About feedback

    Feedback
    Despite the fact that the subject is understandable to everyone and, it would seem, simple, I want to touch on him in his first post.

    We all live in a world where any of our actions either follows some kind of answer or does not follow the answer. If there is no answer, we feel that something is wrong. Perhaps some do not feel the discomfort of the lack of feedback. But really - why worry if the restrictions are lifted and you can “be yourself,” as you can sometimes hear from young people.

    Feedback cannot be one-time. She is always and she is constant. For example, you always have “feedback from customer”. It is not one-time ("today is and will never be again") - but quite the contrary. The child will always tell you that he wants ice cream (or whatever he wants at that moment) when you walk with him. When any system, program, apparatus, or anything else is being designed, feedback is used to calibrate it and work correctly.

    But what if feedback is broken? If there is interference during the signal? If there is no feedback at all (everything disappeared is broken)?

    In this situation, we do not know what the customer or subordinate thinks of us. A person does not know whether it is hot or cold. Spacecraft plowing open spacesBolshoi Space Theater , losing contact with the MCC. Everything falls apart ...

    There are two types of feedback: positive and negative. Positive feedback is a type of communication where a change in the output signal of the system leads to such a change in the input signal that contributes to a further deviation of the output signal from the original value. Those. it is an explosion or collapse. But in any case, this is a clearly understandable ending and the end of the existence of a system / process / society. Negative feedback is a type of communication in which the output signal of the system is transmitted back to the input to cancel part of the input signal. Negative feedback makes the system more resistant to random changes in parameters. Those. it’s a tumbler, regulating itself, having a certain standard for adjustment.

    If you look from the point of view of processes and control - then all those processes that diverge into distant distances or vice versa - collapse to zero (well, that's how they were designed) - these are processes with positive feedback. And vice versa - correctly designed processes that allow the system to function the necessary time (laid down during design) is a direct example of negative (corrective) feedback. A project that is being run somehow and somehow managed, has positive feedback or a disturbed negative feedback - it will not be completed on time, with a given cost, with a given quality (individually or all at once). Repair in the house, when constantly there are opinions from the outside, changing your original plan - exactly the same example. A restaurant with missing / broken negative feedback will go bankrupt because the quality of his dishes will constantly go further and further from the standard (in any direction). A country managed with broken or no feedback from the people at all is doomed, like a project or repair managed in the same way.

    At the same time, repairing or creating the necessary feedback from scratch can often solve 90% of control problems. In projects, this is often communication. In the development of systems - the correct design. In society - all the same communications and processes that are subject to the control of society.

    Unfortunately, many people are not used to reasoning in such categories. They are trying to come up with “crutches” for improperly designed processes that support the process / system from different angles. But such “crutches” - in 90% of cases are not a feedback repair (creating a missing connection). These are crutches, backups. The result of using such “innovations” is always predictable, even with a fairly high share of accuracy in time, not to mention the 100% probability of a collapse, which they tried to prevent with “crutches”.

    Thanks for attention. Feel free to comment.
