6 Organizations and Their Structures
Explore how organizational structures, shared expectations, routines, and relationships coordinate work and shape how people respond to change.
Organizations as social systems
An organization is more than a collection of people or a chart of job titles. As a , it coordinates people and groups through recurring relationships, roles, rules, information, and shared meanings as they pursue common purposes.
Its parts are interdependent: a change in staffing, procedures, or priorities can affect how other parts work. Structure, culture, and relationships therefore shape one another.
Formal and informal structures
Organizations have both formal and informal structures. sets out responsibilities, authority, and approved procedures. develops through everyday interactions, as colleagues seek advice from trusted peers, form alliances, and create unofficial ways to solve problems.
The formal chart shows who is authorized to make a decision, while the informal network can help explain whose knowledge or influence actually shapes it. Understanding an organization involves examining both its formal design and the interactions through which members carry it out and sometimes change it.
Authority and division of work
A arranges roles or offices in levels of authority. In a bureaucracy, a chain of command identifies who supervises whom, while a assigns specialized tasks to different positions. Written rules and records can make decisions more consistent and responsibilities clearer.
These arrangements can help coordinate complex work, but strict rules or narrow job boundaries can slow responses when circumstances change or when a problem crosses departmental lines. is only one way to organize authority: some groups use more decentralized or participatory decision-making. Even without a formal chain of command, groups still need ways to share information, make decisions, and coordinate responsibilities.
Culture and shared expectations
consists of shared understandings that influence how members interpret situations and act. It appears in stated values and formal policies, as well as in everyday language, rituals, expectations, and assumptions. For example, members may share expectations about whether it is acceptable to question a supervisor or ask another team for help.
Members learn these expectations through socialization and interaction. Groups within the same organization may also develop distinct subcultures.
and changing work
are recognizable patterns of repeated action, such as a shift handover, a weekly planning meeting, or a standard way to approve a request. They help people coordinate and preserve useful knowledge.
are not necessarily unchanging. Members may adapt them when a problem arises, and repeated adjustments can gradually alter how work is done. A routine that once helped ensure reliability can become a source of delay if it no longer fits the task.
Relationships between groups
Organizations commonly contain subgroups such as departments, teams, professions, or work shifts. These groups can have different expertise, responsibilities, and priorities. include how they exchange information, coordinate tasks, compete for resources, and resolve disagreements.
Formal reporting lines may shape how groups work together, but informal relationships and networks of advice or cooperation matter too. Strong connections across groups can help people share knowledge. Weak coordination can lead to misunderstandings, duplicated work, or delays.
Coordination in a hospital
A hospital’s patient care may involve nurses, physicians, laboratory staff, and billing personnel. Each group has specialized duties and , but successful care depends on timely handoffs and clear communication across group boundaries.
A formal protocol can establish what information must be passed along. Professional norms and personal trust can influence whether people raise a concern or seek help. The example shows how , , culture, and relationships work together within one .
How organizational arrangements work together
Organizations coordinate people and groups through interconnected social arrangements. Hierarchies and divisions of labor allocate authority and tasks; culture shapes shared expectations; make recurring work predictable; and relationships link groups across organizational boundaries.
These arrangements can support coordination, but they can also create rigidity or barriers. Understanding an organization means considering both its formal design and the everyday interactions through which members carry out and sometimes change that design.
