Systems theory is an interdisciplinary study of systems as they relate to one another within a larger, more complex system. The key concept of systems theory is that the whole is greater than the sum of its parts. This means that when holistically examining how smaller systems come together to affect the greater complex system, certain characteristics of the whole—the complex system—can not be easily explained or rationalized when looking singularly at any one of its systems—its parts.
Key Facts
- System: A system is an entity made up of interrelated and interdependent parts. It can be natural or artificial and can range from small-scale systems to large-scale complex systems.
- Complex System: A complex system refers to the greater whole system made up of individual smaller systems. It is generally used in social sciences and encompasses the interactions and relationships between the smaller systems.
- Ecological Systems: Ecological systems are the various systems in an individual’s life that influence their behavior. These systems can include family, community, school, work, and cultural systems.
- Homeostasis: Homeostasis refers to the state of steady conditions within a system. It is the tendency of a system to maintain stability and balance.
- Adaptation: Adaptation is a system’s tendency to make changes that will protect itself when presented with new environmental factors. It allows the system to adjust and respond to changes in its surroundings.
- Feedback Loop: A feedback loop occurs when the outputs of a system ultimately affect its inputs, causing the system to feed back into itself circularly. This feedback loop can influence the behavior and functioning of the system.
System
A system is an entity made up of interrelated and interdependent parts. It can be natural or artificial and can range from small-scale systems to large-scale complex systems. Systems are characterized by their inputs, outputs, and mechanisms for feedback.
Complex System
A complex system refers to the greater whole system made up of individual smaller systems. It is generally used in social sciences and encompasses the interactions and relationships between the smaller systems. Complex systems exhibit emergent properties, which are characteristics that arise from the interactions of the system’s components but are not present in any of the components individually.
Ecological Systems
Ecological systems are the various systems in an individual’s life that influence their behavior. These systems can include family, community, school, work, and cultural systems. Ecological systems theory posits that an individual’s behavior and development are shaped by the interactions between these systems.
Homeostasis
Homeostasis refers to the state of steady conditions within a system. It is the tendency of a system to maintain stability and balance. Homeostasis is achieved through feedback loops, which allow the system to adjust and respond to changes in its environment.
Adaptation
Adaptation is a system’s tendency to make changes that will protect itself when presented with new environmental factors. It allows the system to adjust and respond to changes in its surroundings. Adaptation can occur through various mechanisms, such as natural selection, learning, or technological innovation.
Feedback Loop
A feedback loop occurs when the outputs of a system ultimately affect its inputs, causing the system to feed back into itself circularly. This feedback loop can influence the behavior and functioning of the system. Feedback loops can be positive, reinforcing the system’s behavior, or negative, counteracting the system’s behavior.
