Group Structure

Work groups are organized structured elements

Work groups are organized and have structural elements that help the members understand who is responsible for what tasks, what kind of behaviors are expected of group members, and more. These structural elements include roles, norms, and status. Groups are also influenced by size and the degree of group cohesiveness.


Elon Musk

Elon Musk is perhaps best known as one of the world’s richest men, an entrepreneur, investor, and business magnate. 

He is the founder, CEO, and chief engineer at SpaceX; angel investor, CEO and Product Architect of Tesla, Inc.; founder of The Boring Company; and co-founder of Neuralink and OpenAI. He’s also a father of seven children, heads a private foundation and a media influencer.

These are all roles that Elon Musk has to manage in his everyday life.

A role is a set of expected behavior patterns attributed to someone occupying a given position in a social unit. Within a role there is:

  • Role identity: the certain actions and attitudes that are consistent with a particular
  • Role perception: our own view of how we ourselves are supposed to act in a given We engage in certain types of performance based on how we feel we’re supposed to act.
  • Role expectations: how others believe one should act in a given situation
  • Role conflict: conflict arises when the duties of one role conflict with the duties of another

Elon Musk

Let’s look at this through the lens of a day in the life of Elon Musk. First, let’s look at him in the role of CEO. When he’s looking for project third party expertise, he may visit the CEOs of other successful corporations. He may shake hands, have some lunches, get some commitments for projects from these CEOs. That’s role identity. The actions and attitudes that are consistent with a CEO.

Elon Musk may choose to wear a suit and tie when he visits these CEOs. He may use “corporate speak” that’s familiar to them. He may purchase the lunch. That might be Elon Musk’s role perception. It’s the way he thinks he should behave in the CEO role.

Later, he and his brother, Kimbal may hold a press conference where he announces to the world that they’ve funded renewable energy projects for schools across the nation. Responses include headlines of “Yay, Elon!” People talk on Facebook about how Elon and Kimbal are really helping communities. They are meeting our role expectations for them.

Finally, Elon races out of the press conference, fight traffic to the airport, and try to get home to the football gamer of this oldest child. This is role conflict. The duties of one of Elon’s roles is in conflict   with another—demands arise from both and need to be managed.


Norms are the acceptable standards of behavior within a group that are shared by the members.

In our Motivation course we discussed about motivation, we discussed about the Hawthorne Studies. For those who may not have taken this course yet, Hawthorne Electric in the U.S hired researchers to do a study to determine if higher levels of light increased the production of a work group.

A full-scale appreciation of group behavior and its influence on work groups was uncovered by the Hawthorne Studies in the 1930s. What was discovered was that groups established a set of behaviors. Some of these behaviors were spurred on simply because they were being observed. In other situations, the group collectively established a group norm of production—and those individuals that violated the norm by overachieving were ridiculed for not following the established, albeit unspoken, norms.

There are common classes of norms:

  • Performance norms: the group will determine what is an acceptable level of effort, product and outcome should exist in the workplace.
  • Appearance norms: the group will determine how members should dress, when they should be busily working and when they can take a break, and what kind of loyalty is shown to the leader and company.
  • Social arrangement norms: the group regulates interaction between its members.
  • Allocation of resources norms: the group or the organization originates the standards by which pay, new equipment, and even difficult tasks are assigned.

If you wish to be accepted by a particular group, you may conform to that group’s norms even before you’ve become a part of it. Conformity is adjusting one’s behavior to align with the norms of a particular group. By watching and observing that group to better understand its expectations, you are using the group as a reference group. A reference group is an important group to which individuals belong or hope to belong and with whose norms individuals are likely to conform.

When people act outside a group’s norms—perhaps a manager makes sexual advances to his assistant, or one co-worker spreads vicious rumors about another—this is referred to as deviant workplace behavior.


The socially defined position or rank given to groups or group members by others is called status. Status seems to be something we cannot escape. No matter what the economic approach, we always seem to have classes of people. Even the smallest of groups will be judged by other small groups, opinions will be made, reputations will be earned, and status will be assigned.

Status characteristics theory suggests that difference in status characteristics create status hierarchies within groups. People who lead the group, control its resources, or make enormous contributions to its success tend to have high status. People who are attractive or talented may also have high status

High status members are often given more leeway when it comes to the group’s norms, too, and it makes them more at ease about resisting conformity. If you ever watched television’s medical drama House, the very talented, intelligent and curmudgeonly main character is allowed to act unconventionally and often inappropriately, largely because the diagnostic talents he brings to the group are so rare and valued.

He is often assertive and outspoken with the other group members. He’s addicted to pain medications, he hates people and lets everyone know it, and yet his behaviors are tolerated. He’s a high status contributor to the group and they need his talents badly, so they overlook his failure to conform to their norms.

In spite of the high status members taking advantage of the norms and dominating group interactions, equity is an important part of status. We talked a bit about how perceived equity is a motivator for people. If status is observed when rewards and resources are distributed among the group members, then usually all is well.


Does the size of a group affect its dynamics? You bet! But how size affects the group depends on where you’re looking.

As a rule, smaller groups are faster than their larger counterparts. But when it comes to decision making, larger groups end up scoring higher marks. So, if there’s a decision to be made, it’s wise to poll a larger group . . . and then give the input to a smaller group so they can act on it.

A side note about size: groups with odd numbers of people tend to operate better than those that have an even number, as it eliminates the issue of a tie when votes are taken. Groups of five or seven tend to be an ideal size, because they’re still nimble like a smaller group, but they make solid decisions like a larger group does.


Cohesiveness is the degree to which group members enjoy collaborating with the other members of the group and are motivated to stay in the group.

Obstacles and roadblocks are commonplace in the business world. Leaders embrace risk and understand that they must be taken to grow. Leaders embrace change. Managers, on the other hand, like routine and status quo, if we are to understand the assessments of researchers correctly. As a leader-manager, you will need to assess the roadblocks you see and innovate new solutions to overcome them. Some may work and some may not

Cohesiveness is the degree to which group members enjoy collaborating with the other members of the group and are motivated to stay in the group.

The graphic shows the relationship between performance norms and cohesiveness. In the workplace, there are ways to increase cohesiveness within a group.

A group leader can:

  • shrink the size of the group to encourage its members get to know each other and can interact with each other.
  • increase the time the group spends together, and even increase the status of the group by making it seem difficult to gain entry to it.
  • help the group come to agreement around its goals.
  • reward the entire group when those goals are achieved, rather than the individuals who made the biggest contributions to it.
  • stimulate competition with other groups.
  • isolate the group physically.

All of these actions can build the all-important cohesiveness that impacts productivity.

Now that we fully understand what a group is and what its dynamics are, shall we go build one to work on a project? Or . . . wait. Are we better off letting one individual person tackle that particular task? We’ll discuss in the next lesson about making the choice between assigning an individual to work on a project, versus assigning a group.
