Abstract
The topic of the following report is the subject of Group Cohesion. A Group is defined as two or
more individuals, interacting and interdependent, who have come together to achieve particular
objectives. A group has certain properties that govern its functioning. One of the more important
properties of a group is its Cohesion. Group Cohesion is defined as the resultant of all the forces acting
on members to remain in the group. In this report we have discussed the definitions, characteristics and
dimensions of Group Cohesion. We have also explored the factors influencing Group Cohesion and also
Tuckman’s Five Stage Model of Group Development. We have reached the conclusion that while Group
Cohesion affords a great deal of benefits to both the group and the organization as a whole, it also has
certain disadvantages that can be detrimental to the organization and the group.

GROUPS
1
1.1 What is a Group?
Two or more individuals, interacting and interdependent, who have come together to achieve
particular objectives.
A collection of individuals who have regular contact and frequent interaction, mutual influence,
common feeling of camaraderie, and who work together to achieve a common set of goals.
Collection of individuals contributing to some common aim under the direction of a leader, and
who shares a sense of common identity.
Groups form to accomplish some objective. The objective may be to complete some kind of task or it
may be to promote the interpersonal relationships between the group members. Many groups,
however, fulfill both of these functions.
1.2 Common Characteristics of a Group
The common characteristics of a Group are as follows:
• Members engaged in frequent interaction;
• Those involved define themselves as group members;
• Others define members as belonging to a particular group;
• They share common norms and mutual interests;
• They identify with one another and share values;
• They feel a sense of collective responsibility;
• They act in a unified way towards the organization.
1.3 Types of Groups
Within many organizations different groups are formed at different levels. Some groups maybe
deliberately formed, some groups are formed through an informal setting. Below we discuss briefly two
forms of groups which are found within a company.1
Formal Task Groups
A formal group is created within an organization to complete a specific role or task. This may be to
oversee a launch of a particular product or service. A formal status and role is conferred upon the
group and its members by the organization. They have definite structures with prescribed
leadership and established rules, processes and roles. They tend to be permanent.
Informal Groups
Informal groups are established by individuals within the organization that a need to interact with
one another and who also believe that these informal groups meet a need that formal groups
cannot meet within the firm. An informal group is a network of personal and social relations. It is
not established or required by the formal organization but arises spontaneously as people interact
with each other.
Groups have 5 major properties:
Roles
The role is the expected behavior of the individuals within the group.
Norms
The norms are the accepted behavior of the individuals within a group.
Status
Status is the socially defined position or rank of the members of the group.
Size
A group’s size (number of members) can also determine how its members behave.
Cohesiveness
Extent to which the members of a group find staying together to be in mutual interest.
One of the most important properties of a group is Group Cohesion.

CHAPTER NO. 2
GROUP COHESION
1
2.1 Group Cohesion
A group is said to be in a state of cohesion when its members possess bonds linking them to one another
and to the group as a whole. According to Festinger, Schachter, and Back (1950), group cohesion was
believed to develop from a field of binding social forces that act on members to stay in the group.
Groups that possess strong unifying forces typically stick together over time whereas groups that lack
such bonds between members usually disintegrate.
More common terms for Group Cohesion are ‘Team Spirit’ and ‘Espirit de Corps’.
A few formal definitions for Group Cohesion:
Carron, Brawley, and Widmeyer (1998) – “A dynamic process that is reflected in the tendency of
a group to stick together and remain united in the pursuit of its instrumental objectives and/or
for the satisfaction of member needs”
Festinger - "The resultant of all the forces acting on members to remain in the group."
A dynamic process which is reflected in the tendency for a group to stick together and remain
united in the pursuit of goals and objectives.
2.2 Advantages of Group Cohesion
There are many benefits to group cohesiveness. Here are just four general benefits of having a group
that 'sticks together':
Improved Communication
The communication within the group is much more extensive. In other words, people who like
each other communicate better and more frequently with each other.
Positive Interactions
1
Groups that are more cohesive have positive interactions with one another. People are friendlier
and there is an increased feeling of the group as a whole. As a result, the group acts as a whole
not as individuals.
Success in achieving Goals
A group that has a high level of group cohesiveness is much more successful in achieving their
goal. The feeling of togetherness in the group motivates members to achieve the desired goal and
their efforts increase.
Increased Satisfaction
The members in groups that are cohesive are much more satisfied with that group. As a result,
they are more willing to stay in the group longer and often recommend the group to others.
Decreased Employee Turnover and Stress.
Increased Morale
Morale is the willingness of an individual, a team, an organization to win and to succeed. It is best
described as a grim determination to soldier on despite hardships, obstacles and failures. When
morale is high, organizations and individuals will keep focusing on a positive outcome. There is a
hope and even an expectation that final victory and success will be attained. When group cohesion
is high, each member of the group is confident of the support and help of his fellow members and
this in turn increases morale.
Effect on Productivity
Higher group cohesion ensures that the members of the team/group work together more
efficiently and effectively. This increases productivity.
Conformity
Conformity refers to yielding to group pressures when no direct request to comply with the group
is made. The more cohesive the group, the more influence the group has on its individual
members, the greater the conformity.

2.3 Factors affecting Group Cohesion
The forces that push group members together can be positive (group-based rewards) or negative
(things lost upon leaving the group). Often, these factors work through enhancing the identification of
the individual with the group she/he belongs to as well as their beliefs of how the group can fulfill their
personal needs. The main factors that influence group cohesiveness are: members’ similarity, group size,
entry difficulty, group success and external competition and threats.
Members’ Similarity
The more group members are similar to each other on various characteristics the easier it would
be to reach cohesiveness. Following Social Identity Theory, we know that people feel closer to those
whom they perceive as similar to themselves in terms of external characteristics (age, ethnicity) or
internal ones (values, attitudes). In addition, similar background makes it more likely that members
share similar views on various issues, including group objectives, how to communicate and the type of
desired leadership. In general, higher agreement among members on group rules and norms results in
greater trust and less dysfunctional conflict. This, in turn, strengthens both emotional and task
cohesiveness.
Group Size
Since it is easier for fewer people to agree on goals and to co-ordinate their work smaller groups
are more cohesive than larger groups. Task cohesiveness may suffer, though, if the group lacks enough
members to perform its tasks well enough.
Entry Difficulty
Difficult entry criteria or procedures to a group tend to present it in more exclusive light. The
more elite the group is perceived to be, the more prestigious it is to be a member in that group and
consequently, the more motivated members are to belong and stay in it. This is why alumni of
prestigious universities tend to keep in touch for many years after they graduate.
Group Success
1
Group success, like exclusive entry, increases the value of group membership to its members
and influences members to identify more strongly with the team and to want to be actively associated
with it.
External Competition and Threats
When members perceive active competition with another group, they become more aware of
members’ similarity within their group as well as seeing their group as a means to overcome the
external threat or competition they are facing. Both these factors increase group cohesiveness; leaders
throughout human history have been aware of this and focused the attention of their followers on
conflicts with external enemies when internal cohesion was threatened. Similar effects can be brought
about by facing an ‘objective’ external threat or challenge (such as natural disaster).

DIMENSIONS OF GROUP COHESION
1
3.1 About Dimensions of Group Cohesion
The bonds that link group members to one another and to their group as a whole are not
believed to develop spontaneously. Over the years, social scientists have suggested that cohesiveness
among group members can develop from various dimensions, including a heightened sense of
belonging, interpersonal attraction, and teamwork.
3.2 Group Unity
Many theorists believe that group cohesion results from a deep sense of “we-ness” or belonging
to a group as a whole. By becoming enthusiastically involved in the efforts of their group and by
recognizing the similarities that exist among group members, individuals tend to develop a close
connection with their group and its members. This sense of community strengthens the bonds of unity
that link group members to one another, ultimately fostering solidarity and cohesion.
1
3.3 Attraction
Some theorists believe that group cohesion has more to do with interpersonal attraction at both
individual- and group-levels. A group may be cohesive if:
1. Its members have positive feelings towards one another (individual-level attraction),
2. Its members have positive feelings towards the group (group-level attraction), or
3. Its members have positive feelings towards other members and the group as a whole.
1
According to Hogg (1992), group cohesiveness typically develops from a depersonalized attraction to
group members based on their status as group members, rather than a personal attraction based on
specific relationships. In addition to group cohesion, this depersonalized form of attraction has also been
linked to membership stability.
3.4 Teamwork
Other theorists stress that cohesion comes from group members’ commitment to work together
to complete their shared tasks and accomplish their collective goals. Members of task-oriented groups
typically exhibit great interdependence and often possess feelings of responsibility for the group’s
outcomes. The bonds of unity that develop from members’ concerted effort to achieve their common
goals are considered indicative of group cohesion.
1
Given that the construct of group cohesion has been conceptualized in so many different ways,
contemporary theorists assert that cohesion is a complex, multidimensional construct that cannot be
simplified to a single element or generalized across groups. While members of a hockey team may
exhibit teamwork as they attempt to score a goal, members of a group therapy session may develop
feelings of acceptance and a sense of belonging. The important thing to remember is that because
cohesion can be represented in many different forms, there is no such thing as a standard cohesive
group.

STUDY MODELS OF GROUP COHESION
4.1 Gersick's Punctuated Equilibrium model
Gersick's study of naturally occurring groups departs from the traditionally linear models
of group development. Her punctuated equilibrium model (Gersick, 1988, 1989, 1991) suggests
that groups develop through the sudden formation, maintenance, and sudden revision of a
"framework for performance". This model describes the processes through which such
frameworks are formed and revised and predicts both the timing of progress and when and how
1
in their development groups are likely, or unlikely, to be influenced by their environments. The
specific issues and activities that dominate groups' work are left unspecified in the model, since
groups' historical paths are expected to vary. Her proposed model works in the following way.
Phase I
According to the model, a framework of behavioral patterns and assumptions through which a
group approaches its project emerges in its first meeting, and the group stays with that
framework through the first half of its life. Teams may show little visible progress during this
time because members may be unable to perceive a use for the information they are
generating until they revise the initial framework.
Midpoint
At their calendar midpoints, groups experience transitions-paradigmatic shifts in their
approaches to their work-enabling them to capitalize on the gradual learning they have done
and make significant advances. The transition is a powerful opportunity for a group to alter the
course of its life midstream. But the transition must be used well, for once it is past a team is
unlikely to alter its basic plans again.
Phase 2
A second period of inertial movement, takes its direction from plans crystallized during the
transition. At completion, when a team makes a final effort to satisfy outside expectations, it
experiences the positive and negative consequences of past choices.
4.2 Tuckman Model
Although Bruce W. Tuckman (1938- ) is best known for his article 'Developmental sequence in
small groups,' published in 1965, his areas of expertise are educational research and educational
psychology. Nevertheless, of all the models of group development that have been proposed, Tuckman's
forming-storming-norming-performing is the one referenced most often.
1
The initial four-stage model came out of Tuckman's first job after grad school at the Naval
Medical Research Institute, Bethesda MD. He and a small group of social psychologists studied small
group behavior as applicable to U.S. Navy small-crew vessels and stations. The model didn't derive from
original research, but rather from a review of 50 articles, many of them psychoanalytic studies of
therapy and T-groups. While searching for a developmental sequence that would fit most groups in
these studies
Tuckman initially called the four stages: 1) orientation-testing-dependence; 2) conflict; 3) group
cohesion; and 4) functional role-relatedness. Since these labels didn't exactly role off the tongue,
Tuckman renamed the stages forming, storming, norming, and performing. These four stages have been
group development mainstays for over 50 years now, the memorable rhyme scheme no doubt helping
to promote their popularity
Forming
In the first stages of team building, the forming of the team takes place. The individual's
behavior is driven by a desire to be accepted by the others, and avoid controversy or conflict. Serious
issues and feelings are avoided, and people focus on being busy with routines, such as team
organization, who does what, when to meet, etc. But individuals are also gathering information and
impressions - about each other, and about the scope of the task and how to approach it. This is a
comfortable stage to be in, but the avoidance of conflict and threat means that not much actually gets
done.
The team meets and learns about the opportunities and challenges, and then agrees on goals
and begins to tackle the tasks. Team members tend to behave quite independently. They may be
motivated but are usually relatively uninformed of the issues and objectives of the team. Team
members are usually on their best behavior but very focused on themselves. Mature team members
begin to model appropriate behavior even at this early phase. Sharing the knowledge of the concept of
"Teams - Forming, Storming, Norming, Performing" is extremely helpful to the team.
Supervisors of the team tend to need to be directive during this phase.
1
The forming stage of any team is important because, in this stage, the members of the team get
to know one another, exchange some personal information, and make new friends. This is also a good
opportunity to see how each member of the team works as an individual and how they respond to
pressure.
Storming
Every group will next enter the storming stage in which different ideas compete for
consideration. The team addresses issues such as what problems they are really supposed to solve, how
they will function independently and together and what leadership model they will accept. Team
members open up to each other and confront each other's ideas and perspectives. In some cases
storming can be resolved quickly. In others, the team never leaves this stage. The maturity of some team
members usually determines whether the team will ever move out of this stage. Some team members
will focus on minutiae to evade real issues.
The storming stage is necessary to the growth of the team. It can be contentious, unpleasant
and even painful to members of the team who are averse to conflict. Tolerance of each team member
and their differences should be emphasized. Without tolerance and patience the team will fail. This
phase can become destructive to the team and will lower motivation if allowed to get out of control.
Some teams will never develop past this stage.
Supervisors of the team during this phase may be more accessible, but tend to remain directive
in their guidance of decision-making and professional behavior. The team members will therefore
resolve their differences and members will be able to participate with one another more comfortably.
The ideal is that they will not feel that they are being judged, and will therefore share their opinions and
views.
Norming
The team manages to have one goal and come to a mutual plan for the team at this stage. Some
may have to give up their own ideas and agree with others in order to make the team function. In this
stage, all team members take the responsibility and have the ambition to work for the success of the
team's goals.
1
Performing
It is possible for some teams to reach the performing stage. These high-performing teams are
able to function as a unit as they find ways to get the job done smoothly and effectively without
inappropriate conflict or the need for external supervision. By this time, they are motivated and
knowledgeable. The team members are now competent, autonomous and able to handle the decision-
making process without supervision. Dissent is expected and allowed as long as it is channeled through
means acceptable to the team.
Supervisors of the team during this phase are almost always participative. The team will make
most of the necessary decisions. Even the most high-performing teams will revert to earlier stages in
certain circumstances. Many long-standing teams go through these cycles many times as they react to
changing circumstances. For example, a change in leadership may cause the team to revert to storming
as the new people challenge the existing norms and dynamics of the team.
A fifth stage
In 1977 Tuckman and Mary Ann Jensen proposed an update to the popular model, again based
on a literature review. They reported that 23 newer articles "tended to support the existence of the four
stages" but also suggested a fifth stage. Tuckman and Jensen called this stage adjourning. Adjourning
basically involves dissolution that is, terminating roles, completing tasks, and reducing dependency.
Others have called this stage mourning, since former group members often experience loss—especially
when a group is dissolved suddenly or with little planning.
How valid and useful is the Tuckman model?
Though Tuckman's four-stage model has found its way into many textbooks, not every social
psychologist embraces it. For one thing, Tuckman's model suffers the same criticisms as any stage-
theory or lifespan model: By trying to paint a universal picture, it over-generalizes. Groups aren't so
straightforward. As with all human processes, every group deviates from any stage theory. What's more,
there's usually overlap between stages. Not only are the lines fuzzy, but the stages are nonlinear. Group
1
members are always balancing the needs to accomplish tasks and build relationships, and the focus
between the two constantly shifts. In other words, in real life group development is more like a spiral
than a series of clear-cut steps.
The other major criticism takes aim at the model's catchy labels. The concern is that facilitators
and trainers too often project these labels onto groups where the stages don't exist or aren't helpful.
But then, this is less a question of the four-stages' validity, than an example of how slogans and models
encourage intellectual laziness and misapplication.
All things considered, we've found Tuckman's model to sometimes be a helpful starting point for
small groups. There does seem to be a generally predictable developmental process for certain kinds of
small groups, and when people have some appreciation of this process, groups seem to gel a little
sooner.
4.3 Consequences of Group Cohesion
Group cohesion has been linked to a range of positive and negative consequences. Firstly,
members of cohesive groups tend to communicate with one another in a more positive fashion than
noncohesive groups. As a result, members of cohesive groups often report higher levels of satisfaction
and lower levels of anxiety and tension than members of noncohesive groups. Secondly, group cohesion
has been linked to enhanced group performance in non-laboratory-based groups. This bi-directional
relationship is strongest when the members of a group are committed to the group’s tasks.
Membership in a cohesive group can also prove problematic for members. As cohesion
increases, the internal dynamics (e.g., emotional and social processes) of the group intensify. As a result,
people in cohesive groups are confronted with powerful pressures to conform to the group’s goals,
norms, and decisions. In many instances these pressures to conform are so great that members suffer
from groupthink. Individuals who refuse to yield to the ways of the majority are typically met with
additional negative consequences, including hostility, exclusion, and scapegoating. Furthermore, group
cohesion can trigger distress and maladaptive behavior in members following changes to the structure
of the group (e.g., loss of a member).
