Abstract: Background: The software product lines (SPL) enable development teams to fully address a systematic reuse of shared assets to deliver a family of similar software products. Mobile applications are an obvious candidate for employing an SPL approach. This paper presents our research outcomes, based on empirical data from an industry-level development project. Two development teams were confronted with the same functionalities set to be delivered through a family of native mobile applications for Android and iOS. Methods: Empirical data was gathered before, during and after a year of full-time development. The data demonstrate the impact of a SPL approach by comparing the SPL and non-SPL multiple edition development. One family of products (Android apps) was developed using an SPL approach, while another (iOS apps), functionally the same, was developed without employing an SPL approach. The project generated a volume of raw and aggregated empirical data to support our research questions. Results: The paper reports a positive impact of an SPL approach on product quality (internal and external) and feature output per week. As data shows, it also increases the delivery of functionalities (240% in 6 more editions), while investing the same amount of effort needed for a single-edition development. As a result of system-supported separation of development and production code, developers had a high confidence in further development. On the other hand, the second team delivered less new functionalities, only two new application editions, and lower software quality than the team that manages multi-edition development by employing an SPL approach.

Abstract: The present thesis focuses on the development of a platform that will digitalize the volunteer log in Montenegro. To best understand the needs of our platform, we first need to gain a better understanding of what volunteering is, how it is carried out, and by whom, all taking into consideration the legal context. The currently existing solution for logging volunteer hours is highly impractical and seemingly has a low number of uses, indicating a need for renewal. In Montenegro, volunteering as well as any efforts volunteers put in have low recognition. Our solution is an easy-to-use, web platform developed in Flutter that enables seamless tracking of all volunteer services and activities and sets the foundation for a digital platform for everything related to volunteering on a national level. The research identifies the necessary functionalities through questionnaires for volunteers and interviews with volunteer managers and coordinators. Additionally, it explores the legal outline and how it navigates the desired outcome. Finally, an application is presented alongside the recommended improvements that will be added in the future. The developed platform allows for easy and comprehensive volunteer activity data tracking and helps streamline the volunteer management process. Its implementation would help with the national recognition of volunteer, as well as the skills and competencies one acquires through it.

Abstract: Although agile methods gained popularity and became globally widespread, developing secure software with agile methods remains a challenge. Method elements (i.e., roles, activities, and artifacts) that aim to increase software security on one hand can reduce the characteristic agility of agile methods on the other. The overall aim of this paper is to provide small- and medium-sized enterprises (SMEs) with the means to improve the sustainability of their software development process in terms of software security despite their limitations, such as low capacity and/or financial resources. Although software engineering literature offers various security elements, there is one key research gap that hinders the ability to provide such means. It remains unclear not only how much individual security elements contribute to software security but also how they impact the agility and costs of software development. To address the gap, we identified security elements found in the literature and evaluated them for their impact on software security, agility, and costs in an international study among practitioners. Finally, we developed a novel lightweight approach for evaluating agile methods from a security perspective. The developed approach can help SMEs to adapt their software development to their needs.

Abstract: In this work, we talk about artificial intelligence and its impact on software development. We define the AI concept, the software development process, and the various uses of AI in programming. We put a special focus on the ethical aspects of AI. In the empirical part, we analyzed the AI pair programming tool created by Microsoft called GitHub Copilot. We examine several usage examples, as well as the opinions of developers that have been using GitHub Copilot. We found that the AI pair programmer tool helps programmers increase productivity and automate mundane tasks to concentrate on more complex and interesting parts of software development. However, some programmers raise concerns about unethical concepts connected to the development of GitHub Copilot, implying violations of original code author copyrights. We discuss current licenses, other possible solutions, and the morality of building AI on open-sourced repositories. Moreover, many believe that the future will be increasingly intertwined with AI in all industries and that the only way to preserve (software development) jobs is to keep learning and being innovative and creative. Programmers say that almost certainly their job will not vanish because of AI advancement; only the scope of their work will change.
Keywords: AI, software development, ethics, AI pair programming, GitHub Copilot.

Abstract: The increasing use of agile methods for software development creates the need for these methods to become part of the education of future computer and information science engineers. On the other hand, teaching these methods gives us an opportunity to verify individual agile concepts and their effectiveness. For that reason, project work is an appropriate and frequently used form of teaching that enables students to get acquainted with agile methods and, at the same time, provides case studies for evaluating individual agile concepts. We describe our approach to teaching the Scrum agile method, within the software technology course, in cooperation with a software development company. Students were taught through work on a real project for which a list of requirements was submitted by the company. A co-worker of this company participated throughout the teaching period playing the role of customer's representative. During their work, students consistently used the Scrum method and at the end of each iteration they evaluated their experience by means of a questionnaire. In the article, the Scrum method is presented first, then a description of work on the project is given and finally the results of the survey are described.
