The core idea
Teams can outperform individuals — more knowledge, more perspectives, more peer correction — but they can also underperform, when dominant members silence the right answer or conformity pressure produces bland consensus. The difference is process. Clarify the task, manage the conflict type, and pick a decision method that matches the trust level. — after Hackman

How to apply
Starting a new team.
- Establish norms on day one. Decision rule, cadence, how we handle disagreement.
- Assign clear roles. Facilitator, scribe, time-keeper. Reduces process conflict.
- Encourage task conflict. Actively ask for the dissenting view. Use structured protocols.
- Protect against groupthink. Write positions privately before speaking publicly.
