Groups • When individuals are in groups, they act differently than do when they are alone. – football, – Parties –… Gpi. IC-2 A Group behavior 1

Introduction • As we know, people needs social interaction, that can be satisfied in the group context. • Group performance: – 2+2 = 3 – 2+2 = 5 – …, it depends on the group. Gpi. IC-2 A Group behavior 2

Group Definition • Two or more individuals, interacting and interdependent, who have come together to achieve particular objectives. • People with interpersonal relations as friendship, affection, belongingness or that have similar points of view. Gpi. IC-2 A Group behavior 3

Classifying Groups • Formal groups. – Those defined by the organization’s structure, with designated work assignments establishing tasks. • Informal groups. – Are alliances that are neither formally structured nor organizationally determined. – Appears in response to the need for social contact. Gpi. IC-2 A Group behavior 4

Formal groups classification • Command group – Subordinates who report directly to a given manager. • Task group – Those working together to complete a job task. Gpi. IC-2 A Group behavior 5

Informal groups classification • Interest group – Thos working together to attain a specific objective with which each is concerned. • Friendship group – Those brought together because they share one or more common characteristics Gpi. IC-2 A Group behavior 6

Why do people join groups? • • • Security. Status. Self-Esteem. Affiliation. Power. Goal Achievement. Gpi. IC-2 A Group behavior 7

Stages of group development • Five stage model. – The classical: Forming, storming, Norming, performing y adjourning. • The punctuated-equilibrium model. Gpi. IC-2 A Group behavior 8

Five stage model. • The classical one: – Forming: uncertainty, testing the waters. – Storming: Intragroup conflict, resist the constraints. – Norming: relationship and cohesiveness. – Performing: fully functional. – Adjournment: wrapping up activities. Gpi. IC-2 A Group behavior 9

Forming • Characteristics: – – caution, observation Diffused group objectives Low performance, ¿which is mi role? ¿who are the others? • Actions: – Animate to participate – Clarify project objectives, the time table, the roles, . . Gpi. IC-2 A Group behavior 10

Forming (subgroups) • Characteristics: – – – Affinity subgroups, comfort. Objectives clarification Assigning tasks to subgroups Performance improvement Blockage /Group thinking • Actions: – Integrate - disaggregate subgroups Gpi. IC-2 A Group behavior 11

Storming • Characteristics: – – – Conflicts generalization identification of key points Cohesion improvement productivity improvement Subgroups structure change Auto-admiration • Actions: conflicts resolution – Constructive confrontation, problem resolution – Identify supra-ordinary objectives – Every body is needed to achieve the objectives. Gpi. IC-2 A Group behavior 12

Norming • Characteristics: – – Formal rules establishment Evaluation of members because they differences Good personal relations Danger if excess or relations and structure • Actions: – Redirect the group toward the objective, remind to people their function – facilitator, advance assessment in accordance with the plan – Know and celebrate the success Gpi.

Gpi. IC-2 A Group behavior 14

The punctuated-equilibrium model. – – Phase 1 (50% assigned time) Transition Phase 2 (high performance) Completion performance High Low Transition completion First meeting Phase 1 A Phase 2 (A+B)/2 Gpi. IC-2 A Group behavior B 15

Sociometry • An analytical technique for studying group interactions • Seeks to find out who people like or dislike and whom they would or would not wish to work with. – Who would you like to associate within the process of carrying out your job? – Name several members with who you would like to spend some of your free time. . . Gpi. IC-2 A Group behavior 16

Sociometry • Social networks: Specific set of linkages among a defined set of individuals. • Clusters: Groups that exist within social networks. • Prescribed clusters: Formal groups like departments, work teams, task forces, or committees. • Emergent clusters: informal, unofficial groups • Coalitions: temporary union with specific purpose. • Cliques: Relatively permanent informal Groups that involve friendship. • Stars: Individuals with the most linkages in a network. • liaisons: Individuals in a social network who connect to two or more clusters but are not members of any cluster. • Bridges: Individuals in a social network who serve as linking pins by belonging to two or more clusters. • Isolates: Individuals who are not connected to a social network Gpi.

Why are some group effort more successful than others? Group member resources external Conditions imposed on the group Group task Group process Performance and satisfaction Group structure Gpi. IC-2 A Group behavior 18

External Conditions imposed on the group • • Organization Strategy. Authority Structures Formal Regulations Organizational Resources Human Resource Selection Process Performance Evaluation and Reward System Organizational Culture Physical work setting Gpi. IC-2 A Group behavior 19

Group member resources • Abilities – Individuals who hold crucial abilities for attaining the group’s task tend to be • more involved in group activity, generally contribute more , • more likely to emerge as group leaders, • more satisfied if their talents are effectively utilized by the group. • Personality Characteristics. – Sociability, self-reliance and independence. Gpi. IC-2 A Group behavior 20

Group structure • • • Formal Leadership. Roles Norms Status Size Composition Gpi. IC-2 A Group behavior 21

Roles – “All the world’s a stage, and all the men and women merely players” Shakespeare • All group members are actors, each playing a role. • Definition: – By this term, we mean a set of expected behavior patterns attributed to someone occupying a given position in a social unit. • We are required to play a a number of diverse roles, both on and off our jobs.

Gpi. IC-2 A Group behavior 28

The “How” and “Why” of norms • Norms develop gradually as group members learn what behaviors are necessary for the group to function effectively. • Develop in the following ways: – – Explicit statements made by a member Critical events in the group history. Primacy (The first behavior pattern) Carry-over behaviors from past situations Gpi. IC-2 A Group behavior 29

What makes a norm important? • If it facilitates the group’s survival. • If it increases the predictability of group members’ behavior. • If it reduces embarrassing interpersonal problems for group members. • If it allows members to express the central value of the group and clarify what is distinctive about the group’s identity Gpi.

IC-2 A Group behavior 32

Size • Depends on what dependent variables you look at. • Problem solving -> Big (12) • Gaining diverse input. • Completing tasks -> Smaller (7) • Faster • Best: Odd number and from 5 to 7 m. Gpi. IC-2 A Group behavior 33

Big groups and social loafing. • The tendency for individuals to expend less effort when working collectively than when working individually. Gpi. IC-2 A Group behavior 34

Composition • skills and knowledge < > • Group demography – Degree to which members of a group share a common demographic attribute, such as age, sex, race, educational level, or length of service in the organization – < > better but difficult – Turnover greater if <> Gpi. IC-2 A Group behavior 35

cohesiveness • Degree to which group members are attracted to each other and are motivated to stay in the group. • Determinants – Time spent together – Size (small) – Experience external threats • Cohesiveness is important because is correlated with group productivity Gpi. IC-2 A Group behavior 36

Relationship: cohesiveness, performance norms and productivity Cohesiveness Performance norms High Low High Low productivity Gpi. IC-2 A Group behavior productivity Moderate to low productivity 37

To encourage group cohesiveness. . . • • Make the group smaller Agreement with group goals Increase time spend together Increase status and difficulty to enter. Stimulate competition with other groups Rewards to the group Isolate the group Gpi. IC-2 A Group behavior 38
