Fig. 2: Characterization of lead developers’ activity.
From: The dynamics of leadership and success in software development teams
a Distribution of the inter-commit times and cumulative distribution of the number of commits close in time (inset) for lead and non-lead developers. Lead developers exhibit higher frequency of commits and longer streaks of consecutive commits. b Distribution of the number of repositories in which lead and non-lead developers are active. Lead developers are involved in a larger number of repositories. Box plots indicate median (middle line), 25th, 75th percentile (box) and 5th and 95th percentile (whiskers) as well as outliers (single points). c Distribution of the repository switch time of lead and non-lead developers. Lead developers tend to switch from one project to another on a daily to weekly basis. d Number of downloads across repositories' lifetime stratified by lead developers' experience (median and its 95% confidence interval). Repositories led by experienced developers are downloaded more compared to those led by inexperienced ones. Time is binned into trimesters.
