No team works in a vacuum. Some conditions may encourage collaboration, while others can act as constraints or inhibitors. This chapter examines “conditions,” the context or environment in which a team operates. Some conditions exhibit strong situational strength that greatly influence expected behaviors; others offer only hints or nudges about collaboration. Tangible elements such as organizational policies and practices (e.g., that guide compensation and promotion decisions), resources (e.g., are enough people assigned to the team, does the team have the information it needs), and less tangible elements such as senior leader support and organizational culture are all relevant for promoting teamwork. This chapter highlights six organizational practices and three senior leadership behaviors that can influence many teams, as well as four local team-specific conditions (i.e., resource availability, time availability, authority levels, and mission). The implications of working in a broader cultural context is also considered, as behavioral norms vary around the world.
