Links between the personalities, styles and performance in computer programming

There are repetitive patterns in strategies of manipulating source code. For example, modifying source code before acquiring knowledge of how a code works is a depth-first style and reading and understanding before modifying source code is a breadth-first style. To the extent we know there is no study on the influence of personality on them. The objective of this study is to understand the influence of personality on programming styles. We did a correlational study with 65 programmers at the University of Stuttgart. Academic achievement, programming experience, attitude towards programming and five personality factors were measured via self-assessed survey. The programming styles were asked in the survey or mined from the software repositories. Performance in programming was composed of bug-proneness of programmers which was mined from software repositories, the grades they got in a software project course and their estimate of their own programming ability. We did statistical analysis and found that Openness to Experience has a positive association with breadth-first style and Conscientiousness has a positive association with depth-first style. We also found that in addition to having more programming experience and better academic achievement, the styles of working depth-first and saving coarse-grained revisions improve performance in programming.Comment: 27 pages, 6 figure

Are team personality and climate related to satisfaction and software quality? Aggregating results from a twice replicated experiment

This is the author’s version of a work that was accepted for publication in Information and Software Technology. Changes resulting from the publishing process, such as peer review, editing, corrections, structural formatting, and other quality control mechanisms may not be reflected in this document. Changes may have been made to this work since it was submitted for publication. A definitive version was subsequently published in Information and Software Technology, [VOL 57, (2015)] DOI 10.1016/j.infsof.2014.09.002Context Research into software engineering teams focuses on human and social team factors. Social psychology deals with the study of team formation and has found that personality factors and group processes such as team climate are related to team effectiveness. However, there are only a handful of empirical studies dealing with personality and team climate and their relationship to software development team effectiveness. Objective We present aggregate results of a twice replicated quasi-experiment that evaluates the relationships between personality, team climate, product quality and satisfaction in software development teams. Method Our experimental study measures the personalities of team members based on the Big Five personality traits (openness, conscientiousness, extraversion, agreeableness, neuroticism) and team climate factors (participative safety, support for innovation, team vision and task orientation) preferences and perceptions. We aggregate the results of the three studies through a meta-analysis of correlations. The study was conducted with students. Results The aggregation of results from the baseline experiment and two replications corroborates the following findings. There is a positive relationship between all four climate factors and satisfaction in software development teams. Teams whose members score highest for the agreeableness personality factor have the highest satisfaction levels. The results unveil a significant positive correlation between the extraversion personality factor and software product quality. High participative safety and task orientation climate perceptions are significantly related to quality. Conclusions First, more efficient software development teams can be formed heeding personality factors like agreeableness and extraversion. Second, the team climate generated in software development teams should be monitored for team member satisfaction. Finally, aspects like people feeling safe giving their opinions or encouraging team members to work hard at their job can have an impact on software quality. Software project managers can take advantage of these factors to promote developer satisfaction and improve the resulting product.This research has been funded by the following projects: Experiment Replication and Synthesis Technologies in SE (MICINN TIN2011-23216) and Go Lite (MICINN TIN2011-24139)

Investigating the effects of personality traits on pair programming in a higher education setting through a family of experiments

Evidence from our systematic literature review revealed numerous inconsistencies in findings from the Pair Programming (PP) literature regarding the effects of personality on PP’s effectiveness as a pedagogical tool. In particular: i) the effect of differing personality traits of pairs on the successful implementation of pair-programming (PP) within a higher education setting is still unclear, and ii) the personality instrument most often used had been Myers-Briggs Type Indicator (MBTI), despite being an indicator criticized by personality psychologists as unreliable in measuring an individual’s personality traits. These issues motivated the research described in this paper. We conducted a series of five formal experiments (one of which was a replicated experiment), between 2009 and 2010, at the University of Auckland, to investigate the effects of personality composition on PP’s effectiveness. Each experiment looked at a particular personality trait of the Five-Factor personality framework. This framework comprises five broad traits (Openness to experience, Conscientiousness, Extraversion, Agreeableness, and Neuroticism), and our experiments focused on three of these - Conscientiousness, Neuroticism, and Openness. A total of 594 undergraduate students participated as subjects. Overall, our findings for all five experiments, including the replication, showed that Conscientiousness and Neuroticism did not present a statistically significant effect upon paired students’ academic performance. However, Openness played a significant role in differentiating paired students’ academic performance. Participants’ survey results also indicated that PP not only caused an increase in satisfaction and confidence levels but also brought enjoyment to the tutorial classes and enhanced students’ motivation

Perserverance measures and attainment in first year computing science students.

We investigate the link between concepts of perseverance such as conscientiousness and grit, and the academic attainment of first year computing students. We review the role that perseverance plays in learning models, as well as describing the trait of conscientiousness in the Five Factor Model of personality. We outline research that links this trait with academic success, before focussing on more recent, narrower conceptualisations of perseverance such as academic tenacity and grit. We describe one of the questionnaire tools that have been used to assess the construct of grit. We give details of an investigation that looked for correlations between student responses to Duckworth's Grit Survey, the Big Five Inventory (BFI) Personality Survey and summative attainment scores in a first year programming course. The results suggest a weak but significant correlation between conscientiousness, grit and programming achievement. We discuss these results as well as the limitations of the method used. Finally, we make some observations about the importance of these concepts in Computer Science education and outline further work in this area

Toward an Understanding of Preference for Agile Software Development Methods from a Personality Theory Perspective

This paper presents the results of an exploratory research study that investigates factors contributing to preference for the agile software development approaches. The initial exploration revolves around the Five Factor Model of personality and the premise that these personality factors provide a partial explanation of preference for an agile approach. A survey instrument for measuring the preference for agile methods was developed and validated. The results from the quantitative data collected from the survey study indicate that three out of the five personality factors from the Five Factor Model show a correlation with above average preference for agile methods. These factors are extra version, openness and neuroticism. The first two have a positive relationship with agile preference while neuroticism (emotional instability) has a negative relationship with agile methodology preference. To further investigate the results, an exploratory factor analysis was performed on the data, which identified three factors that may also contribute to a preference for agile methods

Personality Traits of Scrum Roles in Agile Software Development Teams - A Qualitative Analysis

Software development teams must be able to react rapidly to changing customer requirements. Therefore, agile software development methodologies have evolved in the last decades. Interpersonal and social skills, which are influenced by personality traits, are of fundamental importance for a successful agile software development. While the significance of the human factor is widely acknowledged, scant studies investigate the impact of personality factors on software development success and those few studies report contradictory results. Hence, we conducted interviews with eleven Scrum team members from seven different companies to investigate which personal characteristics are important for agile software development success. We use the five-factor model as a theoretical basis for our investigation, more specifically, we have applied the facets developed by Costa and McCrae. This more detailed approach enables us to give an explanation of the conflicting outcomes of prior investigations. Our study contributes to existing research by suggesting that the most important facets for single Developers are altruism, compliance, tender-mindedness, dutifulness and openness to values. The Scrum Master needs tender-mindedness, assertiveness, dutifulness, achievement striving and stability. In contrast, straightforwardness, compliance, modesty, order and assertiveness are important for the Product Owner
