The Concept of a Group: A Fundamental Building Block in Organizations

Every organization – whether a school, a hospital, or a corporation – runs on the collective effort of people working together. Yet, not every collection of people qualifies as a group. What exactly transforms a set of individuals into a group? In organizational behavior, the concept of a group is far more specific than it appears. Understanding it is fundamental to grasping how organizations function, how decisions get made, and how goals get achieved.

What is a group? 🔗

At its most basic, a group is a collection of two or more individuals who interact with each other such that one person’s actions have an impact on the others. But that description only scratches the surface. A group is not merely a gathering of people in the same space. A crowd waiting at a bus stop, for instance, is not a group in the organizational sense – they share a location but not a common purpose, structured roles, or mutual influence.

What makes a group is the presence of shared objectives, ongoing interaction, and a degree of interdependence among members. In an organizational setting, groups form around specific objectives – to solve problems, complete tasks, or share knowledge – and they operate as the basic unit through which most organizational work gets done.

How scholars define a group 🔗

Researchers in organizational behavior have offered several precise definitions of a group, each highlighting a slightly different dimension of what it means to belong to one.

Edgar H. Schein 🔗

Edgar H. Schein, a foundational organizational psychologist and former professor at the MIT Sloan School of Management, defined a group as a collection of individuals who interact with one another in a structured manner to accomplish a goal or task. Schein’s definition draws attention to the element of structure – a group is not a random assembly but an organized set of relationships directed toward a purpose. His broader work on organizational psychology emphasized that understanding how people coordinate in groups is central to understanding organizations themselves.

D.H. Smith 🔗

D.H. Smith defines a group as two or more individuals who share a common purpose and interact in ways that influence one another. Smith’s framing places mutual influence at the heart of what a group is. Members are not passive participants; they actively shape each other’s attitudes, decisions, and behaviors. This makes the group dynamic rather than static – it evolves as members interact over time.

Jennifer 🔗

Jennifer, another organizational behavior theorist, describes a group as a collection of individuals who have some degree of interdependence, common goals, and the ability to work together toward achieving those goals. Her definition introduces the idea of capacity for collaboration – it is not enough for members to share goals; they must also be capable of working together to achieve them. This perspective is especially relevant in organizational settings where groups are assembled not just for social purposes but for task performance.

Gareth 🔗

Gareth approaches the definition from a social angle, describing a group as a system of people working together with shared responsibilities, mutual respect, and a sense of belonging. Where other definitions focus on task and structure, Gareth highlights the relational and social bonds that develop within a group. This perspective acknowledges that groups are not purely functional – they also serve human needs for connection and belonging.

Taken together, these definitions converge on a core idea: a group is a structured collection of individuals who come together, interact, and rely on each other to achieve a shared objective. The structural, relational, and goal-oriented dimensions are all part of what makes a group a group.

Essential characteristics of a group 🔗

Understanding the concept of a group requires looking at what actually holds it together. Several distinct characteristics define any group and influence how it functions. Here are the five most fundamental ones.

1. Common goals 🔗

Every group exists for a reason. Common goals are the very reason for a group’s existence – they provide direction, motivation, and a basis for coordination. Whether the goal is completing a project, improving departmental performance, or simply offering peer support, it is the shared objective that draws individuals into a collective and keeps them oriented toward the same outcome. Without a common goal, individuals may occupy the same physical space but remain functionally separate.

2. Member interaction 🔗

Interaction is what transforms a collection of individuals into a functioning group. A group’s members have regular contact and frequent interaction, and it is through this interaction that coordination, communication, and task performance become possible. Interaction can be face-to-face or virtual, formal or informal – but it must be ongoing and purposeful. A department where employees simply work in parallel without communicating would not, in the strict organizational sense, constitute a group.

3. Mutual influence 🔗

One of the defining features of a group is that one person’s actions impact the others. Members influence each other’s thinking, behavior, and decisions – this is what distinguishes a group from a mere collection of individuals. A new team member’s enthusiasm can energize the whole group; a disengaged member can dampen collective morale. Mutual influence can reinforce positive behaviors just as easily as it can spread negative ones, which is why managing group dynamics matters so much in organizational settings.

4. Identification among members 🔗

Over time, group members begin to develop a shared sense of identity – a feeling that they belong to something larger than themselves. Each group develops its own characteristics and uniqueness that members come to associate with. This identification fosters loyalty, commitment, and a shared responsibility for outcomes. Research published in the Journal of Organizational Behavior confirms that stronger team identity is directly linked to better task performance – when members see themselves as part of a unified group, they are more motivated to contribute and cooperate.

5. Interdependent behavior 🔗

Perhaps the most critical characteristic of any group is interdependence – the reality that what one member does affects others, and that no single member can achieve the group’s goal alone. High interdependence typically requires high levels of interaction and coordination among members. In practice, this means that a group functions like interconnected parts of a system: a researcher who does not complete their data collection holds up the analyst; a designer who misses a deadline delays the developer. Interdependence fosters a culture of accountability, mutual support, and shared responsibility.

Why these characteristics matter in organizations 🔗

These five characteristics – common goals, interaction, mutual influence, identification, and interdependence – are not just academic abstractions. They have direct implications for how organizations are structured and how work is performed. Since jobs in organizations are becoming more complex and interdependent, the use of groups in performing task functions will become increasingly important.

When a group is well-formed – with clearly stated goals, open channels of communication, and a strong sense of shared identity – it can achieve outcomes that no individual could accomplish alone. Conversely, when these characteristics are weak or absent, groups become prone to conflict, disengagement, and underperformance. Employees in well-functioning groups motivate one another, share knowledge, and support each other in times of stress – outcomes that extend well beyond formal job requirements.

It is also worth noting that individuals within a group may vary in their level of commitment to shared goals. Simply belonging to a group does not guarantee equal motivation or engagement. This is why managers must actively nurture the conditions – clarity of purpose, psychological safety, fair role distribution – that allow groups to function at their best.

Groups in context: formal and informal 🔗

Groups are either formal or informal. Formal groups – such as departments, project teams, and task forces – are deliberately created by the organization to achieve specific objectives. They operate with defined roles, reporting structures, and authority. Informal groups, on the other hand, emerge organically from social interactions among employees, driven by shared interests, friendships, or proximity. Both types are important. Formal groups deliver the structured output the organization needs; informal groups shape culture, morale, and the informal networks through which real communication often flows.

Understanding both dimensions is part of understanding what a group truly is – not just a functional unit, but a human system with its own dynamics, norms, and social fabric.

What do you think? Given the five characteristics discussed above, can you think of a situation where a group existed in name but lacked one or more of these essential features – and how did that affect its performance? And in your experience, which characteristic do you believe is the hardest for organizations to cultivate: genuine mutual influence, or a strong sense of member identification?
