Feedback is an interesting thing, I've only recently become aware of just how useful feedback systems are, not only in business or management, but rather from a personal perspective in creating the appropriate change in any form of behaviour. In fact that is, almost by definition, what feedback does.

A feedback loop is created by taking some proportion of a systems output, and feeding it back into the input. This then appends the input and will change the throughput and as such the outputof the system. This sounds all well and good from a process perspective, but what does it actually mean? To massively simplify it means that if you are aware of your actions, your actions change.
