Social Systems Theory is an approach to understanding how societies and organizations work together. This theory is based on several key assumptions about the nature of social systems and how they function. In this article, we’ll explore these assumptions in-depth.

Assumption 1: Social Systems Are Complex

One of the fundamental assumptions of Social Systems Theory is that social systems are complex entities. They are made up of many different parts that interact with one another in various ways. These parts include individuals, organizations, institutions, and cultural norms.

Example: In a company, employees from different departments interact with each other to complete tasks. These departments have their own goals and objectives but need to work together to achieve the company’s overall mission.

Assumption 2: Social Systems Are Dynamic

Another key assumption of Social Systems Theory is that social systems are dynamic. They are constantly changing and adapting to new situations. This means that they can never be fully understood or predicted because they are always in a state of flux.

Example: A community’s needs change over time as its population grows or shrinks. The community’s institutions must adapt to meet these changing needs.

Assumption 3: Social Systems Are Self-Organizing

Social Systems Theory assumes that social systems are self-organizing. This means that they have the ability to regulate themselves without external control or influence. They can create their own rules and norms and enforce them through socialization.

Example: An organization may develop its own culture over time, creating rules about how employees should behave and interact with one another.

Assumption 4: Social Systems Have Boundaries

Social Systems Theory asserts that social systems have boundaries that separate them from other social systems. These boundaries can be physical, institutional, or cultural in nature. They help to define the social system and differentiate it from other systems.

Example: A nation’s borders define the physical boundary of its social system, while its laws and institutions define its institutional boundaries.

Assumption 5: Social Systems Are Interdependent

Finally, Social Systems Theory assumes that social systems are interdependent. This means that they rely on one another for resources, support, and cooperation. No social system can exist in isolation.

Example: An organization relies on its employees to achieve its goals, while those employees rely on the organization for their livelihoods.


In summary, Social Systems Theory is based on several key assumptions about the nature of social systems. These assumptions include the complexity, dynamism, self-organizing nature, boundaries, and interdependence of social systems. By understanding these assumptions, we can gain a deeper insight into how societies and organizations function and interact with one another.
