From the data collected from 8 software development teams, 150 members in total in a branch of a global software development company in Thailand, the result suggested that teams with high-central leader in task-advice network had stronger team cohesion-performance effect than teams with low-central leader. The high-central leader in friendship network had less influence on team cohesion-performance effect.
