Which of the following is an ideal step that leaders can take to ensure that their teams build positive norms?

A) Increase the size of the team.
B) Increase team diversity.
C) Impose strict guidelines and penalties.
D) Strengthen team cohesiveness.
E) Encourage rivalry among members.

Strengthening team cohesiveness is an ideal step that leaders can take to ensure that their teams build positive norms. When team members feel connected and invested in each other's success, they are more likely to hold each other accountable for adhering to positive norms and supporting one another. This can lead to a culture of positivity and productivity within the team. Increasing the size of the team or encouraging rivalry among members can have the opposite effect and lead to negative norms or unhealthy competition. Imposing strict guidelines and penalties may be necessary in certain situations, but it should not be the primary strategy for building positive norms as it may create a culture of fear and resentment. Increasing team diversity can also be helpful, but it alone may not be sufficient to establish positive norms if team members do not feel a sense of unity and cohesion.
