Systems thinking

Impression of systems thinking about society[1]

Systems thinking is the process of understanding how those things which may be regarded as systems influence one another within a complete entity, or larger system. In nature, systems thinking examples include ecosystems in which various elements such as air, water, movement, plants, and animals work together to survive or perish. In organizations, systems consist of people, structures, and processes that work together to make an organization "healthy" or "unhealthy".

Systems thinking has roots in the General

Examples of systems

Some examples:

Systems science thinking is increasingly being used to tackle a wide variety of subjects in fields such as computing, engineering, epidemiology, information science, health, manufacture, management, sustainable development, and the environment. Professor Rajagopal, EGADE Business School, building on the work of Ferdinand Tönnies has suggested the application of systems thinking in developing marketing strategy from the perspectives of corporate business restructuring in the post-economic recession situations.[6]

Applications

As a result of such thinking, new insights may be gained into how the supermarket works, why it has problems, how it can be improved or how changes made to one component of the system may impact the other components.

  • a "profit making system" from the perspective of management and owners
  • a "distribution system" from the perspective of the suppliers
  • an "employment system" from the perspective of employees
  • a "materials supply system" from the perspective of customers
  • an "entertainment system" from the perspective of loiterers
  • a "social system" from the perspective of local residents
  • a "dating system" from the perspective of single customers
  • Using the tenet of "multifinality", a supermarket could be considered to be:
  • Encapsulation of a system in space and/or in time
  • Active and passive systems (or structures)
  • Transformation by an activity system of inputs into outputs
  • Persistent and transient systems
  • Evolution, the effects of time passing, the life histories of systems and their parts.
  • Design and designers.

A treatise on systems thinking ought to address many issues including:

  • Interdependence of objects and their attributes - independent elements can never constitute a system
  • Holism - emergent properties not possible to detect by analysis should be possible to define by a holistic approach
  • Goal seeking - systemic interaction must result in some goal or final state
  • Inputs and outputs - in a closed system inputs are determined once and constant; in an open system additional inputs are admitted from the environment
  • Transformation of inputs into outputs - this is the process by which the goals are obtained
  • Entropy - the amount of disorder or randomness present in any system
  • Regulation - a method of feedback is necessary for the system to operate predictably
  • Hierarchy - complex wholes are made up of smaller subsystems
  • Differentiation - specialized units perform specialized functions
  • Equifinality - alternative ways of attaining the same objectives (convergence)
  • Multifinality - attaining alternative objectives from the same inputs (divergence)

The systems thinking approach incorporates several tenets:[5]

The systems approach

Systems science and the application of systems science thinking has been grouped into the following three categories based on the techniques or methodologies used to design, analyze, modify, or manage a system:

A holistic system is any set (group) of interdependent or temporally interacting parts. Parts are generally systems themselves and are composed of other parts, just as systems are generally parts or holons (see Holon Philosophy) of other systems.

  • a system is a dynamic and complex whole, interacting as a structured functional unit circuit
  • energy, material and information flow among the different elements that compose a system
  • a system is a community situated within an environment
  • energy, material and information flow from and to the surrounding environment via semi-permeable membranes or boundaries that may include negotiable limits
  • systems are often composed of entities seeking equilibrium but can exhibit patterns, cycling, oscillation, randomness or chaos (see Chaos Theory), or exponential behavior (see Exponential Function)

Systems science thinkers consider that:

  • a system is composed of parts
  • all the parts of a system must be related (directly or indirectly), else there are really two or more distinct systems
  • a system is encapsulated (has a boundary)
  • the boundary of a system is a decision made by an observer, or a group of observers
  • a system can be nested inside another system
  • a system can overlap with another system
  • a system is bounded in time, but may be intermittently operational
  • a system is bounded in space, though the parts are not necessarily co-located
  • a system receives input from, and sends output into, the wider environment
  • a system consists of processes that transform inputs into outputs
  • a system is autonomous in fulfilling its purpose (a car is not a system. A car with a driver is a system)

Several ways to think of and define a system include:

Systems science thinking attempts to illustrate how small catalytic events that are separated by distance and time can be the cause of significant changes in silo effect. Systems thinking techniques may be used to study any kind of system — physical, biological, social, scientific, engineered, human, or conceptual.

In systems science, it is argued that the only way to fully understand why a problem or element occurs and persists is to understand the parts in relation to the whole.[4] Standing in contrast to Descartes's scientific reductionism and philosophical analysis, it proposes to view systems in a holistic manner. Consistent with systems philosophy, systems thinking concerns an understanding of a system by examining the linkages and interactions between the elements that compose the entirety of the system.

Systems thinking has been defined as an approach to problem solving, by viewing "problems" as parts of an overall system, rather than reacting to specific parts, outcomes or events, and thereby potentially contributing to further development of unintended consequences. Systems thinking is not one thing but a set of habits or practices[3] within a framework that is based on the belief that the component parts of a system can best be understood in the context of relationships with each other and with other systems, rather than in isolation. Systems thinking focuses on cyclical rather than linear cause and effect.
