• Conference: ACM CHI Conference on Human Factors in Computing Systems, 2022
• Authors: Jerome Hergueux (CNRS, ETH Zürich), Samuel Kessler (University of Oxford)

Research Background and Issues

• Background:
  • Open source software, as a significant organizational innovation of the 20th century, brings together developers globally to collaborate on projects without relying on price signals or formal leadership.
  • The traditional view considers OSS as a "technical meritocracy," where "code is king," and leadership is primarily earned through high-quality code contributions.
  • Another perspective emphasizes the importance of communication skills in leadership, highlighting the role of inspirational leadership.
• Issues or Challenges:
  • Current research on leadership emergence in OSS is limited, particularly lacking comprehensive investigations into small teams.
  • There is a lack of systematic validation of the combined influence of technical and inspirational leadership in the process of leadership emergence.
• Motivation:
  • Address theoretical gaps in existing literature by exploring the distinct impacts of technical contributions and communication skills on leadership emergence.
  • Propose a quantitative analysis method to analyze comprehensive historical behavioral data of OSS developers.

Solution

• Research Methodology:

  • Utilize all developer interaction data on the GitHub platform from January 2010 to April 2017 (over 133 million records).
  • Introduce a survival analysis framework to dynamically observe developers' behaviors and the emergence of leadership roles over time.
  • Model and compare the impacts of technical contributions and inspirational communication separately.

• Key Variables:

  1. Technical Leadership:
     • Frequency and quality of code contributions (pull requests).
     • Number of issue reports and code reviews submitted.
  2. Inspirational Leadership (based on natural language processing analysis):
     • Use of future-oriented language (e.g., "will," "soon").
     • Team-affiliation language (e.g., "we," "us").
     • Use of emotional vocabulary, including positive and negative emotions, clarity, and uncertainty in language.
  3. Control Variables:
     • Team size, project popularity (GitHub stars), and developers' historical reputation.

• Statistical Methods:

  • Apply extended Cox proportional hazards models to analyze the probability of leadership emergence.
  • Standardize behavioral variables to facilitate cross-variable comparisons of regression coefficients.

Research Findings

• Key Results:
  • Both technical contributions and inspirational communication skills are significant predictors of leadership emergence.
  • In the technical dimension, the quantity and quality of submitted code significantly influence leadership emergence.
  • In the communication dimension, the use of future-oriented language, emotional expressions (including both positive and negative emotions), and team-affiliation language significantly increase the likelihood of developers becoming leaders.
  • Across multiple projects, leaders consistently exhibit distinct behavioral patterns from regular developers right from the start.
• Advantages and Innovations:
  • This study is the first to validate both technical meritocracy and inspirational leadership theories using large-scale data.
  • It overcomes previous research limitations that focused only on small samples or individual large projects, covering over 2 million developers and nearly 2 million projects.
• Insights from Experimental Results:
  • The probability of leadership emergence accumulates over time, but the pathways through which technical contributions and inspirational abilities exert their effects are complementary.
  • Larger team sizes are associated with lower proportions of later-stage leadership emergence, indicating more intense competition in large teams.
• Limitations and Future Directions:
  • The study does not directly explore whether leadership positively impacts team performance causally.
  • Future research could extend to other virtual collaboration or non-software teams for cross-domain comparative studies.
  • Platform designers could develop new tools based on the findings to enhance socialization and communication features.
