The Emergence and Collapse of Knowledge Boundaries

Area of Science:

• Organizational Behavior
• Knowledge Management
• Computational Social Science

Background:

• Knowledge transfer is crucial for engineering managers.
• Knowledge boundaries act as barriers to effective knowledge sharing within expert groups.
• Understanding the dynamics of these boundaries is essential for optimizing team performance.

Purpose of the Study:

• To investigate the formation and dissolution of knowledge boundaries in expert groups.
• To explore the role of task complexity and collective expertise in shaping communication patterns.
• To identify implications for organizations seeking to leverage collective knowledge.

Main Methods:

• Applied topic modeling, a natural language processing technique, to analyze communication transcripts.
• Utilized data from the U.S. Food and Drug Administration's Circulatory Systems Advisory Panel.
• Conducted qualitative exploration of relevant meeting data to support findings.

Main Results:

• Knowledge boundaries emerge as predicted when groups face increasingly difficult problems.
• Communication boundaries dissolve when collective expert ability is insufficient for task completion, particularly with high novelty.
• Collective expertise appears to be a key factor in knowledge boundary formation.

Conclusions:

• Knowledge boundaries are dynamic and influenced by both task challenge and group expertise.
• Under certain conditions, factors contributing to boundary formation may actually facilitate knowledge aggregation.
• Organizations must consider the level of collective knowledge when managing expertise and knowledge transfer.
