What is another name for informal and interpersonal rules that team members are expected to follow?

What Is a Group?

The literature of group dynamics is a very rich field of study and includes many definitions of work groups. For example, we might conceive of a group in terms of perceptions; that is, if individuals see themselves as a group, then a group exists. Or, we can view a group in structural terms. For instance, McDavid and Harari define a group as “an organized system of two or more individuals who are interrelated so that the system performs some function, has a standard set of role relationships among its members, and has a set of norms that regulate the function of the group and each of its members.”2 Groups can also be defined in motivational terms as “a collection of individuals whose existence as a collection is rewarding to the individuals.”3 Finally, a group can be viewed with regard to interpersonal interactions—the degree to which members communicate and interact with one another over time.4

By integrating these various approaches to defining groups, we may conclude for our purpose here that a group is a collection of individuals who share a common set of norms, generally have differentiated roles among themselves, and interact with one another toward the joint pursuit of common goals. (The definitions of roles and norms is provided later in this chapter.) This definition assumes a dynamic perspective and leads us to focus on two major aspects of groups: group structure and group processes. Group structure is the topic of this chapter, and group processes will be discussed in later chapters.

Types of Groups

There are two primary types of groups: formal and informal. Moreover, within these two types, groups can be further differentiated on the basis of their relative degree of permanence. The resulting four types are shown in Table 9.1.

Formal Groups. Formal groups are work units that are prescribed by the organization. Examples of formal groups include sections of departments (such as the accounts receivable section of the accounting department), committees, or special project task forces. These groups are set up by management on either a temporary or permanent basis to accomplish prescribed tasks. When the group is permanent, it is usually called a command group or functional group. An example would be the sales department in a company. When the group is less permanent, it is usually referred to as a task group. An example here would be a corporate-sponsored task force on improving affirmative action efforts. In both cases, the groups are formal in that they are both officially established by the company to carry out some aspect of the business.

Informal Groups. In addition to formal groups, all organizations have a myriad of informal groups. These groups evolve naturally out of individual and collective self-interest among the members of an organization and are not the result of deliberate organizational design. People join informal groups because of common interests, social needs, or simply friendship. Informal groups typically develop their own norms and roles and establish unwritten rules for their members. Studies in social psychology have clearly documented the important role of these informal groups in facilitating (or inhibiting) performance and organizational effectiveness. Again, on the basis of their relative degree of permanence, informal groups can be divided into friendship groups (people you like to be around) and interest groups (e.g., a network of working women or minority managers). Friendship groups tend to be long-lasting, whereas interest groups often dissolve as people’s interests change.

One of the more interesting aspects of group processes in organizations is the interaction between informal and formal groups. Both groups establish norms and roles and goals and objectives, and both demand loyalty from their members. When an individual is a member of many groups—both formal and informal—a wide array of potentially conflicting situations emerges that has an impact upon behavior in organizations. We will focus on this interplay throughout the next few chapters.

Reasons for Joining Groups

People join groups for many reasons. Often, joining a group serves several purposes at once. In general, at least six reasons can be identified for joining groups:

1. Security. Most people have a basic need for protection from external threats, real or imagined. These threats include the possibility of being fired or intimidated by the boss, the possibility of being embarrassed in a new situation, or simply the anxiety of being alone. Groups can be a primary source of security against such threats. We have often heard that there is “safety in numbers.”
2. Social Needs. In addition, as discussed in previous chapters, basic theories of personality and motivation emphasize that most individuals have relatively strong social needs. They need to interact with other people and develop meaningful relationships. People are clearly social creatures. Groups provide structured environments in which individuals can pursue friendships.
3. Self-Esteem. Similarly, membership in groups can assist individuals in developing self-esteem. People often take pride in being associated with prestigious groups; note such examples as professors elected to membership in the National Academy of Sciences or salespeople who qualify for a million dollar club as a reward for sales performance.
4. Economic Self-Interest. People often associate with groups to pursue their own economic self-interest. Labor unions are a prime example of this phenomenon, as are various professional and accrediting agencies, such as the American Bar Association. These organizations often attempt to limit the supply of tradespeople or professionals in order to maintain employment and salaries.
5. Mutual Interest. Some groups are formed to pursue goals that are of mutual interest to group members. Included here are bridge clubs, company-sponsored baseball teams, and literary clubs. By joining together, individuals can pursue group goals that are typically not feasible alone.
6. Physical Proximity. Finally, many groups form simply because people are located in close physical proximity to one another. In fact, office architecture and layout can have considerable influence over the development of social networks and groups. Consider, for example, two floors in the same building. On the first floor, all the managers have private offices arranged in a long row, with their assistants arranged in a similar row in front of them. This horizontal pattern of offices does not allow for frequent interaction between either the managers or the secretaries, and as a result group formation may be slowed. On the second floor, however, suppose all the managers’ offices are arranged in a cluster surrounding a similar cluster of assistants. The result would be more frequent social interaction among employees. This is not to say that one arrangement is superior to the other; rather, it is simply to point out how variations in office arrangements can have an impact on group formation.

Stages in Group Development

Before we begin a comprehensive examination of the structure of groups, consider briefly the stages of group development. How do groups grow and develop over time? Tuckman has proposed one model of group development that consists of four stages through which groups generally proceed.5 These four stages are referred to by the deceptively simple titles forming, storming, norming, and performing (see Exhibit 9.2).

1. Forming. In the first stage of development, when group members first come together, emphasis is usually placed on making acquaintances, sharing information, testing one another, and so forth. This stage is referred to as forming. Group members attempt to discover which interpersonal behaviors are acceptable or unacceptable in the group. In this process of sensing out the environment, a new member is heavily dependent upon others for providing cues to acceptable behavior.
2. Storming. In the second stage of group development, a high degree of intergroup conflict (storming) can usually be expected as group members attempt to develop a place for themselves and to influence the development of group norms and roles. Issues are discussed more openly, and efforts are made to clarify group goals.
3. Norming. Over time, the group begins to develop a sense of oneness. Here, group norms emerge (norming) to guide individual behavior. Group members come to accept fellow members and develop a unity of purpose that binds them.
4. Performing. Once group members agree on basic purposes, they set about developing separate roles for the various members. In this final stage, role differentiation emerges to take advantage of task specialization in order to facilitate goal attainment. The group focuses its attention on the task (performing). As we consider this simple model, it should be emphasized that Tuckman does not claim that all groups proceed through this sequence of stages. Rather, this model provides a generalized conceptual scheme to help us understand the processes by which groups form and develop over time.
