The document discusses how to build effective teams. It identifies several roadblocks that can prevent teams from working effectively, such as mutual insincerity, unclear communication, personal interests that influence behavior, superstar complexes, and unresolved conflicts. It promotes a workshop called "Team in the Mirror" that aims to help teams communicate openly, build trust, clarify viewpoints, and work as a unified group through interactive exercises and coaching. The workshop costs 1,200 EUR for a one-day session plus follow up and claims to make teams more positive, effective and powerful by discovering their strengths and weaknesses.
