Conference Object Citation - WoS: 7Citation - Scopus: 12Utilization of Three Software Size Measures for Effort Estimation in Agile World: a Case Study(IEEE, 2022) Unlu, Huseyin; Hacaloglu, Tuna; Buber, Fatma; Berrak, Kivilcim; Leblebici, Onur; Demirors, OnurFunctional size measurement (FSM) methods, by being systematic and repeatable, are beneficial in the early phases of the software life cycle for core project management activities such as effort, cost, and schedule estimation. However, in agile projects, requirements are kept minimal in the early phases and are detailed over time as the project progresses. This situation makes it challenging to identify measurement components of FSM methods from requirements in the early phases, hence complicates applying FSM in agile projects. In addition, the existing FSM methods are not fully compatible with today's architectural styles, which are evolving into event-driven decentralized structures. In this study, we present the results of a case study to compare the effectiveness of different size measures: functional -COSMIC Function Points (CFP)-, event-based - Event Points-, and code length-based - Line of Code (LOC)- on projects that were developed with agile methods and utilized a microservice- based architecture. For this purpose, we measured the size of the project and created effort estimation models based on three methods. It is found that the event-based method estimated effort with better accuracy than the CFP and LOC-based methods.Conference Object Citation - WoS: 6Citation - Scopus: 6Mikroservis Mimarisinde Analiz ve Tasarım: Türkiye’den Bir İnceleme(IEEE, 2020) Bilgin, Burak; Ünlü, Hüseyin; Demirörs, OnurThe demand for more flexible, responsive and reliable software applications and the availability of internet infrastructure to respond to this demand, led to a new generation of cloud-based web applications. As a result, cloud- based distributed web applications working together in a microservice-based architecture has gained popularity. The concept of microservice-based architecture is quite new and software organizations need to transform their culture to develop applications in this fashion. However, there is a lack of research studies in the literature that explores the common practices for the analysis and design of microservices. Thus, we performed a survey to explore the organizational choices on software analysis and design when working with microservices. In this paper, we present the results from Turkey. The results provide a snapshot of the software industry that utilizes microservices and suggests a set of challenges researchers can focus on in the area. © 2020 IEEE.
