Feedback Loops: Feedback loops determine if a system is resilient or not.
Feedback loops determine if a system is resilient or not. Feedback is when a change in one thing changes a second thing, and then the change in the second thing loops back around and changes the first. There are two different kinds of feedback loops: negative and positive. In negative feedback loops, the change to the first thing is reduced by the change in the second thing, and the overall changes to the system are balanced out. Negative feedback loops prevent further changes from happening and can make a system resilient. Positive feedback loops are when a change causes more changes. If a change causes an increase to the first thing, then the effect will be more increases elsewhere. Positive feedback loops make systems spiral out of control.
