Software effort estimation is an important step for developing a software project, which has attracted many concerns of researchers [1], [2] ... In this paper, we propose an open source project based effort estimation method and provide a case study of GitHub. We not only employ the function point related measures as the cost metrics, but also ...

Conclusion and future work. In this paper, we propose an open source project based effort estimation method and provide a case study of GitHub. We not only employ the function point related measures as the cost metrics, but also take the personnel metrics into consideration for enriching the cost model.

The purpose of this qualitative multiple case study was to identify strategies that agile software development professionals use to provide project managers with accurate software development effort estimations. The study sample included software development professionals from five organizations who are responsible for producing

Use cases are often used as input for estimating software development effort. Several studies show that a particular estimation method based on use cases, the use case points method, performs well early in a project [3-5,7,17,19]. This method requires little technical insight and little effort. However, the studies reveal a need for more ...

Recent literature reviews aim to gather findings about: (i) a new view on best practices in model-based effort estimation ; (ii) a basis for the improvement of software estimation research ; (iii) a summary of estimation knowledge through a review of surveys on software effort estimation [P30]; and (iv) an extensive review of studies on the ...

Ayyldz et al. [6], performed a study on Desharnais dataset in order to find which attributes are influencing the performance of software effort estimation process. They have used the Pearson ...

This multi-case study aims to improve expert estimation of software development effort. Our goal is two-fold: 1) to propose a process to develop and evolve estimation checklists for agile teams, and 2) to evaluate the usefulness of the checklists in improving expert estimation processes.

2019. TLDR. This study assesses the quality of 13 datasets that have been used extensively in research on software effort estimation and proposes a template that could be used to both improve the ESE data collection/submission process and to evaluate other such datasets, contributing to enhanced awareness of data quality issues in the E SE ...

Software project management plays an important role in producing high-quality software, and effort estimation can be considered as a backbone for successful project management. Size is a very significant attribute of software by being the only input to perform early effort estimation. Even though functional size measurement methods showed successful results in effort estimation of traditional ...

Widely used estimation models show good results in estimating effort for software development projects where artifacts are built from scratch. The research is initially focused on the selection of an appropriate existing estimation model and then on its modification with new factors that would describe the reusability aspect. ... Case study was ...

In [5] the effort estimation is evaluated on the basis of genetic algorithm. There are so many approaches to estimate the effort like Machine learning approach, genetic algorithm, ANN, and algorithmic approaches [6, 7, 14]. In [11, 12] the authors have developed a tool to estimate the software risk and cost.

This paper provides a case study of a real aeronautical safety-critical software development project under the DO-178C process, where the COCOMO II method was applied as an estimation technique for the required software development effort. The main goal and contribution of the case study is to support the research on software effort estimation and provide software practitioners with useful ...

The results indicate that the guidance provided by the use case points method can support expert knowledge in the estimation process and support existing claims that use cases can be used successfully in estimating software development effort. Use case models are used in object-oriented analysis for capturing and describing the functional requirements of a system. Several methods for ...

This paper highlights a systematic review of studies associated with the best practices of use case point (UCP) and expert judgment-based software development effort estimation techniques.

Accurate estimations of software project effort is one of the most important tasks of software project development. The machine learning models have proven to provide high accuracy due to the learning natures of these techniques. Taking this into consideration, this paper aims at employing machine learning models of Random Forest (RF), Multilayer Perceptron (MLP) and Support Vector Machines ...

The results from this study support previous claims that the use case points method may support early estimation of software development effort. Necessary effort was estimated to 413 hours by the use case points method, and the minimum effort of the development teams was 431 hours.

In this way, the Effort Estimation Matrix serves as a bridge between theoretical, technical models and practical applications, enabling teams, leaders, and organizations to make more informed, context-driven decisions. Understanding the Matrix: At a high level, the Matrix helps teams categorize work based on understandability and predictability.

COCOMO (Constructive Cost Model) II is a parametric software development effort estimation model that requires size, personnel, product, and environmental attributes as input and returns the estimated effort in person-months (PM) as the output. This cost model is calibrated with 16 organizations' data.
