Item Blockchain-based decision support system for measuring environmental and social sustainability in the supply chain(Thesis (M.A.) - Bogazici University. Institute for Graduate Studies in the Social Sciences, 2022., 2022.) Okay, Can Nilüfer.; Sencer, Aslı.Globalization has caused supply chains to become more complex and has created problems of misinformation, lack of transparency, traceability, and control. There is an inappropriate use of natural resources and exploitation of people and the environment at lower-tier levels of opaque value chains. Companies are pressured to be held accountable for these malpractices at the lower-tier levels of their suppliers. Consumers and governments demand that organizations reveal the environmental and social impacts of their supply chain activities. It is expected from companies to transform their business models to prioritize transparency and the environmental and social sustainability of their operations. Blockchain technology offers the essential properties that can make this transformation possible, it enables transparency, traceability, security, and real-time information sharing across supply chain participants. It has the potential to overcome the challenges in sustainable supply chain management. In this thesis, a quantitative sustainability measurement model for the environmental and social sustainability of supply chains is presented. Subsequently, a blockchain-based decision support system is developed to track and trace products throughout the supply chain and assess the environmental and social sustainability of the products and supply chain actors. Companies can use this system to gain more information about their supply chain activities and measure their sustainability performance.Item Challenges in service catalog management and recommendations for higher success(Thesis (M.A.) - Bogazici University. Institute for Graduate Studies in Social Sciences, 2022., 2022.) Bal, Efsun.; Sencer, Aslı.The service catalog is a priceless resource, providing a single point of access to all of the services that the company provides to external and internal clients through IT and other departments. It delivers several benefits when it works effectively and is structured holistically, including clarity in pricing the services given, cost reduction, operational efficiency, successful service level management, and increased customer satisfaction. Furthermore, because it is linked to so many other processes, unsuccessful applications here have a detrimental impact on many other operations. Despite all its criticality and usefulness, many companies fail to build the service catalog structure successfully. This research aims to identify the challenges companies face while trying to implement and manage service catalogs and, based on their criticality, share some recommendations for better adoption. The stages of service catalog process implementation are grouped under four categories for service identification, service catalog implementation, maintenance, and adoption. Based on the data collected from 98 respondents, the critical challenges in providing higher success in IT service catalog management are identified and recommendations are given for higher success. Accordingly, keeping service catalog up-to-date, identifying the services and service relations, and creating ownership and adoption have been identified as the top three most important challenges for successful service catalog management. Companies that have strategic plan, assign service catalog manager and implement best practices have higher success in SCM.Item Cyber insurance adoption in SMEs as a risk management tool in digitalization(Thesis (M.A.) - Bogazici University. Institute for Graduate Studies in Social Sciences, 2022., 2022.) Özkeleş Yıldırım, Aslı.; Metin, Bilgin.; Taşkın, Nazım.Small – medium sized enterprises (SMEs) create the backbone of the Turkish economy. Digitalization is a key advancement for SMEs in order to create efficiency and open up new opportunities for innovation. However, digitalization makes SMEs vulnerable to cyber threats by opening an outlet to other systems. The lack of awareness of cyber protection and the increasing advancements in cyberattacks puts SMEs at risk of data breaches which in turn causes damage to the company. Cyber insurance is considered a risk management tool for the coverage of costs in the event of an unexpected cyber incident. Even though the coverages are beneficial for the insured, the cyber insurance market is far from reaching its full potential. The study aims to find the factors of cyber insurance adoption for SMEs and the effects of cyber insurance on digitalization through cyber readiness, organizational security performance and information and communication technologies (ICT) adoption. The model created for the study was based on technology-organization-environment (TOE) context extended with individual context and the post adoption effects of cyber insurance. A quantitative survey aimed towards SMEs was conducted to test the model. Methods for increasing adoption of cyber insurance among SMEs were suggested based on the model outcomes.
