As the number of object-oriented software systems increases, it becomes more important for organizations to maintain those systems effectively. However, currently only a small number of maintainability prediction models are available for objectoriented systems. This paper presents a Bayesian network maintainability prediction model for an object-oriented software system. The model is constructe...

This paper proposes a number of metrics to assess the maintainability of code. Dominance relations are used to express the complexity of call relations and an assumption is made that when more complex relations are present within a source code module it is harder for an application to be maintained. The paper describes a case study whereby the changes in dominance relations are investigated ove...

Our study is focused on an evaluation of the maintainability characteristic in context long-term evolution open-source software. According to well established software quality models such as ISO 9126 and more recent 25010, remains among key characteristics alongside performance, security reliability. To achieve our objective, we selected three complex, widely used target applications for which ...

We performed an empirical study of the relation between technical quality of software products and the defect resolution performance of their maintainers. In particular, we tested the hypothesis that ratings for source code maintainability, as employed by the SIG quality model, are correlated with ratings for defect resolution speed. This study revealed that all but one of the metrics of the SI...
