I don’t understand this Management question and need help to study.

In the Discussion Forum type a 600-word (minimum) paper about Unit 9 (Page 136 to page 153). What is your understanding of the material covered? Also address in your own words:

• Show how role requirements change in different situations.
• Demonstrate how norms exert influence on an individual’s behavior.
• Describe how issues of cohesiveness and diversity can be integrated for group effectiveness.
• Contrast the strengths and weaknesses of group decision making.
