    Abstract Conceptual Database Model Approach
    (2013) Çağıltay, Nergiz; Çaĝiltay, N.E.; Topalli, D.; Tokdemir, Gül; Aykaç, Y.E.; Tokdemir, G.; Yazılım Mühendisliği; Bilgisayar Mühendisliği
    One of the main objectives of the software engineers is to provide software related solutions for social problems and to increase the availability of social welfare. In that sense, the quality of the software is directly related to address the users' needs and their level of satisfaction. To reflect user requirements to the software processes, the correct design of the database model provides a critical stage during software development. Database design is a fundamental tool for modeling all the requirements related to users' data. The possible faulty conditions in database design have adverse effects on all of the software development processes. The possible faulty conditions can also cause continuous changes in the software and the desired functionality of the targeted system which may result in user dissatisfaction. In this context, reflecting the user requirements accurately in the database model and understanding of the database model correctly by every person involved in the software development process is the factor that directly affects the success of software systems' development. In this study, a two-stage conceptual data modeling approach is proposed to reduce the level of complexity, to improve the understandability of database models and to improve the quality of the software. This study first describes the proposed two-stage conceptual data modeling. Than the proposed method's impact on software engineers' comprehension is also investigated and the results are compared with the degree of complexity of the related conceptual data models. Results of this study show that, the proposed two-stage conceptual modeling approach improves the understanding levels of software engineers and eliminated possible defects in this stage. © 2013 The Science and Information Organization.

    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.

    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.

    Exploring Software Process Variation Arising From Differences in Situational Context
    (Springer-verlag Berlin, 2017) Clarke, Paul M.; O'Connor, Rory V.; Solan, David; Elger, Peter; Yilmaz, Murat; Ennis, Adam; Treanor, Ryan; O’Connor, Rory V.
    The software development process is continuously changing, there is huge pressure to condense release cycles into shorter and shorter timeframes, tools are changing dramatically and companies must continually examine the efficacy of their development process. Attempting to hit a moving target is difficult and it is a decision which can have a major effect in terms of both the end-product and the business. In this paper, we discuss the role of situational context in deciding upon the software development process through the analysis of two case studies. The case studies take a detailed look at the organisational profile and context of each company in turn before we compare and contrast each situational context for factors that may influence the development process. We then compare the processes each company has chosen before our discussion of the role context plays in choosing a 'correct' software development process. While both companies have enjoyed sustained business growth and while both are agile in mindset, we find that they are in fact quite distinct in their processes, this distinction being driven by their different situational contexts.

    Software Developer's Journey a Story-Driven Approach To Support Software Practitioners
    (Springer-verlag Berlin, 2016) Atasoy, Berke; O'Connor, Rory V.; Martens, Jean-Bernard; Clarke, Paul; Yilmaz, Murat; O’Connor, Rory V.
    Agile development requires a highly iterative and collaborative design process, which relies on the successful interpretation of software development activities amongst team members throughout the overall process. However, contemporary methods and tools that support agile efforts provide little help in addressing context-specific tacit knowledge, which is difficult to externalize without a shared method of interpretation. Without a continuously updated interpretation of the project vision, it is difficult to claim a shared mental model, while this is actually vital for the success of an agile process. In this paper, we address this issue and seek guidance in an approach that is commonly used in film storycraft. Film production has ample experience with externalizing experiences with the help of visual planning tools and related techniques to orchestrate the creative efforts of vast interdisciplinary production teams. We therefore propose that methods and tools from visual storycrafting can be adapted to assist software developers, not only with externalizing and discussing context-specific tacit knowledge but also to keep them creatively engaged in the development process.

    Refactoring Software Development Process Terminology Through the Use of Ontology
    (Springer-verlag Berlin, 2016) Clarke, Paul M.; Mesquida Calafat, Antoni Lluis; Ekert, Damjan; Ekstrom, J. J.; Gornostaja, Tatjana; Jovanovic, Milos; Yilmaz, Murat; Calafat, Antoni Lluís Mesquida
    In work that is ongoing, the authors are examining the extent of software development process terminology drift. Initial findings suggest there is a degree of term confusion, with the mapping of concepts to terms lacking precision in some instances. Ontologies are concerned with identifying the concepts of relevance to a field of endeavour and mapping those concepts to terms such that term confusion is reduced. In this paper, we discuss how ontologies are developed. We also identify various sources of software process terminology. Our work to date indicates that the systematic development of a software development process ontology would be of benefit to the entire software development community. The development of such an ontology would in effect represent a systematic refactoring of the terminology and concepts produced over four decades of software process innovation.

    An Investigation of Software Development Process Terminology
    (Springer-verlag Berlin, 2016) Clarke, Paul; Mesquida, Antoni-Lluis; Ekert, Damjan; Ekstrom, J. J.; Gornostaja, Tatjana; Jovanovic, Milos; Yilmaz, Murat
    The practice of software development has evolved considerably in recent decades, with new programming technologies, the affordability of hardware, pervasive internet access and mobile computing all contributing to the emergence of new software development processes. The newer process initiatives, which include those which are sometimes referred to as agile or lean methods, have brought with them new terms, which sometimes reflect the introduction of novel concepts. Other times, new terms correspond to long established concepts that have been repackaged. The net position is that we have a proliferation of language and term usage in the software development process domain, a problem which has implications for assessors and assessment frameworks, and for the broader community. In this paper, we explore this problem, finding that it is worthy of further research. Plus, we identify a technique suited to addressing this concern: the establishment of a canonical software process ontological model.
