The document discusses the definition of groups and key characteristics of groups according to Adler and Rodman. Some key points include:
- A group is defined as a small collection of 3+ people who interact face to face over time to achieve common goals and who are interdependent.
- Groups have norms or shared expectations that govern members' behaviors and procedures. Norms can be either formal/explicit rules or implicit/implied norms.
- Within groups, members take on various roles both formally assigned and informal that help the group function effectively through task accomplishment and social relationships or can be dysfunctional if they prevent group work.
