At work, a feedback loop is a continuous and iterative process where an individual or team receives feedback, learns, and improves performance. More technically, a feedback loop is about cause and effect, where the output (the feedback) becomes a constructive input (improved product or performance). At the organizational level, customer feedback on the design of your product would be the output that becomes the input needed to redesign your product and create a better offering for your customer (thus creating a full circle).
