『Good Team, Bad Team』に関するよくある質問

What is Good Team, Bad Team by Sarah Thurber and Blair Miller about?

Good Team, Bad Team provides a leadership toolkit grounded in cognitive diversity and problem-solving science. It introduces the FourSight System—a framework based on 6+ million data points—to help leaders manage team dynamics, resolve conflicts, and drive collaboration. The book contrasts how good teams (focused on challenges) and bad teams (stuck in infighting) operate, offering actionable strategies to align diverse thinkers.

Who should read Good Team, Bad Team?

This book is ideal for leaders, managers, and HR professionals seeking science-backed methods to improve team performance. It’s particularly valuable for those navigating cognitive diversity in fast-paced industries like tech, healthcare, or education. Entrepreneurs and team facilitators will also benefit from its practical exercises and case studies from organizations like NASA and Nike.

Is Good Team, Bad Team worth reading?

Yes—the book combines rigorous research with relatable examples, making it a standout in leadership literature. Its focus on the FourSight System and cognitive diversity offers fresh insights beyond typical team-building advice. Readers praise its actionable tools, such as problem-solving style assessments, to diagnose and fix team inefficiencies.

What is the FourSight System in Good Team, Bad Team?

The FourSight System identifies four problem-solving stages: Clarify (defining the problem), Ideate (generating solutions), Develop (refining ideas), and Implement (executing plans). Teams often stall when members prioritize different stages. The book provides strategies to align these preferences, helping leaders harness cognitive diversity for better outcomes—a framework validated by NASA, Nike, and the U.S. Navy SEALs.

How does Good Team, Bad Team address cognitive diversity?

Cognitive diversity refers to how individuals approach problems differently. Thurber and Miller explain that unmanaged diversity causes conflict, but structured through FourSight, it fuels innovation. The book teaches leaders to identify team members’ problem-solving styles (e.g., clarifiers vs. implementers) and create workflows that leverage these differences.

What real-world examples does Good Team, Bad Team use?

The authors cite Disney’s cross-departmental collaboration, Nike’s product innovation teams, and NASA’s crisis-response protocols. These cases show how aligning problem-solving styles prevents miscommunication and accelerates results. For example, NASA teams used FourSight to balance rapid ideation with meticulous risk assessment during missions.

How does Good Team, Bad Team help resolve team conflicts?

The book advises leaders to diagnose conflicting problem-solving styles (e.g., an ideator clashing with a developer) and refocus the team on shared goals. Tactics include structured brainstorming sessions, role clarity exercises, and “energy mapping” to redirect frustration toward challenges, not colleagues.
