Overview
I took part as a speaker in ‘Wanted Con: People Analytics’, an online conference hosted by Wanted. The talks were pre-recorded in a studio on August 5, 2020. I gave a 30-minute talk titled 「리더십과 People Analytics: 분류모델과 사회연결망분석」 and then held a pair talk, ‘People Analytics 분석 방법론 뽀개기’, with manager 이중학. On the same day I also took part in a speakers’ discussion looking back on the conference.
Key points
- Limits of leadership typologies: I pointed out why so many leadership labels are created, and what traps the human tendency to find patterns even where there are none sets for typologies.
- Classification models: Instead of dividing types by intuition, I introduced classification models such as latent profile analysis (LPA) and latent class analysis (LCA), which distinguish groups from measured data.
- Leadership and social network analysis: I distinguished power that comes from the formal hierarchy from centrality identified in informal networks, and explained the relationships among structure, cognition, and power.
- Network structure and performance: Drawing on existing research, I summarized how the structure of relationships within an organization leads to social capital and performance.
- Pair talk: I answered practitioners’ questions about pre-processing text data, keyword networks and topic modeling, and the order in which to learn analysis methods. I emphasized that problem definition and domain knowledge come before methods.
