each of these maturity levels is gauged through nine critical success factors (CSFs) in assessment questionnaires. The CSFs used in measuring instrument of the model are adopted from three of our previous empirical studies. Using an assessment questionnaire and a rating methodology, the study replicates the model to two universities to gauge their level of m-learning adoption. Thus, two case studies are presented to evaluate the applicability of the model. Hence the model provides a comprehensive approach, while opening new areas of future research

A pilot empirical study of applying a usability technique in an open source software project

Context: The growth in the number of non-technical open source software (OSS) application users and the escalating use of these applications have redoubled the need for, and interest in, developing usable OSS. OSS communities are unclear about which techniques to use in each development process activity. Objective: The aim of our research is to adapt a usability technique (visual brainstorming) to an OSS project and evaluate the feasibility of its application. Method: We used the case study research method to investigate technique application and participation in a project. To do this, we participated as volunteers in the HistoryCal project. Results: We identified adverse conditions that were an obstacle to technique application (like it was not easy to recruit OSS users to participate) and modified the technique to make it applicable. Conclusion: We conclude that these changes were helpful for applying the technique using web artifacts like blogsThis research was funded by the SENESCYT , Quevedo State Tech- nical University, TIN2014-52129-R and TIN2014-60490-P projects and the e-Madrid project (S2013/ICE-2715

Adoption of the personas technique in the open source software development process

The growth in the number of non-developer open source software (OSS) application users and the escalating use of these applications have led to the need and interest in developing usable OSS. OSS communities do not generally know how to apply usability techniques and are unclear about which techniques to use in each activity of the development process. The aim of our research is to adopt the Personas usability technique in the PSeInt OSS project and determine the feasibility of adapting the technique for application. To do this, we participated as volunteers in the project. We used the case study research method during technique application and participation in the community. As a result, we identified adverse conditions that were an obstacle to technique application and modified the technique to make it applicable. We can conclude from our experience that these changes were helpful for applying the technique, although it was not easy to recruit OSS users to participate in usability technique applicationThis research has been partly funded by several organizations, including the Government of Ecuador’s Secretariat of Higher Education, Science, Technology and Innovation (SENESCYT) through a scholarship and the State Technical University of Quevedo through doctoral training scholarships for university professors. Also this research was funded by the Spanish Ministry of Education, Culture and Sports FLEXOR and “Realizando Experimentos en la Industria del Software: Comprensión del Paso de Laboratorio a la Realidad” projects (TIN2014-52129-R and TIN2014-60490-P, respectively) and the eMadrid-CM “Investi-gación y Desarrollo de Tecnologías Educativas en la Comunidad de Madrid” project (S2013/ICE-2715

An Empirical Study of Critical Success Factors of Mobile Learning Platform from the Perspective of Instructors

Mobile learning is newest learning platform and based on the rapid rate of proliferation of mobile technology throughout the world is expected to grow at a rapid rate. However, the adoption of m-Learning is proceeding at a cautious rate. This mismatch in the rate of growth of the technology itself and the use of the technology in learning is a subject of extensive interest to researchers. However, research in the area has been mostly focused on understanding the success factors of the platform from learners’ perspective. In this research, we have conducted an extensive analysis of the extent to which various factors are considered to impact the success of mobile learning from the perspective of instructors. This is because instructors not only are one of the core users of the platform they also hold a great deal of influence in promoting the platform usage among learners. The results of the research were not found to be statistically significant showing that greater population size is required to assess various hypotheses. CC BY-NC-N

A systematic literature review of open source software quality assessment models

Background: Many open source software (OSS) quality assessment models are proposed and available in the litera- ture. However, there is little or no adoption of these models in practice. In order to guide the formulation of newer models so they can be acceptable by practitioners, there is need for clear discrimination of the existing models based on their speci c properties. Based on this, the aim of this study is to perform a systematic literature review to inves- tigate the properties of the existing OSS quality assessment models by classifying them with respect to their quality characteristics, the methodology they use for assessment, and their domain of application so as to guide the formula- tion and development of newer models. Searches in IEEE Xplore, ACM, Science Direct, Springer and Google Search is performed so as to retrieve all relevant primary studies in this regard. Journal and conference papers between the year 2003 and 2015 were considered since the rst known OSS quality model emerged in 2003. Results: A total of 19 OSS quality assessment model papers were selected. To select these models we have devel- oped assessment criteria to evaluate the quality of the existing studies. Quality assessment models are classi ed into ve categories based on the quality characteristics they possess namely: single-attribute, rounded category, community-only attribute, non-community attribute as well as the non-quality in use models. Our study re ects that software selection based on hierarchical structures is found to be the most popular selection method in the existing OSS quality assessment models. Furthermore, we found that majority (47%) of the existing models do not specify any domain of application. Conclusions: In conclusion, our study will be a valuable contribution to the community and helps the quality assess- ment model developers in formulating newer models and also to the practitioners (software evaluators) in selecting suitable OSS in the midst of alternatives
