    Master Thesis
    Bilgi ve İletişim Teknolojileri ile Ters Tedarik Zinciri Yönetimi Geliştirilmesi
    (2015) Germiyanoğlu, Sercan Noyan; Koyuncu, Murat
    A SCM system having RSCM capabilities is modeled giving special focus on the usage of ICT. Three different RSCM processes (Customer Return, Out-of-product Return and Repair and Non-Repair Situation Return) are modeled separately using sequence diagram of UML and ICT usage is analyzed in each one to improve the process. These modeled processes are compared with the RSCM model of a company to determine its applicability in real life. The aim of the study is to show how the RSCM processes can be improved by efficient usage of ICT. Companies that can achieve this can gain competitive advantages over their competitors. This study is important to alleviate the lack of studies in this field and may help to companies having intension to improve their RSCM.

    Stakeholder Theory and Applications in Information Systems
    (Springer, 2010) Mishra, Alok; Dwivedi, Yogesh K.
    Stakeholder theory is widely used in management in examining organizational environment, strategic management, ethical issues, business planning process, e-government, project management, environment management, etc. Recently stakeholders are also seen as a means to more successful information and communication technologies and information system development and implementation issues. In this chapter, stakeholder theory, its origin and applications in Information Systems field in literature are discussed.

    Does Domain-Driven Design Lead To Finding the Optimal Modularity of a Microservice?
    (Ieee-inst Electrical Electronics Engineers inc, 2021) Vural, Hulya; Koyuncu, Murat
    Information systems are moving into the cloud. The new requirements enforced by cloud standards are high availability, high scalability, and a reduced mean time to recovery. Due to these new requirements, information system architecture styles are also evolving. Microservice architecture is becoming the de facto standard for developing highly modular cloud information systems. Since microservices were introduced, there has been an ongoing debate concerning how to choose the granularity of a microservice. In this study, the optimal point of granularity for microservices is examined based on coupling and cohesion values. The present study is based on two design examples generated in previous studies that applied domain-driven design in proposing microservices. Both examples are modified to generate more and less granular microservices. The coupling and cohesion values of the original examples are compared to those of the more and less granular microservices. We observe that domain-driven design has delivered a good end result for finding modular microservices.
