Systems theory
Systems theory is the transdisciplinary study of systems, i.e. cohesive groups of interrelated, interdependent components that can be natural or artificial. Every system has causal boundaries, is influenced by its context, defined by its structure, function and role, and expressed through its relations with other systems. A system is “more than the sum of its parts” when it expresses synergy or emergent behavior.
Changing one component of a system may affect other components or the whole system. It may be possible to predict these changes in patterns of behavior. For systems that learn and adapt, the growth and the degree of adaptation depend upon how well the system is engaged with its environment and other contexts influencing its organization. Some systems support other systems, maintaining the other system to prevent failure. The goals of systems theory are to model a system’s dynamics, constraints, conditions, and relations; and to elucidate principles (such as purpose, measure, methods, tools) that can be discerned and applied to other systems at every level of nesting, and in a wide range of fields for achieving optimized equifinality.
General systems theory is about developing broadly applicable concepts and principles, as opposed to concepts and principles specific to one domain of knowledge. It distinguishes dynamic or active systems from static or passive systems. Active systems are activity structures or components that interact in behaviours and processes or interrelate through formal contextual boundary conditions (attractors). Passive systems are structures and components that are being processed. For example, a computer program is passive when it is a file stored on the hard drive and active when it runs in memory. The field is related to systems thinking, machine logic, and systems engineering.
Systems theory is a framework for understanding how different parts of a system work together to produce an outcome. It focuses on the interactions and relationships between components, such as the inputs, processes, and outputs of an organization, and how the system adapts to its environment through feedback loops. The purpose is to study the interconnected whole rather than isolated pieces, as the system’s properties are more than the sum of its parts.
Key components and concepts
- Inputs: The resources, materials, or information that enter the system.
- Process: The operations or activities that transform inputs into outputs.
- Outputs: The products or results of the system’s processes.
- Feedback: The control element that provides information on the output, allowing the system to adapt and adjust.
- Holism: The idea that a system’s properties are emergent and cannot be understood by simply analyzing its individual parts.
- Interdependence: The components of a system are connected and influence each other.
- Homeostasis: The system’s ability to maintain a state of steadiness and stability despite external changes.
Applications and examples
- Family therapy: Social workers and therapists view a family’s dynamics as a system, looking at how relationships and interactions influence individual members’ behavior.
- Business and organizations: Systems theory is used to analyze how a company’s different departments and processes interact to achieve goals, shifting from a focus on individual tasks to the whole organization.
- Ecology: Systems ecology studies the complex interactions between organisms and their environment, treating an ecosystem as a single, complex system.
- Engineering: Systems engineering is an interdisciplinary approach to developing and deploying successful systems by considering the entire lifecycle and all its components.

While there is no single, universally agreed-upon list of “7 principles” for general systems theory, core concepts include holism, interconnectedness, transformation (inputs to outputs), feedback loops, boundaries, goal-seeking, and the idea of equifinality. These principles view any system as an integrated whole with interacting parts, rather than a collection of isolated components.
Core principles of general systems theory
- Holism: The idea that a system’s properties cannot be understood by analyzing its parts in isolation; the whole is greater than the sum of its parts.
- Interconnectedness: Elements within a system are interconnected and interdependent. The failure or success of one part affects the entire system.
- Transformation process: Systems transform inputs into outputs. This process is a fundamental characteristic of all systems, especially in living systems where it is often cyclical.
- Feedback loops: Systems use feedback to regulate themselves and maintain a state of equilibrium. Information from the output is fed back into the system as input to adjust performance.
- Boundaries: Each system has a boundary that separates it from its environment and other systems. These boundaries can be physical or conceptual.
- Goal-seeking: Systems are often goal-oriented, meaning their interactions are directed toward achieving a specific goal or final state.
- Equifinality: In an open system, the final state can be reached through different paths and from different initial conditions. This is in contrast to closed systems, where the outcome is fully determined by the initial state.
