feedback

The most common use of this term is the idea of a ‘feedback loop’. This derives from systems thinking and explorations into cybernetics in the 1950s as electronic computers emerged on the scene.
An example of a feedback mechanism is a temperature control on a heating system. When the temperature drops below a set level, the heating cuts in to boost the temperature back to that level and then cuts out.
Seeking ‘feedback’ from customers is now a common business practice and acknwowledges the ‘relationship’ between producer and consumer.
