What factor distinguishes a group of people from a high-performance team?

A) nothing, they are the same
B) the social diversity of the group
C) the way members work with one another to achieve common goals
D) a fair bit of luck
E) the difficulty level of the tasks they are assigned

The way members work with one another to achieve common goals is the factor that distinguishes a high-performance team from a group of people. High-performance teams have a strong focus on collaboration, communication, and trust, which allows them to work together effectively towards a common objective. In contrast, a group of people may not share the same level of commitment or working style, leading to suboptimal performance. Social diversity and task difficulty are important factors that can affect team performance, but they alone do not make a high-performance team. Luck may also play a role, but it is not a reliable or sustainable factor for success.
