## Resource

Learn how to transform GitHub metadata into a bipartite graph to uncover hidden organizational dynamics. This discussion explores using network centrality and community detection to identify communication bottlenecks and improve team collaboration.

## Highlights
- Main idea: GitHub metadata (PRs, issues, discussions) can be modeled as a bipartite graph of people and projects to reveal team structure
- Practical takeaway: Use centrality measures like betweenness and eigenvector to identify subject matter experts and potential single points of failure
- Failure mode: Relying solely on quantitative metrics without qualitative context can lead to misinterpreting low connectivity as poor performance
- Practical takeaway: Implementing community detection algorithms helps identify natural clusters of collaborators within a larger engineering org
- Observation: Team centrality often drops when new members join, reflecting the natural period of learning and integration

## Topics

Network Analysis, GitHub, Graph Theory, Organizational Network Analysis, Python, Neo4j, Community Detection, Software Engineering Management, LLMs
