Proceedings of the 1st international workshop on software process education, training and professionalism (SPETP 2015)

These Proceedings contain the papers accepted for publication and presentation at the first 1st International Workshop on Software Process Education, Training and Professionalism (SPETP 2015) held in conjunction with the 15th International Conference on Software Process Improvement and Capability dEtermination (SPICE 2015), Gothenburg, Sweden, during June 15-17, 2015. During the 14th International Conference on Software Process Improvement and Capability dEtermination (SPICE 2014) held in Vilnius, Lithuania, at a post conference dinner, a group of key individuals from education and industry started to discuss the challenges faced for software process education, training and professionalism, especially with the background of the new modes of learning and teaching in higher education. Further discussions held post conference with key players in the relevant professional and personal certification fields led to a consensus that it is time for the industry to rise to the new challenges and set out in a manifesto a common vision for educators and trainers together with a set of recommendations to address the challenges faced. It was therefore agreed co-located the 1st International Workshop on Software Process Education, Training and Professionalism with the 15th International Conference on Software Process Improvement and Capability dEtermination. This workshop focused on the new challenges for and best practices in software process education, training and professionalism. The foundation for learning of software process should be part of a university or college education however software process is often treated as ‘add one’ module to the core curriculum. In a professional context, whilst there have been a number of initiatives focused on the certification related to the software process professional these have had little success for numerous reasons. Cooperation in education between industry, academia and professional bodies is paramount, together with the recognition of how the education world is changing and how education is resourced, delivered (with online and open learning) and taken up. Over the next 10 years on-line learning is projected to grow fifteen fold, accounting for 30% of all education provision, according to the recent report to the European Commission on New modes of learning and teaching in higher education. It is a great pleasure to see the varied contributions to this 1st International Workshop on Software Process Education, Training and Professionalism and we hope that our joint dedication, passion and innovation will lead to success for the profession through the publication of the manifesto as a key outcome from the workshop. On behalf of the SPETP 2015 conference Organizing Committee, we would like to thank all participants. Firstly all the authors, whose quality work is the essence of the conference, and the members of the Program Committee, who helped us with their expertise and diligence in reviewing all of the submissions. As we all know, organizing a conference requires the effort of many individuals. We wish to thank also all the members of our Organizing Committee, whose work and commitment were invaluable

From Bugs to Decision Support – Leveraging Historical Issue Reports in Software Evolution

Software developers in large projects work in complex information landscapes and staying on top of all relevant software artifacts is an acknowledged challenge. As software systems often evolve over many years, a large number of issue reports is typically managed during the lifetime of a system, representing the units of work needed for its improvement, e.g., defects to fix, requested features, or missing documentation. Efficient management of incoming issue reports requires the successful navigation of the information landscape of a project. In this thesis, we address two tasks involved in issue management: Issue Assignment (IA) and Change Impact Analysis (CIA). IA is the early task of allocating an issue report to a development team, and CIA is the subsequent activity of identifying how source code changes affect the existing software artifacts. While IA is fundamental in all large software projects, CIA is particularly important to safety-critical development. Our solution approach, grounded on surveys of industry practice as well as scientific literature, is to support navigation by combining information retrieval and machine learning into Recommendation Systems for Software Engineering (RSSE). While the sheer number of incoming issue reports might challenge the overview of a human developer, our techniques instead benefit from the availability of ever-growing training data. We leverage the volume of issue reports to develop accurate decision support for software evolution. We evaluate our proposals both by deploying an RSSE in two development teams, and by simulation scenarios, i.e., we assess the correctness of the RSSEs' output when replaying the historical inflow of issue reports. In total, more than 60,000 historical issue reports are involved in our studies, originating from the evolution of five proprietary systems for two companies. Our results show that RSSEs for both IA and CIA can help developers navigate large software projects, in terms of locating development teams and software artifacts. Finally, we discuss how to support the transfer of our results to industry, focusing on addressing the context dependency of our tool support by systematically tuning parameters to a specific operational setting

The Impact of Requirements on Systems Development Speed: A Multiple-Case Study in Automotive

Automotive\ua0manufacturers have historically adopted rigid\ua0requirements\ua0engineering processes. This allowed them to meet safety-critical\ua0requirements\ua0when producing\ua0a\ua0highly complex and differentiated product out of the integration of thousands of physical and software components. Nowadays, few software-related domains are as rapidly changing as the\ua0automotive\ua0industry.\ua0In\ua0particular, the needs of improving\ua0development\ua0speed\ua0are increasingly pushing companies\ua0in\ua0this domain toward new ways of developing software.\ua0In\ua0this paper, we investigate how the goal to increase\ua0development\ua0speed\ua0impacts how\ua0requirements\ua0are managed\ua0in\ua0the\ua0automotive\ua0domain. We start from\ua0a\ua0manager perspective, which we then complement with\ua0a\ua0more general perspective. We used\ua0a\ua0qualitative\ua0multiple-case\ua0study, organized\ua0in\ua0two steps.\ua0In\ua0the first step, we had 20 semi-structured interviews, at two\ua0automotive\ua0manufacturers. Our sampling strategy focuses on manager roles, complemented with technical specialists.\ua0In\ua0the second step, we validated our results with 12 more interviews, covering nine additional respondents and three recurring from the first step.\ua0In\ua0addition to validating our qualitative model, the second step of interviews broadens our perspective with technical experts and change managers. Our respondents indicate and rank six aspects of the current\ua0requirements\ua0engineering approach that\ua0impact\ua0development\ua0speed. These aspects include the negative\ua0impact\ua0of\ua0a\ua0requirements\ua0style dominated by safety concerns as well as decomposition of\ua0requirements\ua0over many levels of abstraction. Furthermore, the use of\ua0requirements\ua0as part of legal contracts with suppliers is seen as hindering fast collaboration. Six additional suggestions for potential improvements include domain-specific tooling, model-based\ua0requirements, test automation, and\ua0a\ua0combination of lightweight upfront\ua0requirements\ua0engineering preceding\ua0development\ua0with precise specifications post-development. Out of these 12 aspects, seven can likely be addressed as part of an ongoing agile transformation. We offer an empirical account of expectations and needs for new\ua0requirements\ua0engineering approaches\ua0in\ua0the\ua0automotive\ua0domain, necessary to coordinate hundreds of collaborating organizations developing software-intensive and potentially safety-critical\ua0systems

Model-Based Engineering of Collaborative Embedded Systems

This Open Access book presents the results of the "Collaborative Embedded Systems" (CrESt) project, aimed at adapting and complementing the methodology underlying modeling techniques developed to cope with the challenges of the dynamic structures of collaborative embedded systems (CESs) based on the SPES development methodology. In order to manage the high complexity of the individual systems and the dynamically formed interaction structures at runtime, advanced and powerful development methods are required that extend the current state of the art in the development of embedded systems and cyber-physical systems. The methodological contributions of the project support the effective and efficient development of CESs in dynamic and uncertain contexts, with special emphasis on the reliability and variability of individual systems and the creation of networks of such systems at runtime. The project was funded by the German Federal Ministry of Education and Research (BMBF), and the case studies are therefore selected from areas that are highly relevant for Germany’s economy (automotive, industrial production, power generation, and robotics). It also supports the digitalization of complex and transformable industrial plants in the context of the German government's "Industry 4.0" initiative, and the project results provide a solid foundation for implementing the German government's high-tech strategy "Innovations for Germany" in the coming years

Technical Debt: An empirical investigation of its harmfulness and on management strategies in industry

Background: In order to survive in today\u27s fast-growing and ever fast-changing business environment, software companies need to continuously deliver customer value, both from a short- and long-term perspective. However, the consequences of potential long-term and far-reaching negative effects of shortcuts and quick fixes made during the software development lifecycle, described as Technical Debt (TD), can impede the software development process.Objective: The overarching goal of this Ph.D. thesis is twofold. The first goal is to empirically study and understand in what way and to what extent, TD influences today’s software development work, specifically with the intention to provide more quantitative insight into the field. Second, to understand which different initiatives can reduce the negative effects of TD and also which factors are important to consider when implementing such initiatives.Method: To achieve the objectives, a combination of both quantitative and qualitative research methodologies are used, including interviews, surveys, a systematic literature review, a longitudinal study, analysis of documents, correlation analysis, and statistical tests. In seven of the eleven studies included in this Ph.D. thesis, a combination of multiple research methods are used to achieve high validity.Results: We present results showing that software suffering from TD will cause various negative effects on both the software and the developing process. These negative effects are illustrated from a technical, financial, and a developer’s working situational perspective. These studies also identify several initiatives that can be undertaken in order to reduce the negative effects of TD.Conclusion: The results show that software developers report that they waste 23% of their working time due to experiencing TD and that TD required them to perform additional time-consuming work activities. This study also shows that, compared to all types of TD, architectural TD has the greatest negative impact on daily software development work and that TD has negative effects on several different software quality attributes. Further, the results show that TD reduces developer morale. Moreover, the findings show that intentionally introducing TD in startup companies can allow the startups to cut development time, enabling faster feedback and increased revenue, preserve resources, and decrease risk and thereby contribute to beneficial\ua0effects. This study also identifies several initiatives that can be undertaken in order to reduce the negative effects of TD, such as the introduction of a tracking process where the TD items are introduced in an official backlog. The finding also indicates that there is an unfulfilled potential regarding how managers can influence the manner in which software practitioners address TD

Towards more effective testing of communications-critical large scale systems

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.A publication based on the research from this thesis has been published and can be cited as Nabulsi, MA and Hierons, RM (2014), A new test framework for communications-critical large scale systems, IEEE Software, In press. The published version can be accessed via the link below.None of today’s large scale systems could function without the reliable availability of a varied range of network communications capabilities. Whilst software, hardware and communications technologies have been advancing throughout the past two decades, the methods commonly used by industry for testing large scale systems which incorporate critical communications interfaces have not kept pace. This thesis argues for the need for a specifically tailored framework to achieve effective testing of communications-critical large scale systems (CCLSS). The thesis initially discusses how generic test approaches are leading to inefficient and costly test activities in industry. The thesis then presents the form and features of an alternative CCLSS domain-specific test framework, develops its ideas further into a detailed and structured test approach for one of its layers, and then provides a detailed example of how this framework can be applied using a real-life case study. The thesis concludes with a qualitative as well a simulation-based evaluation of the framework’s benefits observed during the case study and an evaluation by expert external participants considering whether similar benefits can be realised if the framework is adopted for the testing of other comparable systems. Requirements data from a second CCLSS is included in the evaluation by external participants as a second smaller case study

DEVELOPMENT OF A QUALITY MANAGEMENT ASSESSMENT TOOL TO EVALUATE SOFTWARE USING SOFTWARE QUALITY MANAGEMENT BEST PRACTICES

Organizations are constantly in search of competitive advantages in today’s complex global marketplace through improvement of quality, better affordability, and quicker delivery of products and services. This is significantly true for software as a product and service. With other things being equal, the quality of software will impact consumers, organizations, and nations. The quality and efficiency of the process utilized to create and deploy software can result in cost and schedule overruns, cancelled projects, loss of revenue, loss of market share, and loss of consumer confidence. Hence, it behooves us to constantly explore quality management strategies to deliver high quality software quickly at an affordable price. This research identifies software quality management best practices derived from scholarly literature using bibliometric techniques in conjunction with literature review, synthesizes these best practices into an assessment tool for industrial practitioners, refines the assessment tool based on academic expert review, further refines the assessment tool based on a pilot test with industry experts, and undertakes industry expert validation. Key elements of this software quality assessment tool include issues dealing with people, organizational environment, process, and technology best practices. Additionally, weights were assigned to issues of people, organizational environment, process, and technology best practices based on their relative importance, to calculate an overall weighted score for organizations to evaluate where they stand with respect to their peers in pursuing the business of producing quality software. This research study indicates that people best practices carry 40% of overall weight, organizational best v practices carry 30% of overall weight, process best practices carry 15% of overall weight, and technology best practices carry 15% of overall weight. The assessment tool that is developed will be valuable to organizations that seek to take advantage of rapid innovations in pursuing higher software quality. These organizations can use the assessment tool for implementing best practices based on the latest cutting edge management strategies that can lead to improved software quality and other competitive advantages in the global marketplace. This research contributed to the current academic literature in software quality by presenting a quality assessment tool based on software quality management best practices, contributed to the body of knowledge on software quality management, and expanded the knowledgebase on quality management practices. This research also contributed to current professional practice by incorporating software quality management best practices into a quality management assessment tool to evaluate software
