    Size Measurement and Effort Estimation in Microservicebased Projects: Results From Pakistan
    (CEUR-WS, 2023) Soylu, Görkem Kılınç; Ünlü, Hüseyin; Ahmad, Isra Shafique; Demirörs, Onur
    During the last decade, microservice-based software architecture has been a common design paradigm in the industry and has been successfully utilized by organizations. Microservice-based software architecture, specifically in the form of reactive systems, has substantial differences from the more conventional design paradigms, such as the object-oriented paradigm. The architecture moved away from being data-driven and evolved into a behavior-oriented structure. The usage of a single database is replaced by the structures in which each microservice is developed independently and has its own database. Therefore, adaptation demands software organizations to transform their culture. In this study, we aimed to get an insight into how Pakistani software organizations perform size measurement and effort estimation in their software projects which embrace the microservice-based software architecture paradigm. For this purpose, we surveyed 49 Pakistani participants from different agile organizations over different roles and domains to collect information on their experience in microservice-based projects. Our results reveal that although Pakistani organizations face challenges, they continue using familiar subjective size measurement and effort estimation approaches that they have used for traditional architectures. © 2023 Copyright for this paper by its authors.

    A Survey on Cosmic Students Estimation Challenge
    (CEUR-WS, 2022) Hacaloğlu, Tuna; Say, Bilge; Ünlü, Hüseyin; Küçükateş Ömüral, Neslihan; Demirörs, Onur
    Software project management is a significant software engineering practice that is highly related to achieving software-specific project goals. This study aims to share students’ perceptions of incorporating an international software estimation challenge called “COSMIC Students’ Estimation Challenge” into a software project management course. For this aim, students were taught the COSMIC Functional Size Measurement method and entered the competition. After the competition, a questionnaire asking for the students’ opinions was collected. The objective of the research is to get an insight into to what extent incorporating this type of competition activity -a challenge- can contribute to students’ learning perceptions. In the long run, the findings can contribute to creating a foresight about making the necessary curriculum arrangements to form a more up-to-date and dynamic education plan by including the methods applied in the software industry in Software Engineering education. The results suggest that this kind of competition experience and preparation is helpful for students to learn the COSMIC method.

    A Size Measurement Method for Enterprise Applications
    (CEUR-WS, 2022) Küçükateş Ömüral, Neslihan; Demirörs, Onur
    Enterprise Applications are known as one of the best practices of software reuse. They are complex applications, including most of the business processes. In this domain, size measurements and effort predictions are mostly performed in an ad-hoc fashion, and they frequently suffer from schedule and budget overruns. We developed a size measurement method for Enterprise Applications and explained this novel method in this paper. We categorized transactions as “unchanged”, “changed”, and “new” in this method. We defined a size measurement unit, Data Transaction Point (DTP), and measured size as DTP in these categories. We conducted a sample size measurement with a well-known business process to demonstrate the implementation of the method.

    Sayısal Devrelerin Model Kontrol Tabanlı Testi
    (CEUR-WS, 2015) Takan, Savaş
    Bu tezin amacı yazılım mühendisliği alanında yaygınca kullanılan bir test yöntemi olan model doğrulama tabanlı test yönteminin, devrelerin gecikme hata testinin denetlenmesi işlemine uygulamaktır. Devre gecikme hatası devrelerin istenilen zamanda istenilen işlevin yerine getirilmemesinden kaynaklanmaktadır. Bu metodolojide, öncelikle devre bir zamanlı otomata olarak modellenir ve böylece devrenin zamansal karakteristikleri ortaya çıkarılır. Ardından model sürekli olarak belirli varsayımlar çerçevesinde gecikme hataları oluşması için mutasyona uğratılır ve tüm mutant modeller verilen niteliklere göre model doğrulayıcı tarafından kontrol edilir. Test giriş dizisi, model doğrulayıcı tarafından geri döndürülen karşıt örneklerden oluşur. Aşağıda metodolojinin kısa özeti verilmiştir.
