An Investigation into quality assurance of the Open Source Software Development model

A thesis submitted in partial fulfilment of the requirements of the University of Wolverhampton for the degree of Doctor of PhilosophyThe Open Source Software Development (OSSD) model has launched products in rapid succession and with high quality, without following traditional quality practices of accepted software development models (Raymond 1999). Some OSSD projects challenge established quality assurance approaches, claiming to be successful through partial contrary techniques of standard software development. However, empirical studies of quality assurance practices for Open Source Software (OSS) are rare (Glass 2001). Therefore, further research is required to evaluate the quality assurance processes and methods within the OSSD model. The aim of this research is to improve the understanding of quality assurance practices under the OSSD model. The OSSD model is characterised by a collaborative, distributed development approach with public communication, free participation, free entry to the project for newcomers and unlimited access to the source code. The research examines applied quality assurance practices from a process view rather than from a product view. The research follows ideographic and nomothetic methodologies and adopts an antipositivist epistemological approach. An empirical research of applied quality assurance practices in OSS projects is conducted through the literature research. The survey research method is used to gain empirical evidence about applied practices. The findings are used to validate the theoretical knowledge and to obtain further expertise about practical approaches. The findings contribute to the development of a quality assurance framework for standard OSSD approaches. The result is an appropriate quality model with metrics that the requirements of the OSSD support. An ideographic approach with case studies is used to extend the body of knowledge and to assess the feasibility and applicability of the quality assurance framework. In conclusion, the study provides further understanding of the applied quality assurance processes under the OSSD model and shows how a quality assurance framework can support the development processes with guidelines and measurements

Leveraging Human Computation for Quality Assurance in Open Source Communities

Software developed under the open source development model (OSSD) has risen to significant importance over the recent decades. With more and more critical components being developed under the OSSD, the need for extensive quality assurance (QA) increases. This thesis investigates any potential for conducting formalized user testing through inexperienced volunteer community members under the OSSD. A human computation platform to aggregate such test results was designed and named open crowdsourced user-testing suite (OPEN-CUTS). A usability study of a prototype of OPEN-CUTS confirms the viability of this approach and points to potential future research questions.Software, die unter dem quelloffenen Entwicklungsmodell (Open Source Development Model, OSSD) entwickelt wird, hat in den letzten Jahrzehnten massiv an Bedeutung gewonnen. Immer mehr kritische Komponenten werden im Rahmen des OSSD entwickelt und der Bedarf für tiefgehende Qualitätssicherung (Quality Assurance, QA) steigt. Diese Arbeit untersucht, ob das OSSD Potenzial für formalisierte Nutzertests durch unerfahrene freiwillige Community-Mitglieder bietet. Eine Human Computation Plattform zur Sammlung solcher Testergebnisse wurde entworfen und trägt den Namen open crowdsourced user-testing suite (OPEN-CUTS). Eine mit einem Prototyp von OPEN-CUTS durchgeführte Benutzbarkeitsstudie bestätigt diesen Ansatz und zeigt mögliche zukünftige Forschungsfragen auf

Quality Assurance of Software Models - A Structured Quality Assurance Process Supported by a Flexible Tool Environment in the Eclipse Modeling Project

The paradigm of model-based software development (MBSD) has become more and more popular since it promises an increase in the efficiency and quality of software development. In this paradigm, software models play an increasingly important role and software quality and quality assurance consequently leads back to the quality and quality assurance of the involved models. The fundamental aim of this thesis is the definition of a structured syntax-oriented process for quality assurance of software models that can be adapted to project-specific and domain-specific needs. It is structured into two sub-processes: a process for the specification of project-specific model quality assurance techniques, and a process for applying them on concrete software models within a MBSD project. The approach concentrates on quality aspects to be checked on the abstract model syntax and is based on quality assurance techniques model metrics, smells, and refactorings well-known from literature. So far, these techniques are mostly considered in isolation only and therefore the proposed process integrates them in order to perform model quality assurance more systematically. Three example cases performing the process serve as proof-of-concept implementations and show its applicability, its flexibility, and hence its usefulness. Related to several issues concerning model quality assurance minor contributions of this thesis are (1) the definition of a quality model for model quality that consists of high-level quality attributes and low-level characteristics, (2) overviews on metrics, smells, and refactorings for UML class models including structured descriptions of each technique, and (3) an approach for composite model refactoring that concentrates on the specification of refactoring composition. Since manually reviewing models is time consuming and error prone, several tasks of the proposed process should consequently be automated. As a further main contribution, this thesis presents a flexible tool environment for model quality assurance which is based on the Eclipse Modeling Framework (EMF), a common open source technology in model-based software development. The tool set is part of the Eclipse Modeling Project (EMP) and belongs to the Eclipse incubation project EMF Refactor which is available under the Eclipse public license (EPL). The EMF Refactor framework supports both the model designer and the model reviewer by obtaining metrics reports, by checking for potential model deficiencies (called model smells) and by systematically restructuring models using refactorings. The functionality of EMF Refactor is integrated into standard tree-based EMF instance editors, graphical GMF-based editors as used by Papyrus UML, and textual editors provided by Xtext. Several experiments and studies show the suitability of the tools for supporting the techniques of the structured syntax-oriented model quality assurance process

Open educational resources : conversations in cyberspace

172 p. : ill. ; 25 cm.Libro ElectrónicoEducation systems today face two major challenges: expanding the reach of education and improving its quality. Traditional solutions will not suffice, especially in the context of today's knowledge-intensive societies. The Open Educational Resources movement offers one solution for extending the reach of education and expanding learning opportunities. The goal of the movement is to equalize access to knowledge worldwide through openly and freely available online high-quality content. Over the course of two years, the international community came together in a series of online discussion forums to discuss the concept of Open Educational Resources and its potential. This publication makes the background papers and reports from those discussions available in print.--Publisher's description.A first forum : presenting the open educational resources (OER) movement.

KAPTUR: technical analysis report

Led by the Visual Arts Data Service (VADS) and funded by the JISC Managing Research Data programme (2011-13) KAPTUR will discover, create and pilot a sectoral model of best practice in the management of research data in the visual arts in collaboration with four institutional partners: Glasgow School of Art; Goldsmiths, University of London; University for the Creative Arts; and University of the Arts London. This report is framed around the research question: which technical system is most suitable for managing visual arts research data? The first stage involved a literature review including information gathered through attendance at meetings and events, and Internet research, as well as information on projects from the previous round of JISCMRD funding (2009-11). During February and March 2012, the Technical Manager carried out interviews with the four KAPTUR Project Officers and also met with IT staff at each institution. This led to the creation of a user requirement document (Appendix A), which was then circulated to the project team for additional comments and feedback. The Technical Manager selected 17 systems to compare with the user requirement document (Appendix B). Five of the systems had similar scores so these were short-listed. The Technical Manager created an online form into which the Project Officers entered priority scores for each of the user requirements in order to calculate a more accurate score for each of the five short-listed systems (Appendix C) and this resulted in the choice of EPrints as the software for the KAPTUR project

Service Level Agreement-based GDPR Compliance and Security assurance in (multi)Cloud-based systems

Compliance with the new European General Data Protection Regulation (Regulation (EU) 2016/679) and security assurance are currently two major challenges of Cloud-based systems. GDPR compliance implies both privacy and security mechanisms definition, enforcement and control, including evidence collection. This paper presents a novel DevOps framework aimed at supporting Cloud consumers in designing, deploying and operating (multi)Cloud systems that include the necessary privacy and security controls for ensuring transparency to end-users, third parties in service provision (if any) and law enforcement authorities. The framework relies on the risk-driven specification at design time of privacy and security level objectives in the system Service Level Agreement (SLA) and in their continuous monitoring and enforcement at runtime.The research leading to these results has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 644429 and No 780351, MUSA project and ENACT project, respectively. We would also like to acknowledge all the members of the MUSA Consortium and ENACT Consortium for their valuable help

The Abertay Code Bar – unlocking access to university-generated computer games intellectual poperty

Progress report on a digital platform and dual licensing model developed to unlock access to a University repository of new and legacy computer games based Intellectual Property (IP) assets for educational and commercial use. The digital creative industries have been identified by a number of governments as a priority area in delivering sustainable economic growth. Code Bar is an innovation that allows digital products to be commercially successful beyond the end of the Dare competition or coursework submission. To be selected for Code Bar, game products must be well designed for both player and market; technically robust (i.e. operating consistently and reliably on a single/multiple platforms), and be free from ambiguity around 3rd party IP. We describe various technical, pedagogic and legal challenges in developing the digital platform, licensing model and packaging of computer games products for release through the platform. The model is extendable beyond computer games to other software products
