    Towards a Role Playing Game for Exploring the Roles in Scrum To Improve Collaboration Problems
    (Springer international Publishing Ag, 2018) Metin, Ozgun Onat; Gungor, Deniz; Yilmaz, Murat; Akarsu, Zulal
    Scrum is the most popular, useful and lightweight framework based on agile software development philosophy. In particular, software development organizations are willing to transform their software development culture to benefit from its fruitful practices. In addition, it is almost inevitable for the organizations with historical development practices to face many dysfunctions during transformation phase, which is normal and expected. It is important to uncover, analyze and solve these dysfunctions, which may take some time. One of the problems organizations may encounter is the confusion and misapplication of the roles in Scrum. This dysfunction creates problems from task creation, follow-up, taking responsibility to collaboration problems in the project. The goal of this study is to address such situations using an interactive role playing game-based approach among team members to improve collaboration.

    The Impact of Situational Context on Software Process: a Case Study of a Very Small-Sized Company in the Online Advertising Domain
    (Springer international Publishing Ag, 2018) Yilmaz, Murat; O'Connor, Rory V.; Clarke, Paul M.; Giray, Gorkem; O’Connor, Rory V.
    A primary concern of software development is selecting a suitable methodology to implement a software project. However, this selection is affected by many factors, with evidence suggesting that a specific set of factors defines a specific situational context for a project. This situational context leads to a project-specific software process. In this paper, we report on our analysis of a very small-sized company's current software process based on a reference framework that identifies the factors of a situational context. The outcome of our case study confirms the earlier findings that a software process is highly dependent on situational factors. The company has a suitable situational context (such as very small-sized, experienced, skilled, cohesive team with low turnover) to apply agile practices and its software process is more close to an agile rather than plan-driven approach. Moreover, the company is continuously adopting its software process to the situational factors changing from project to project and over time.

    Evaluation of Semantic Relatedness Measures for Turkish Language
    (Springer international Publishing Ag, 2018) Sopaoglu, Ugur; Ercan, Gonenc
    The problem of quantifying semantic relatedness level of two words is a fundamental sub-task for many natural language processing systems. While there is a large body of research on measuring semantic relatedness in the English language, the literature lacks detailed analysis for these methods in agglutinative languages. In this research, two new evaluation resources for the Turkish language are constructed. An extensive set of experiments involving multiple tasks: word association, semantic categorization, and automatic WordNet relationship discovery are performed to evaluate different semantic relatedness measures in the Turkish language. As Turkish is an agglutinative language, the morphological processing component is important for distributional similarity algorithms. For languages with rich morphological variations and productivity, methods ranging from simple stemming strategies to morphological disambiguation exists. In our experiments, different morphological processing methods for the Turkish language are investigated.

    Cengo: a Web-Based Serious Game To Increase the Programming Knowledge Levels of Computer Engineering Students
    (Springer international Publishing Ag, 2019) Yalcin, Alihan Dogus; O'Connor, Rory V.; Clarke, Paul M.; Gulec, Ulas; Yilmaz, Murat; O’Connor, Rory V.
    In recent years there has been an increased use of serious games to help increase the level of knowledge and experience of individuals working in different domains. In particular serious games for educational purposes have been used in many domains including software engineering and computer science [1]. Hence, this study proposes a quantitative research approach to increase the programming knowledge levels of the first-year undergraduate students at computer engineering departments. For this aim, a responsive web platform was developed to teach the syntax and logic of the C programming language by using game elements. This environment provided students with an ability to independently investigate the C programming language continuously since the platform is always accessible. To better understand the effectiveness of the designed environment, 10 first-year computer engineering students were selected as a pilot experimental group. According to the results obtained from the user tests, this game can be used as an educational tool, which supports the traditional training methods, to increase the knowledge levels of students about the syntax and logic of the C programming language.

    Applying Blockchain To Improve the Integrity of the Software Development Process
    (Springer international Publishing Ag, 2019) Tuzun, Eray; Gulec, Ulas; O'Connor, Rory V.; Clarke, Paul M.; Yilmaz, Murat; Tasel, Serdar; O’Connor, Rory V.
    Software development is a complex endeavor that encompasses application and implementation layers with functional (refers to what is done) and non-functional (how is done) aspects. The efforts to scale agile software development practices are not wholly able to address issues such as integrity, which is a crucial non-functional aspect of the software development process. However, if we consider most software failures are Byzantine failures (i.e., where components may fail and there is imperfect information on which a component has failed.) that might impair the operation but do not completely disable the production line. In this paper, we assume software practitioners who cause defects as Byzantine participants and claim that most software failures can be mitigated by viewing software development as the Byzantine Generals Problem. Consequently, we propose a test-driven incentive mechanism based on a blockchain concept to orchestrate the software development process where production is controlled by a similar infrastructure based on the working principles of blockchain. We discuss the model that integrates blockchain with the software development process, and provide some recommendations for future work to address the issues while orchestrating software production.

    An Experimental Study on Decomposition: Process First or Structure First
    (Springer international Publishing Ag, 2019) Suloglu, Selma; Kaya, M. Cagri; Karamanlioglu, Alper; Tokdemir, Gul; Dogru, Ali H.; Cetinkaya, Anil; Cagri Kaya, M.
    This article explores the answer to the question of considering the process or the structure dimensions earlier, in software development where decomposition is a preferred technique for top-down model construction. In this research, an experimental study was conducted to observe which software modeling practice is more convenient: process or structural modeling, for the beginning. The study was conducted in different courses that include software modeling where students work within groups to model a system with predefined requirements. The students used Business Process Modeling Notation and Component-Oriented Software Engineering Modeling Language modeling tools. Observations based on the results are analyzed and discussed. The results seem to prioritize the process dimension.

    Adopting Augmented Reality for the Purpose of Software Development Process Training and Improvement: an Exploration
    (Springer international Publishing Ag, 2018) Oge, Irem; Orkun, Bora; Yilmaz, Murat; Tuzun, Eray; Clarke, Paul; O'Connor, Rory V.; Ohri, Ipek; O’Connor, Rory V.
    Augmented reality (AR) is a technological field of study that bridges the physical and digital world together with a view to improving user experience. AR holds great potential to change the delivery of software services or software process improvement by utilizing a specific set of components. The purpose of this exploratory study is to propose an integration framework to support AR for improving the onboarding process, notably in introducing new hires to the development process while performing their daily tasks. In addition, it also aims to enhance the software development workflow process using AR. Similar to a GPS device that can guide you from point A to point B, our goal is to create software artifacts like navigation components where software teams may benefit from digitally enhanced working conditions provided using AR. After conducting a review in the literature, we confirmed that there is lack of studies about the combination of augmented reality with software engineering disciplines for onboarding. In this paper, we formalized our approach based on the benefits of AR. Ultimately; we propose an AR-based preliminary model for improving the software development process.

    A Serious Game for Improving the Decision Making Skills and Knowledge Levels of Turkish Football Referees According To the Laws of the Game
    (Springer international Publishing Ag, 2016) Gulec, Ulas; Yilmaz, Murat
    Digital game-based learning environments provide emerging opportunities to overcome learning barriers by combining newly developed technologies and traditional game design. This study proposes a quantitative research approach supported by expert validation interviews to designing a game-based learning framework. The goal is to improve the learning experience and decision-making skills of soccer referees in Turkey. A serious game was developed and tested on a group of referees (N = 54). The assessment results of these referees were compared with two sample t-test and the Wilcoxon signed-ranked test for both the experimental group and the control group. The findings of the current study confirmed that a game-based learning environment has greater merit over the paper-based alternatives.
