Characteristics of Groups/Teams• Is there a difference?
Group -- Team -- CrewCohesiveness
Interdependence

Costs of Groups• Definition of “Process loss”
– losses that occur due to being in a group– energy/time it takes to belong to a group
• “Groupthink”– "a mode of thinking that people engage in when
they are deeply involved in a cohesive group, when the members' strivings for unanimity override their motivation to realistically appraise alternative courses of action.” (Janis, 1982)

Characteristics of Groupthink – Highly cohesive group– Illusion of infallibilty– Stereotyping outsiders– Bounded rationality– Belief in inherent morality– Self-censorship– Direct pressure on dissenters– Mindguards

• Effect of design on behaviour– Informal or Formal discussion areas
– Individual work areas
– Privacy

• Crew Resource Management– Communication
– Interdependency
– Accountability
