    Using Adapted Version of Hoshin Matrix for Selection of Agile Software Development Processes
    (CEUR-WS, 2018) Akarsu, Z.; Yılmaz, Murat; Metin, O.O.; Kuru, Y.Y.; Yilmaz, M.; Yazılım Mühendisliği
    According to Capability Maturity Model Integration for Development (CMMI-DEV), organizational process performance (OPP) area aims to establish and maintain a quantitative understanding of performance of selected processes. Many organizations have started their agile transformation to leverage the capabilities of their software development processes. In order to measure the effects of agile transformation, it is important to understand to what extent agile methods contribute to business objectives. Hoshin Matrix is a tool that provides a rationale for selecting processes identified for process performance analyses. Moreover, this rationale includes traceability from software development execution to business objectives. This study describes the implementation example of an adapted version of Hoshin Matrix at Huawei Turkey Research and Development Center which aims to establish its organizational quantitative quality and process performance objectives based on a set of business objectives. Our preliminary findings suggest that our OPP design may provide a guideline for software development organizations who are willing to adopt agile transformation and for those who would like to improve their software development processes.

    Designing Games for Improving the Software Development Process
    (Springer Verlag, 2015) Yilmaz, M.; Kosa, M.
    With the proliferation of relevant technologies that enables interactive social engagements, games became a strong driving power for next generation social environments. One of the reason for this is that there is an engaging nature in both digital and non-digital games, which is also suitable for creating serious kind of interactions such as teaching, training, learning, etc. Recently, researchers have started developing games or game-like applications in particular domains such as education, management, medicine. Although there are loads of empirical studies about game-based learning in general, scholars from information systems, computer science and software engineering domains have only a few attempts to develop and use the specific properties of games in their context-dependent environments. This workshop paper takes a look at some of these efforts and discusses about the pros and cons of such approaches. It is also argued that using well-designed, validated and pertinent non-digital games could be beneficial for improving the software development process. In particular, such approaches can be transformed into useful tools for teaching information systems and software engineering undergraduate or post-graduate students the fundamentals of information systems and software engineering. © Springer International Publishing Switzerland 2015.

    An Exploration of Individual Personality Types in Software Development
    (Springer Verlag, 2014) O'Connor, R.V.; Clarke, P.; Yilmaz, M.
    Previous research - using conventional psychometric questionnaires - has highlighted the importance of aligning compatible personality types in software development teams. However, there does not exist a dedicated, robust questionnaire instrument for revealing the pertinent personality types for software development practitioners. This study analyzes the validity and reliability of a 70-item (context dependent) personality-profiling questionnaire particularly developed to assess personality types of software practitioners. A systematic process of validation, using an iterative approach to questionnaire development, was employed. The questions were developed both with a qualitative analysis of interview data, and based on the opinions of expert reviewers who revised the items through a set of examination. To investigate how stable the questions and reproducible the results, we measured test-retest reliability of the instrument, yielding satisfactory results. The present study provided evidence for the construct validity of the instrument. Ultimately, an initial comparison of the results delivered by the instrument demonstrated positive correlations with the findings acquired with well-known personality assessment instrument, i.e. the big five personality questionnaire. © Springer-Verlag Berlin Heidelberg 2014.

    A Machine-Based Personality Oriented Team Recommender for Software Development Organizations
    (Springer Verlag, 2015) Al-Taei, A.; O’Connor, R.V.; Yilmaz, M.
    Hiring the right person for the right job is always a challenging task in software development landscapes. To bridge this gap, software firms start using psychometric instruments for investigating the personality types of software practitioners. In our previous research, we have developed an MBTI-like instrument to reveal the personality types of software practitioners. This study aims to develop a personality-based team recommender mechanism to improve the effectiveness of software teams. The mechanism is based on predicting the possible patterns of teams using a machine-based classifier. The classifier is trained with empirical data (e.g. personality types, job roles), which was collected from 52 software practitioners working on five different software teams. 12 software practitioners were selected for the testing process who were recommended by the classifier to work for these teams. The preliminary results suggest that a personality-based team recommender system may provide an effective approach as compared with ad-hoc methods of team formation in software development organizations. Ultimately, the overall performance of the proposed classifier was 83.3%. These findings seem acceptable especially for tasks of suggestion where individuals might be able to fit in more than one team. © Springer International Publishing Switzerland 2015.

    Interactive Three-Dimensional Virtual Environment To Reduce the Public Speaking Anxiety Levels of Novice Software Engineers
    (inst Engineering Technology-iet, 2019) Yilmaz, M.; Gulec, U.; Yilmaz, A. E.; Isler, V.; O'Connor, R. V.; Clarke, P.; Nazligul, M. Denizci; Denizci Nazligul, M.
    Software engineering is a set of activities that rely not only on the technical tasks but also require abilities focused on social duties such as daily meetings and product introduction presentations. However, engineers may experience elevated levels of anxiety when required to present their work in an unfamiliar environment. More specifically, they may suffer from public speaking anxiety even though they are supposed to be effective in those social tasks as well as in their engineering activities. Fortunately, previous studies suggest that the virtual exposure intervention is an effective strategy to reduce public speaking anxiety. In this study, an interactive three-dimensional virtual environment similar to real classrooms and auditoriums was developed to examine whether this might decrease the anxiety levels of novice software engineers. To compare the traditional and virtual exposure intervention, the sample set was divided equally into two groups including one experimental group and one control group. For 4 weeks, the virtual exposure intervention was conducted in the experimental group, whereas the cognitive behaviour therapy-based psychoeducation was used in the control group. The findings from authors' study illustrate that the virtual exposure intervention may represent an alternative solution to the traditional interventions for software engineers seeking to overcome public presentation anxiety.
