Related Terms. Process in which the effect or output of an action is 'returned' (fed-back) to modify the next action. Feedback is essential to the working and survival of all regulatory mechanisms found throughout living and non-living nature, and in man-made systems such as education system and economy. As a two-way flow, feedback is inherent to all interactions, whether human-to-human, human-to-machine, or machine-to-machine.
