Final answer:
The team development stage where team members coordinate and share rules of conduct is known as the norming stage. For the secondary question about group values and norms influencing individual behavior, the answer is c. Reference group.Thus the correct option is b.
Step-by-step explanation:
The team development stage in which members of the team begin to better coordinate their efforts as a unit with shared rules of conduct is the norming stage. During this phase, the team establishes its values, norms, and beliefs that come to serve as the standard for the members' behavior. This creates a sense of unity and increases the overall efficacy and performance of the team. To put this into context, think of the norming stage as the moment when a sports team has gotten to know each other and starts to work together seamlessly, with each player understanding their role and following the agreed-upon strategies and rules.
Similarly, the answer to the secondary question you asked about group values and norms is c. Reference group. A reference group is a type of group that individuals use as a standard for evaluating their own behavior. This group's expectations and standards form the benchmark against which individuals measure their conduct.
