The performance advantages of teams over individuals are most evident in three situations: 1) when there is no clear "expert" for a particular task, 2) when the problems are complex and require a division of labor, and 3) when a riskier decision need be made.

Teams have the advantage in situations where a task requires a combination of expertise, complex problem-solving, and risky decision-making. In such situations, teams can pool resources, share knowledge, and provide different perspectives and insights, leading to better outcomes than an individual working alone. Additionally, teams can divide up labor and allocate resources more efficiently, leading to better use of time and resources. Therefore, the performance advantages of teams over individuals are most evident in these three situations.
