The Systems View
“When we try to pick out anything by itself, we find it hitched to everything else in the Universe.”
– John Muir, naturalist and wilderness advocate
Our world is composed of systems—from ecosystems in nature to organizations and technologies in human society. Learning to see, understand, and think in systems is important because many of the biggest challenges facing our world today are the product of system failures and require a systems view to solve.
What is a system?
As Buckminster Fuller famously observed, a system is greater than the sum of its parts. What makes it greater are the interactions and relationships between those parts. Systems thinking educator Linda Booth Sweeney provides a helpful framework for thinking about this, making a distinction between a “system” —where the whole has properties the parts don’t— and a “heap,” or collection of things which has no higher function.
System or Heap?
Imagine a house. A house is a system, made up of many parts that interact together to provide shelter and other services like electricity and plumbing. But if a tornado hits the house and it’s destroyed, it can no longer serve these functions. All the materials and parts may still be there, but the relationships between those parts have been broken and now lie in a purposeless heap.
Systems take many forms. They can be very large (Earth itself is a system) and very small (e.g. a cell). Systems may be physically tangible (like the house) or abstract, such as a governmental system or computer network. They can also be a combination of both. What makes a system a system is that it is composed of “an interconnected set of elements that [are] coherently organized in a way that achieves something (function or purpose).” (Meadows)
Properties of systems
Systems are diverse but they share properties that can help us identify and understand them. Every system has one or more boundaries and may be separated into components or sub-systems. Every system is also contained within multiple higher level super-systems. These features are found across multiple system types and levels.
For example, a door is a system found in a building at a boundary opening. The function of the door is to allow some things to enter and exit the building while keeping other things from crossing the boundary. A door typically consists of two sub-systems: a closure and a means to control that closure, each of which can take diverse forms. The door might be made of wood with hinges and a latch, for example, or it might be a curtain with a hook to hold it aside.
A door is in turn embedded in higher-level super-systems (a wall, a building, a city, the local habitat). Adjacent systems may exist at any of these system levels and can influence the system of interest and may serve similar functions. Adjacent systems at the level of the door might include windows, which also mediate a boundary. At the level of the building, utility systems connect it to other systems.
In biology, a transmembrane protein in a cell wall performs a function similar to a door. It allows certain molecules or signals into the cell and passes other molecules and signals out to the external system. The cell in turn may be part of an organ (super-system), that is connected and served by an adjacent circulatory system that knits together many other systems that keep an organism (another super-system) alive.
Everything is connected

One of the key insights gained from a systems view is that everything is connected. No organism can survive completely in isolation from other living things—human beings included. All living things depend on resources and ecosystem services made available through interconnected webs of relationships that compose the living system that is Earth itself. The human-built world is similarly interwoven and complex; no problem or design solution exists in isolation. They are inextricably part of systems of material and energy flows, relationships, and information.
Since the world is full of complex systems, taking a systems view can be a very effective means to understand a design challenge at a deeper level and identify appropriate points for intervention. For a biomimetic designer, being knowledgeable about and aware of system interconnections can help you optimize design outcomes while considering how well your design fits within Earth’s context.
