Established by an organization to achieve organizational goals
May take the form of command groups, task groups, and functional groups
Informal groups:
Formed naturally in response to common interests and shared values of individuals
Created for purposes other than the accomplishment of organizational goals
Do not have a specified time frame
Not appointed by the organization
Members can invite others to join from time to time
Command Groups - specified by the organizational chart and often composed of a leader and members who directly report to him/her
Interest Groups - usually continue over time and may last longer than general informal groups
Goals and objectives are specific to each group and may not be related to organizational goals and objectives
Task Groups - consist of people who work together to achieve a common task
Members are brought together to accomplish a narrow goal
Friendship Groups - formed by individuals who enjoy similar social activities, political beliefs, religious values, or common bonds
Members enjoy each other’s company and have a range of goals within a specified time
Functional Groups - created by an organization to accomplish specific goals within an unspecified time frame
Continue to function even after their goals have been achieved
Reference Groups - composed of people who are evaluated for social validation and social comparisons
Social validation allows individuals to justify their attitudes and values, while social comparison helps individuals evaluate their own actions by comparing themselves with others
