Do open source software projects provide and maintain tests? What metrics are correlated with the test success? This paper answers these questions by executing tests of 452 open source software projects in GitHub and measuring 13 metrics from 77 projects. Only 117 projects passed all test cases. Additionally, the results are correlated with the comment density, public documented API density, an...

Compared with software projects, the estimation of website projects is not mature enough without any methods for size or workload estimation. This paper researched Function Point Analysis (FPA), the most important size estimation method in software projects and then constructed Commerce Website Function Point Analysis (CWFPA) by introducing principles of FPA into commerce website projects. The ...

The world of software has demonstrated the remarkable appeal of communal software development. Large number of software projects can leverage, reuse, and coordinate their work through internet and web-based technology. For example, Source-Forge currently hosts about sixty thousand software systems, similar strategies have suggested for corporate software development. With thousands of projects,...

Although appropriate sizing of software projects is a concern in software development, Information Systems managers generally do not consider maintenance project size as a potentid influence on software maintenance productivity. This view ignores potential efficiency gains which may arise from proactive renovation strategies such as batching similar maintenance requests into larger projects. In...

In this paper, the essential characteristics of software development projects in the open source environment are described. This model of freely distributed, highly decentralized, democratic software development with little management hierarchy, overhead, or salary compensation has made a revolution in the software industry. These open source projects, like typical commercial software projects,...

This study examines temporal patterns of software systems defects using the Autoregressive Integrated Moving Average (ARIMA) approach. Defect reports from ten software application projects are analyzed; five of these projects are open source and five are closed source from two software vendors. Across all sampled projects, the ARIMA time series modeling technique provides accurate estimates of ...

Accurate estimating is one of the most important activities in the field of software project management. Different aspects of software projects must be estimated among which time and effort are of significant importance to efficient project planning. Due to complexity of software projects and lack of information at the early stages of project, reliable effort estimation is a challenging issue. ...

A reliable and accurate similarity measurement between two software projects has always been a challenge for analogy-based software cost estimation. Since the effort for a new project is retrieved from similar historical projects, it is essentially to use the appropriate similarity measure that finds those close projects which in turn increases the estimation accuracy. In software engineering l...

The reasons for measuring software productivity are to identify how to reduce software development costs, improve software quality, and improve the rate at which software is developed. In this paper, a data set of 572 software individual projects developed from 2005 to 2010 with practices based on a process specifically designed to laboratory learning environments (Personal Software Process) is...

Software effort estimation is an important process of system development life cycle, as it may affect the success of software projects if project designers estimate the projects inaccurately. In the past of few decades, various effort prediction models have been proposed by academicians and practitioners. Traditional estimation techniques include Lines of Codes (LOC), Function Point Analysis (F...
