GROUP INFLUENCES

2. DEFINITION
According to Stephen Robbins,” A group may be defined as two or more individuals interacting and interdependent who have come together to achieve particular objectives’ According to Edgar.H.Schien “ A group may be defined as a social phenememon in which two or more persons decide to interact with one another ,share common ideaology and perceive themselves as a group.

3. NATURE OF GROUP
1)Two or More persons: To form a group there should be at least two persons because a single individual cannot interact. However there cannot be may any specific limit on the maximum number of persons in a group but the size of the group will be determined by rules and regulation of the organization . 2) Collective identity: Members of the group must be aware about the membership of the group. Each member of the group must believe that he is a member of , is a participant in, some specific groups. It is the awareness of each other that most clearly differentiates a group from an aggregation of individuals. In the case of aggregation of individuals , they are ordinarily not aware of one another or, if aware, do not interact with each other in a meaningful way

4. NATURE OF GROUP
3)Interaction: Members of the group interact among themselves. Interaction means that each member shares his ideas with others through communications and this communication can take place face to face in writing, over the telephone, across a computer network, or in any other manner which allows communication among group members. However, it is not necessary for all members of the group to interact simultaneously, but each member must interact at least occasionally with one or more members of the group 4) Shared Goal Interest: Members of the group should subscribe to the attainment of some common objectives. However, it is not necessary that each member subscribes to or agrees with all the objectives of the group. If a group has a variety of objectives or interests, each member of the group must share at least one of the group’s concerns. The shared goal interest binds the group member together

Two or more individuals interacting and interdependent, who have come together to achieve particular objectives.
Formal Group
A designated work group defined by the organization’s structure.
Informal Group
A group that is neither formally structured now organizationally determined; appears in response to the need for social contact.

12. Why People Join Groups Personal Attraction Safety & Security
Status & Self esteem
Opportunity for Interaction
Group Goal
Power

13. Reasons for Joining Group
Groups come into being for a number of reasons, which are as follows: 1)Personal Attraction: Even in formal group settings when people are required to work together, the strength and cohesion of the group will be determined by the extent that individuals find other members attractive 2) Safety and Security: Groups enable individuals to develop their belonging needs. Apart from the need to feel “loved, the group meets security needs as individuals feel protected by the group. 3) Status and Self esteem: Groups often develop a sense of worth and status that confers greater self esteem on members. These feelings are enhanced if membership is perceived to be exclusive or difficult 4) Opportunity for Interaction: Having opportunities to interact with and take part in group activities is essential if people are to develop the sense of affiliation with others.

14. Reasons for Joining Group
Groups come into being for a number of reasons, which are as follows: 5) Group Goal: Sharing a set of common objectives is important to building the sense of common purpose and the norms required for the maintenance of a sense of identity and the way the group differentiates itself 6) Power: Groups can exert more power when dealing with non group members than the collection of individuals would be able to achieve. For eg: trade union membership provides an opportunity for the employee group to both protect and promote employee interests.

17. The Five-Stage Model of Group Development
Forming Stage The first stage in group development, The forming stage represents a time where the group is just starting to come together and is characterized with anxiety and uncertainty.
Storming Stage The second stage in group development, is where conflict and competition are at its greatest. Issues related to the group's tasks, individual roles and responsibilities or even with the group members themselves are discussed.
Norming Stage The third stage in group development, characterized by close relationships and cohesiveness. Leadership is shared, and members are willing to adapt to the needs of the group.

18. …Group Development (cont’d)
Performing Stage
The fourth stage in group development, when the group is fully functional. The team has a shared vision and is able to stand on its own feet with no interference or participation from the leader. The team has a high degree of autonomy. 
Adjourning Stage
The final stage in group development is Adjourning – It is the break-up of the group, hopefully when the task is completed successfully, its purpose fulfilled; everyone can move on to new things, feeling good about what's been achieved.

19. DEFINITION OF GROUP EFFECTIVENESS
Team effectiveness (also referred to as group effectiveness) is the capacity a team has to accomplish the goals or objectives administered by an authorized personnel or the organization.
MODEL OF GROUP EFFECTIVENESS
Group effectiveness is influenced by multiple factors. A simplified model of group effectiveness has been conceptualized in terms of input, processes and outcomes.
In input variables, the model included organizational context –environment,structure,layout,technology,incentive system:
Nature of task – task complexity, procedure and group member resources – skills and abilities, work values, number of members.
Similarly, process variables included cohesiveness, norms,roles,decision making,synergy,social facilitation etc.
At outcome level the model includes quality, quantity timeliness of performance, group morale and members satisfaction.

20. MODEL OF GROUP EFFECTIVENESS
Based on various researchers following suggestions are made to improve group effectiveness
Groups exist within larger organizational context, Organizational structure, strategy, authority relationships, selection procedure, motivational structure, organizational layout and workflow etc will influence group productivity. Where organizational climate is supportive, resources are abundant and company follows meritocracy, group is likely to perform well. Managers should therefore look the group performance in context and try to provide supportive context.
2) Keep the groups smaller generally having five or seven members perform better performance due to better adherence to group norms and cohesiveness. Smaller groups also more satisfied members.
3) In order to collaborative norms organization should reward group performance rather than individual performance
4) Complex tasks requires more focused interaction as compare to simple tasks. Thus group will require more frequent an d more intense interaction for solving complex problems.
5) Group members if having requisite skills to tackle the problem, group's effectiveness will be high
6) If group’s goals are aligned with organizational goals and cohesiveness is high,

21. MODEL OF GROUP EFFECTIVENESS
group performance will be high. Thus managers need to encourage groups to internalize organizational goals. 7) Groups must use decisions techniques that minimizes the possibility of group think. 8) Managers need to encourage shared leadership concept where members can interchange the task and groups building roles. Self oriented behavior should be minimized. 9) To minimize social loafing develop task structure, specialized roles, and some measure to assess individual contribution to group achievement. 10) When the task is interdependent use effective communication and minimize conflict to enhance high productivity. 11) Groups within an organization should not pitted against each other to compete for scarce resources, instead emphasis should be on pooling and sharing of resources and work for super ordinate goals of organization 12) Educate and train group members in group process and group dynamics.

23. Group Processes
Group process refers to how an organization's members work together to get things done. Typically, organizations spend a great deal of time and energy setting and striving to reach goals, but give little consideration to what is happening between and to the group's greatest resource - its members. The Major group processes are as follows: 1) Group Norms: A norm is a rule of conduct that has been established by group members to maintain consistency in behavior. This tells the individual how to behave in a particular group. When agreed to and accepted by the group, norms act as a means of influencing the behavior of group members with a minimum of external controls. Norms differ among groups, communities and societies but they all have them. They are set of beliefs, feelings and attitudes commonly shard by group members. These are also referred to as rules or standards of behavior that apply to group members. All groups have established norms, that is, acceptable standards of behavior that are shared by the group’s members. 2) Group Cohesiveness: Cohesiveness is a measure of the attraction of the group to its members (and the resistance to leaving it), the sense of team spirit and the willingness

of its members to coordinate their efforts. Compared with members of a low cohesive group, those in high cohesive group will therefore be keen to attend meetings, be satisfied with the group use, be cooperative and friendly with each other and be more effective in achieving the aims they set for themselves. The low cohesive group will be marked by absenteeism, the growth of cliques and factions and a sense of frustration at the lack of attainment. 3) Decision Making: Decision-making is an act of choice wherein an individual or a group selects a particular course of action form the available alternatives in a given situation. Decision making is at the core of managerial planning. It involves establishing goals, defining tasks, searching for alternatives and choice of the best alternative. In an organization, decision making may be carried out by both individuals and groups. In modern organization facing the environmental uncertainties, group decision making has become almost indispensable.

25. Importance of Group
1)Performs Complex Task: Groups can be a means of working on a complex and independent tasks that are too complex for an individual to perform and that cannot be easily broken down into independent tasks 2) Generate New ideas: Groups can be a means of generating new ideas or creative solutions to solve problems that require inputs from a number of people. The multi various skills required for the performance of a complex and difficult job is available within a group. 3) Serves as a Liaison: Groups can serve as liaison or coordinating functions among several workgroups whose work is to some extent interdependent. 4) Facilitates Complex Decision Making: Groups can be used to facilitate the implementation of complex decisions. A group composed of representatives from various working groups can coordinated activities of these interrelated groups. In a large organization there will be number of problems, conflicting views etc for decision making.

26. Importance of Group
One needs a vehicle to air these views after due consideration. Only a powerful group can provide this as “Union is Strength” 5) Serves as Problem Solving Mechanism: Groups can serve as problem solving mechanism when problem requires the processing of complex information, interaction among members with different information and critical assessment of possible alternative solutions. 6) Serves as Vehicle of Socialization: Groups can be used as a vehicle of socialization and training. By bringing several people together into training situations, a common message can be imparted a common group perspective is developed. 7) Acts as a Agent: In order to share the common values and beliefs of the organization to the new employees the group cab be highly useful. The group educates the new employees will be more powerful and effective than by the authority of management.
