    Software Change Size Measurement: an Exploratory Systematic Mapping Study
    (CEUR-WS, 2024) Hacaloglu, T.; Küçükateş Ömüral, N.; Kılınç Soylu, G.; Demirörs, O.
    Change in software projects can occur through various channels. Customers may request modifications or new features; appraisal activities such as reviews or testing may uncover issues that necessitate adjustments, or products may need to adapt to changes in their operating environment. Therefore, it is essential to assess these changes explicitly and objectively within the scope of software engineering activities. Specifically, quantifying change by measuring its size is crucial for successful management, as without a meaningful metric, it is impossible to accurately assess its impact on the project's effort, schedule, and cost. This study aims to explore the concept of change in software engineering literature, with a particular emphasis on the methods used to measure its size. The study reveals that the current literature on this topic is still in its early stages and the measurement and estimation of changes remain challenging throughout both development and maintenance phases. According to the reviewed articles, size is primarily used for effort estimation. Various software artifacts from different stages of the Software Development Life Cycle (SDLC) serve as input for change measurement, highlighting the need for a versatile size measurement applicable across all SDLC phases. Most of the reviewed articles interpret change in the context of maintenance activities. This research sets a benchmark for the status of software size measures for software change and highlights related problems to suggest further research topics. © 2024 Copyright for this paper by its authors.

    Challenges of using software size in agile software development: A systematic literature review
    (CEUR-WS, 2018) Hacaloglu,T.; Demirors,O.
    Software size is a fundamental measure for software management. Size is used for a variety of purposes, such as benchmarking, normalization, and portfolio measurement, and it is frequently considered as the sole input of estimation. Estimations can be produced for various reasons; e.g., to predict effort, cost and duration of software development projects. There are different types of software size measures. Particularly in projects where agile methodologies are adopted, measurement becomes a significant challenge as it is perceived as a non-value-added task and records of tasks such as requirements identification are not always consistent. The difficulties of applying traditional size measurement techniques in agile contexts, however, do not diminish the need, and new methods and techniques are introduced to improve the manageability of the agile projects. In this paper, we discuss estimation and measurement approaches in relation with ―software size in agile contexts. Based on this review, we present the perceptions of software size and related challenges, such as misinterpretation of size, difficulties in implementation, and acceptability of the measurement processes. We anticipate that providing a baseline for the state of software size measures in agile contexts and presenting related challenges, particularly in terms of its acceptability by practitioners can shed light on the development of new techniques. © 2018 CEUR-WS.

    Exploratory Review of Quantum Computing Software Requirements Specification and Their Measurement
    (CEUR-WS, 2024) Hacaloglu, T.; Soubra, H.; Bourque, P.
    Quantum software sets itself apart from classical software owing to its powerful computational abilities rooted in entanglement and superposition. Unlike classical software, quantum software diverges notably across various dimensions, including computational models, hardware architectures, algorithms, deployment platforms, and problem domains. Quantum software is also often not standalone and interacts heavily with classical software, stressing the importance of carefully considering hybridization. From a software engineering standpoint, researchers generally agree that a different approach is required for quantum software, and they advocate a Quantum Software Development Life Cycle (SDLC). This exploratory study briefly outlines the specifics of quantum software, overviews the proposed approaches regarding the software requirements of quantum software, and then reviews the current alternatives for measuring the functional size of quantum software. This study indicates that only a few papers in the literature discuss the requirements and functional size measurements of quantum software. Their results are also mostly conceptual and have not yet been empirically validated. Functional size measurement using quantum software remains an open area for further research. © 2024 Copyright for this paper by its authors.
