Using Causal Loop Diagrams is a great way to research and (re)design complex systems. Causal Loop Diagrams (CLD), is a tool developed from system dynamics to develop a better understanding of complex systems.

A causal loop diagram (CLD) is a causal diagram that aids in visualizing how different variables in a system are interrelated. A CLD consists of a set of nodes and edges. Nodes represent the variables and edges are the links that represent a connection or a relation between the two variables. A link marked positive indicates a positive relation and a link marked negative indicates a negative relation. A positive causal link means the two nodes change in the same direction, i.e. if the node in which the link starts decreases, the other node also decreases. Similarly, if the node in which the link starts increases, the other node increases as well. A negative causal link means the two nodes change in opposite directions, i.e. if the node in which the link starts increases, the other node decreases and vice versa. Wikipedia has a good simple explanation of the power of CLDs: https://en.wikipedia.org/wiki/Causal_loop_diagram

This site offers a great way to create simple CLDs in your browser: https://nocomplexity.com/causalloopdiagram/

You can save your CLDs and share them with others. Since creating CLDs often a team effort, use the remix button to build on CLDs of others.

CLDs can be used for creating architectures and designs so you can find CLDs in the Architecture Playbook.
