Tools and Resources for Systems Thinkers

For a more detailed discussion of certain core concepts, see our systems thinking fundamentals.

Balancing Loop (Negative Feedback Loop) A process that counteracts change and attempts to achieve equilibrium or stability. Example: You need food for sustenance. When you haven’t eaten in a while, you feel hungry. Once you eat, you feel less hungry, balancing food consumption.

Causal Loop Diagram A visual tool that maps the cause-and-effect relationships among different variables in a system, showing how they influence one another.

Complexity A characteristic of systems with many interconnected parts. It makes outcomes difficult to predict because small changes can have large, unexpected effects.

Delay The time gap between an action and its observable effect in a system. Delays make it difficult to learn from interventions and can lead to overcorrection.

Emergent Property A characteristic or behavior that arises from interactions within a system but isn’t present in any individual component. Example: A decrease in an area’s affordability emerging from successful talent attraction.

Feedback Loop A circular chain of cause and effect in which a change in one element eventually influences itself, either amplifying (reinforcing) or dampening (balancing) the original change.

Iceberg Model A framework for understanding systems at multiple levels: events (what just happened), patterns (what trends exist) and structures (what influences the patterns).

Interconnection The relationships and linkages among different elements in a system that allow them to influence one another.

Leverage Point A place in a system where a small change can produce significant shifts in behavior or outcomes. Not all intervention points are equally powerful.

Mental Model The deeply held beliefs, assumptions and values that shape how people understand the way a system works and what actions are appropriate.

Reinforcing Loop (Positive Feedback Loop) A process that amplifies change, creating exponential growth or decline. Example: Money in your bank account grows with interest. The more money in your account, the more interest is paid, compounding the amount of money you save.

Root Cause The fundamental, underlying reason for a problem, as opposed to symptoms of the problem. Systems thinking seeks to address root causes rather than surface-level events.

Silo A state of working in isolation from other parts of a system, typically with limited awareness of interdependencies or unintended consequences in other areas.

Stock An accumulation or quantity in a system that can be measured at any given time. Example: The number of rabbits in an ecosystem or the amount of affordable housing units in a community.

System A set of interconnected elements organized to achieve a purpose and in which changing one part affects other parts and the whole.

Systems Change Shifting the underlying structures, relationships, power dynamics and mental models that produce current outcomes, rather than addressing symptoms.

Systems Mapping The process of creating visual representations of how different elements in a system relate to and influence one another.

Systems Thinking An approach to problem-solving that views issues as part of an interconnected whole rather than as isolated parts, focusing on relationships, patterns and contexts.

Unintended Consequences Outcomes that were not anticipated or planned when an intervention was designed, often a result of overlooking system interconnections.

Whac-a-Mole A metaphor for solving problems in isolation without understanding system dynamics, in which fixing one issue causes another to emerge elsewhere.
