Feedback is a process in which information about the past or the present influences the same phenomenon in the present or future. As part of a chain of cause-and-effect that forms a circuit or loop, the event is said to "feed back" into itself.
Ramaprasad (1983) defines feedback generally as "information about the gap between the actual level and the reference level of a system parameter which is used to alter the gap in some way," emphasising that the information by itself is not feedback unless translated into action. "...'feedback' exists between two parts when each affects the other..."
Feedback is also a synonym for:
- Feedback signal: The measurement of the actual level of the parameter of interest.
- Feedback mechanism: The action or means used to subsequently modify the gap.
- Feedback loop: The complete causal path that leads from the initial detection of the gap to the subsequent modification of the gap.
The Feedback Loop in Decision Making
Just making a decision, and implementing it is not the end of the decision-making process. It is crucial to monitor your decision regularly once it is implemented. At this stage, you have to keep a close eye on the progress made by implementing the solution. You may need to measure the results of implementation against your expected standards. Monitoring of solutions early on will help you close the feedback loop by altering your decisions, if you notice a deviation of results from your expectations.
In the end, you will be able to see what you did right and wrong when coming up and putting the decision to use and you may choose to revisit the past decision or take a different tact when faced with similar problems in the future.
