Conference Object Citation - Scopus: 1A Survey on Cosmic Students Estimation Challenge(CEUR-WS, 2022) Hacaloğlu, Tuna; Say, Bilge; Ünlü, Hüseyin; Küçükateş Ömüral, Neslihan; Demirörs, OnurSoftware 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.Conference Object A Size Measurement Method for Enterprise Applications(CEUR-WS, 2022) Küçükateş Ömüral, Neslihan; Demirörs, OnurEnterprise 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.Conference Object Citation - Scopus: 3Exploring Reuse Levels in Erp Projects in Search of an Effort Estimation Approach(Institute of Electrical and Electronics Engineers, 2018) Demirörs, Onur; Küçükateş Ömüral, NeslihanEnterprise Resource Planning (ERP) projects have special characteristics that differentiate them from other kinds of software projects. Main difference that affects effort estimation results is high reuse rates of ERP projects. This paper presents our exploratory work to establish an approach to calculate reuse reflective size of ERP projects, which could be a primary input for effort estimation. We explored the usability of COSMIC function points as the base unit and its convertibility to reuse reflective size using reuse levels. We have performed a case study on an SAP Implementation project. We were able to calculate COSMIC size and reuse levels using the documents available for the project. We discuss the results as well as challenges and opportunities in the light of the case study.Conference Object Citation - Scopus: 5Effort Estimation Methods for Erp Projects Based on Function Points: a Case Study(Association for Computing Machinery (ACM), 2017) Küçükateş Ömüral, Neslihan; Demirörs, OnurEnterprise Resource Planning (ERP) Systems evolve at a rapid pace based on customer and industry expectations. As a result, historic project data for these kinds of projects lose their value especially for analogy based estimation methods. In this rapidly evolving domain, function point based methods might provide a sound alternative for ERP effort estimation. This paper presents the results obtained by applying three methods published in the literature in which function points are used as an input for ERP effort estimation. The evaluation of these methods with respect to their measurement processes and estimation errors are presented; their advantages and disadvantages are discussed.
