1 Group Dynamics

2

3 Groups Two or more individuals, interacting and interdependent, who have come together to achieve particular objectives. A group can be defined as a small group of people with complementary skills and abilities who are committed to a leader's goal and approach and are willing to be held accountable by the leader

4 Groups  Formal A designated work group defined by the organization's structure. Designated work assignments. Directed towards organizational goals  Informal A group that is neither formally nor informally structured nor organizationally determined ; appears in response to the need of social interactions. Friendship groups; kitty groups

5 Need to join Groups  Security.  Status.  Self Esteem  Affiliation  Power  Goal Achievement

6 Pivotal Studies in the Origins of Group Dynamics  Sherif (1936) investigated social norms among groups of people one of the first studies that studied group phenomena experimentally  Newcomb (1939) topic similar to Sherif used naturalistic observation showed that attitudes of individuals are strongly related to the groups to which they belong

7 Pivotal studies, cont.  Whyte (1937) study of social clubs, political organizations, and racketeering use of participant observer technique Contributions (Whyte, 1937)  dramatized the great significance of groups in the lives of individuals  gave impetus to the interpretation of group properties and processes in terms of interactions  generated new hypothesis concerning intra group relations

8 Pivotal studies, cont.  Lewin, Lippitt, and White (1939) studied influences of leadership style on group and its members found that individual members were transferred from one group to another their aggressiveness change to approach the new group level Earliest use of the phrase “group dynamics”

9 Work Groups vs. Work Teams  Work group -- collection of two or more people who interact with one another and share some interrelated task goals  Work team -- a work group with 3 specific properties: actions of individuals must be interdependent and coordinated each member must have a particular, specified role. there must be common task goals and objectives.

11 Types of Groups / Teams  Command Group- composed of individuals who directly report to a given manager.  Task Group- Individuals working together to complete a task.  Self Managed-Individuals who operate without a manager and responsible for complete work process/ segment

12 Autonomous Work Groups  Alternative organizational structuring where an entire product (or service) is produced (or provided) by a small group of employees  Properties differ by setting  Job satisfaction higher than in traditional structures  Job performance equal to traditional in manufacturing organizations higher than traditional in non-manufactoring organizations

13 Types of Groups/Teams  Virtual teams- Teams that use computer technology to link physically dispersed members in order to achieve a common goal.  Cross Functional teams – Hybrid grouping of individuals who are experts in various specialties and who work together on a specified task.

14 Types of Groups/Teams  Problem solving teams – Employees form the same department and functional areas who are involved in efforts to improve work activities or solve specific problems.

15 Quality Circles  Groups of employees who meet periodically to discuss problems and propose solutions relevant to their jobs  Benefits (in theory) individuals enjoy greater participation welcome break from routine better production procedures  Problem: Usually considered a parallel function; have no enforcing power.

16 Properties of Groups  Roles -- can be formal or informal  Norms -- unwritten rules of behavior  Group cohesiveness -- sum of forces keeping the group together  Process loss -- time and effort expended on activities not directly related to task accomplishment

17 Role Structures  Roles Parts individuals play in groups in helping the group reach its goals.  Role Structure Set of defined roles and interrelationships among roles group members define and accept.  Role Ambiguity When the sent role is unclear.  Role Overload When role expectations exceed an individual’s capacities.

18 Characteristics of Groups and Teams  The Development of a Role The first two stages of role development are group processes as the group members let the individuals know what is expected of them. The other two parts are individual processes as the new group members perceive and enact their roles. Expected role Sent role Perceived role Enacted role

19 Role Structures Role Conflict Inter-role Conflict: Conflict between roles. Intra-role Conflict: Conflicting demands from different sources. Intra-sender Conflict: When a single source sends contradictory messages. Person-role Conflict: Discrepancy between role requirements and an individual’s values, attitudes, and needs.

20 Behavioral Norms  Norms Standards of behavior that a group accepts and expects of its members.  Factors contributing to norm conformity: Peer pressure Stimulus prompting group behavior Individual traits Situational factors  Socialization Norm conformity that occurs when a person goes from outsider to insider.

21 Group Cohesiveness Factors increasing cohesiveness  Inter-group competition  Personal attraction  Favorable evaluation  Agreement on goals  Interaction Factors reducing cohesiveness  Group size  Disagreement on goals  Intra-group competition  Domination  Unpleasant experiences

23 Group Polarization Tendency for people to exaggerate preexisting attitudes as a result of group discussion. They move to more extreme shared attitudes.

24 Group Polarization  Are groups more conservative or riskier decision makers than individuals?  Group Polarization -- the groups decision tends to be more extreme than the mean of its individuals.  Why? -- pressure from majority to make minority conform

25 Factors affecting Group Performance  Performance in the presence of others -- effect depends on type of task  Performance on additive tasks vs. nominal groups Process Loss Social Loafing -- effort per person decreases as group size increases

26 Social Loafing and Dealing with it  The tendency for people to reduce their efforts on common goal or simple tasks when their efforts are pooled. Dealing 1. Motivation. - Increase sense of personal responsibility. - Feel that contributions are important. 2. Identification. 3. Make the activity interesting. 4. Optimize interpersonal trust.

27 Groupthink  Definition: when groups make decisions that individual members are expected to confirm to.  Factors leading to groupthink: group cohesiveness (unnecessary according to Aldag & Fuller, 1993) group isolation pressure for conformity strong leader

28 Groupthink, cont.  Avoiding groupthink: group leaders should serve as impartial moderators Group members at every stage of the decision- making process should critically evaluate decision alternatives Groups should periodically break into smaller subgroups to discuss critical issues Group members should discuss issues with subordinates
