Structure Drives Behavior
A system's behavior is produced by its structure, the way its parts and flows are arranged, not by the intentions or quality of the people inside it. To change the behavior, change the structure. Conway's Law is a special case: an organization's communication structure shapes...
Start with the lens that recurring outcomes usually follow from system structure.

Stocks and Flows
A stock is an accumulation, the amount of something present in a system at a moment in time. Flows are the rates that fill or drain it. Stocks are the memory of a system; they change only through their flows. Stocks change gradually even when flows change abruptly, which is th...
Use stocks and flows to name the things that accumulate, drain, and constrain behavior.

Feedback Loops
A feedback loop forms when the level of a stock influences the flows that change that same stock, so the system acts on itself. There are two kinds: reinforcing loops that amplify and balancing loops that stabilize. Feedback is what makes a system generate its own behavior ove...
Then look at how system behavior reinforces itself or pushes back toward balance.

Delays
The time lag between a change in a flow and the system's response to it. Information and material take time to move through a system, so feedback always arrives some interval after the cause. Delays are a primary cause of oscillation, overshoot, and instability. A balancing lo...
Add timing, because delayed effects often explain why interventions surprise teams.

System Traps
Recurring structures that reliably produce problematic behavior regardless of who is involved: systemic archetypes such as policy resistance, tragedy of the commons, drift to low performance, escalation, success to the successful, addiction (shifting the burden), rule beating,...
Read traps before solutions so symptoms are not mistaken for causes.

Leverage Points
Places in a system where a small intervention can produce a large change in behavior. Meadows ranks them from weak (adjusting parameters and numbers) to strong (changing rules, information flows, goals, and the paradigm the system arises from). Effort spent on low leverage poi...
Move from diagnosis to where a small change might alter system behavior.

Complexity
Anything about the structure of a system that makes it hard to understand and modify. Complexity is defined by how the system appears to the people working on it, not by its size or line count. Complexity is the primary force that slows software development over a system's lif...
Close by grounding the path in the playbook view of complexity.
