Relationship between Personality Traits and Software Quality - Big Five Model vs. Object-oriented Software Metrics
Proceedings of the 19th International Conference on Enterprise Information Systems
The activity of analyzing personality of software developers has been a topic discussed by many researchers over the past few years. However, their relation to software metrics has hardly been mentioned in the literature. This work aims to identify the influence of human personality on quality of software products. At first, a psychological test was performed using the Big Five model for a set of developers working in industry and, subsequently, object-oriented software metrics were applied to
... ndividual software developed by members of the same group. As a result, it was evidenced, through statistical analysis, that the factors Consciousness, Neuroticism and Openness to Experience have a significant relationship with the Cyclomatic Complexity metric. In addition, factors Extroversion, Agreeableness and Neuroticism have significant relation with metric Coupling between Objects. In another analysis, taking into account ideal average values for each software metric, it was evidenced that Extroversion and Neuroticism factors have a significant relationship with metric Depth of Inheritance Tree. Extroversion and neuroticism were the only factors that obtained a significant relation with software metrics in the two proposed analyzes. Therefore, additional studies are needed to determine any deeper connection between personality and software quality.
