Group Dynamics

Because many tasks in today’s world have become so complex, groups and teams have become an essential component of an organization’s success. The success of the group depends on the successful management of its members and making sure all aspects of work are fair for each member. Being able to work in a group is a key skill for managers and employees alike.

What is a groupgroupA collection of individuals who interact with each other such that one person’s actions have an impact on the others.? A group is a collection of individuals who interact with each other such that one person’s actions have an impact on the others. In organizations, most work is done within groups, and managing groups is key to each of the P-O-L-C functions. How groups function has important implications for organizational productivity. Groups where people get along, feel the desire to contribute, and are capable of coordinating their efforts may have high performance levels, whereas those characterized by extreme levels of conflict or hostility may demoralize members of the workforce.

In organizations, groups can be classified into two basic types: informal and formal. Informal work groupsinformal work groupsGroups made up of two or more individuals who are associated with one another in ways not prescribed by the formal organization. are made up of two or more individuals who are associated with one another in ways not prescribed by the formal organization. For example, a few people in the company who get together to play tennis on the weekend would be considered an informal group. A formal work groupformal work groupA group made up of managers, subordinates, or both with close associations among group members that influence the behavior of individuals in the group. is made up of managers, subordinates, or both with close associations among group members that influence the behavior of individuals in the group. We will discuss many different types of formal work groups later on in this chapter.

American organizational psychologist Bruce Tuckman presented a robust model in 1965 that is still widely used today. On the basis of his observations of group behavior in a variety of settings, he proposed a four-stage map of group evolution, known as the Forming-Storming-Norming-Performing ModelForming-Storming-Norming- Performing ModelA model proposed by Bruce Tuckman in 1965 involving a four-stage map of group evolution..[587] Later he enhanced the model by adding a fifth and final stage, adjourningadjourningThe fifth and final stage of the Tuckman model.. The phases are illustrated in the Stages of the Group Development Model. Interestingly enough, just as an individual moves through developmental stages such as childhood, adolescence, and adulthood, so does a group, although in a much shorter period of time.

According to this theory, to facilitate a group successfully, the leader needs to move through various leadership styles over time. Generally, this is accomplished by first being more direct, eventually serving as a coach, and later, once the group is able to assume more power and responsibility for itself, shifting to delegator.

While research has not confirmed that this is descriptive of how groups progress, knowing and following these steps can help groups be more effective. For example, groups that do not go through the storming phase early on will often return to this stage toward the end of the group process to address unresolved issues. Another example of the validity of the group development model involves groups that take the time to get to know each other socially in the forming stage. When this socialization occurs, groups tend to handle future challenges better because the individuals have an understanding of each other’s needs.

Stages of the Group Development Model

In the FormingformingThe stage in which the group comes together for the first time. stage, the group comes together for the first time. The members may already know each other or they may be total strangers. In either case, there is a level of formality, some anxiety, and a degree of guardedness as group members are not sure what is going to happen next. “Will I be accepted? What will my role be? Who has the power here?” These are some of the questions participants think about during this stage of group formation. Because of the large amount of uncertainty, members tend to be polite, conflict avoidant, and observant. They are trying to figure out the “rules of the game” without being too vulnerable. At this point, they may also be quite excited and optimistic about the task, perhaps experiencing a level of pride at being chosen to join a particular group.

Group members are trying to achieve several goals at this stage, although this may not necessarily be done consciously. First, they are trying to get to know one another. Often this can be accomplished by finding some common ground. Members also begin to explore group boundaries to determine what will be considered acceptable behavior. “Can I interrupt? Can I leave when I feel like it?” This trial phase may also involve testing the appointed leader or seeing whether a leader emerges from the group. At this point, group members are also discovering how the group will work in terms of what needs to be done and who will be responsible for each task. This stage is often characterized by abstract discussions about issues to be addressed by the group; those who like to get moving can become impatient with this part of the process. This phase is usually short in duration, perhaps a meeting or two.

Once group members feel sufficiently safe and included, they tend to enter the StormingstormingGroup members begin to explore their power and influence and they often stake out their territory by differentiating themselves from the other group members rather than seeking common ground. phase. Participants focus less on keeping their guard up as they shed social facades, becoming more authentic and more argumentative. Group members begin to explore their power and influence, and they often stake out their territory by differentiating themselves from the other group members rather than seeking common ground. Discussions can become heated as participants raise conflicting points of view and values, or disagree over how tasks should be done and who is assigned to them. It is not unusual for group members to become defensive, competitive, or jealous. They may take sides or begin to form cliques within the group. Questioning and resisting direction from the leader is also quite common. “Why should I have to do this? Who designed this project in the first place? What gives you the authority to tell me what to do?”

Although little seems to get accomplished at this stage, it actually serves an important purpose: group members are becoming more authentic as they express their deeper thoughts and feelings. What they are really exploring is “Can I truly be me, have power, and be accepted?” During this chaotic stage, a great deal of creative energy that was previously buried is released and available for use, but it takes skill to move the group from Storming to Norming. In many cases, the group gets stuck in the Storming phase.

Once group members discover that they can be authentic and that the group is capable of handling differences without dissolving, they are ready to enter the next stage, NormingnormingThe stage in which participants find it easy to establish their own ground rules (or norms) and define their operating procedures and goals..

As you may have noted, the five-stage model we have just reviewed is a linear process. According to the model, a group progresses to the Performing stage, at which point it finds itself in an ongoing, smooth-sailing situation until the group dissolves. In reality, subsequent researchers, most notably Joy H. Karriker, have found that the life of a group is much more dynamic and cyclical in nature.[588] For example, a group may operate in the Performing stage for several months. Then, because of a disruption, such as a competing emerging technology that changes the rules of the game or the introduction of a new CEO, the group may move back into the Storming phase before returning to Performing. Ideally, any regression in the linear group progression will ultimately result in a higher level of functioning. Proponents of this cyclical model draw from behavioral scientist Connie Gersick’s study of punctuated equilibriumpunctuated equilibriumThe theory that change within groups occurs in rapid, radical spurts rather than gradually over time..[589]

The concept of punctuated equilibrium was first proposed in 1972 by paleontologists Niles Eldredge and Stephen Jay Gould, who both believed that evolution occurred in rapid, radical spurts rather than gradually over time. Identifying numerous examples of this pattern in social behavior, Gersick found that the concept applied to organizational change. She proposed that groups remain fairly static, maintaining a certain equilibrium for long periods. Change during these periods is incremental, largely due to the resistance to change that arises when systems take root and processes become institutionalized. In this model, revolutionary change occurs in brief, punctuated bursts, generally catalyzed by a crisis or a problem that breaks through the systemic inertia and shakes up the deep organizational structures in place. At this point, the organization or group has the opportunity to learn and create new structures that are better aligned with current realities. Whether the group does this is not guaranteed. In sum, in Gersick’s model, groups can repeatedly cycle through the Storming and Performing stages, with revolutionary change taking place during short transitional windows. For organizations and groups who understand that disruption, conflict, and chaos are inevitable in the life of a social system, these disruptions represent opportunities for innovation and creativity.

CohesioncohesionThe degree of camaraderie within the group. can be thought of as a kind of social glue. It refers to the degree of camaraderie within the group. Cohesive groups are those in which members are attached to each other and act as one unit. The more cohesive a group, the more productive it will be and the more rewarding the experience will be for the group’s members.[590] Cohesive groups tend to have the following characteristics: they have a collective identity; they experience a moral bond and a desire to remain part of the group; they share a sense of purpose, working together on a meaningful task or cause; and they establish a structured pattern of communication.

The fundamental factors affecting group cohesion include the following:

  • Similarity. The more similar group members are in terms of age, sex, education, skills, attitudes, values, and beliefs, the more likely the group will bond.

  • Stability. The longer a group stays together, the more cohesive it becomes.

  • Size. Smaller groups tend to have higher levels of cohesion.

  • Support. When group members receive coaching and are encouraged to support their fellow team members, group identity strengthens.

  • Satisfaction. Cohesion is correlated with how pleased group members are with one another’s performance, behavior, and conformity to group norms.

As you might imagine, there are many benefits in creating a cohesive group. Members are generally more personally satisfied and feel greater self-confidence and self-esteem in a group where they feel they belong. For many, membership in such a group can be a buffer against stress, which can improve mental and physical well-being. Because members are invested in the group and its work, they are more likely to regularly attend and actively participate in the group, taking more responsibility for the group’s functioning. In addition, members can draw on the strength of the group to persevere through challenging situations that might otherwise be too hard to tackle alone.

Despite the advantages of cohesion, too much cohesion can be detrimental to a group. Because members can come to value belonging over all else, an internal pressure to conform may arise where some members modify their behavior to adhere to group norms. Members may become conflict avoidant, focusing on trying to please one another so as not to be ostracized. In some cases, members might censor themselves to maintain the party line. As such, the group is dominated by a superficial sense of harmony and discourages diversity of thought. Having less tolerance for deviants, who threaten the group’s static identity, cohesive groups will often disapprove of members who dare to disagree. Members attempting to make a change may be criticized, undermined, or even ostracized by other members, who perceive their attempts as a threat to the status quo. The painful possibility of being marginalized can keep many members in line with the majority.

The more strongly members identify with the group, the easier it is to see outsiders as inferior or, in extreme cases, as enemies. It is easy to see how this can lead to increased insularity. This form of prejudice can have a downward spiral effect. The group is not getting corrective feedback from within its own confines, and it is closing itself off from input and a cross-fertilization of ideas from the outside. In such an environment, groups can easily adopt extreme ideas that will not be challenged. Denial increases as problems are ignored and failures are blamed on external factors. With limited, often biased, information and no internal or external opposition, groups like these can make disastrous decisions.

GroupthinkgroupthinkA group pressure phenomenon that increases the risk of the group making flawed decisions by allowing reductions in mental efficiency, reality testing, and moral judgment. is a group pressure phenomenon that increases the risk of the group making flawed decisions by allowing reductions in mental efficiency, reality testing, and moral judgment. A famous example of groupthink is the decision to invade Cuba made by President John F. Kennedy and his cabinet in 1961. In a matter of days, Cuban forces repelled the invaders, whose objective was to overthrow the entire Cuban government, resulting in many casualties and captured troops. In retrospect, there were many reasons why the Bay of Pigs invasion was doomed from the start, but the planning and approval were characterized by a belief that the insiders knew best and did not need to consider “devil’s advocate” points of view. As this example illustrates, groupthink is a serious risk in highly cohesive groups.[591]

Cohesive groups can go awry in much milder ways. For example, group members can value their social interactions so much that they have fun together but spend little time on accomplishing their assigned task. Or a group’s goal may begin to diverge from the larger organization’s goal and those trying to uphold the organization’s goal may be criticized (for example, students may tease the class “brain” for doing well in school).

In addition, research shows that cohesion leads to acceptance of group norms.[592] Groups with high task commitment tend to do well, but suppose you belong to a group in which the norms are to work as little as possible! As you might imagine, these groups accomplish little and can actually work together against the organization’s goals.

Groups with high cohesion and high task commitment tend to be the most effective.


Social loafingsocial loafingThe tendency of individuals to put in less effort when working in a group context. refers to the tendency of individuals to put in less effort when working in a group context. This phenomenon, also known as the Ringelmann effect, was first noted by French agricultural engineer Max Ringelmann in 1913. In one study, he had people pull on a rope individually and in groups. He found that as the number of people pulling increased, the group’s total pulling force was less than the sum of individual efforts had been when measured alone.[593]

Why do people work less hard when they are working with other people? Observations show that as the size of the group grows, this effect becomes larger as well.[594] The social loafing tendency is not so much a matter of laziness as a matter of perceiving that one will receive neither one’s fair share of rewards if the group is successful nor blame if the group fails. Rationales for this behavior include, “My own effort will have little effect on the outcome.” “Others aren’t pulling their weight, so why should I?” Or “I don’t have much to contribute, and no one will notice anyway.” This is a consistent effect across a great number of group tasks and countries.[595] Research also shows that perceptions of fairness are related to less social loafing.[596] Therefore, teams that are deemed as more fair should also see less social loafing.

Collective efficacycollective efficacyA group’s perception of its ability to successfully perform well. refers to a group’s perception of its ability to successfully perform well.[597] A group with high collective efficacy is one whose members share a belief in the group’s capability to pursue its agreed-upon course of action and attain its goals. Collective efficacy is influenced by a number of factors, including watching others (“that group did it and we’re better than them”), verbal persuasion (“we can do this”), and how a person feels (“this is a good group”). Research shows that a group’s collective efficacy is positively related to its performance.[598] In addition, this relationship is stronger when task interdependence (the degree an individual’s task is linked to someone else’s work) is high rather than low.
