What is negative feedback in the workplace?

What is meant by negative feedback?

A negative feedback loop is a closed loop feedback mechanism that causes a change in the state of the system.

In the case of a closed loop feedback mechanism, a change in the state of the system will cause a change in the output. A negative feedback loop can be created using voltage divider or resistive divider (using two resistors in parallel), capacitors (with one capacitor and one resistor), inductors (using two coils in series), and operational amplifiers. The term "negative" is simply referring to the direction of the change in state (eg. An increase in voltage means the signal is being "clamped").

For example, an operational amplifier with a resistive input and a fixed voltage source for the non-inverting input will have a negative feedback loop.

What is an example of negative feedback in a system?

I'm not completely sure what you mean by a "negative feedback", but I think one example would be something like this: Consider a thermostat.

In many cases, the temperature of a home/office is maintained via a simple feedback loop that uses some sort of sensor to detect the ambient temperature of the home/office, then adjusts the heating and cooling so as to maintain the ambient temperature. But thermostat doesn't just keep the temperature in a steady state, it also controls how quickly the system is switched between heating and cooling. The faster the switching, the more heat is added or removed from the building.

If thermostat isn't working properly, this can cause some issues. For instance, a slow switching speed will allow a room to become too cold and a fast switching speed will allow a room to get too hot. This can happen whether the problem with thermostat is due to a malfunctioning component or it's malfunctioning as designed.

It's usually important that the switching between heating and cooling happens fast, otherwise you can end up with a dangerous thermal buildup or over-cooling the building. But if the switching between heating and cooling isn't fast enough, then you can also have other problems. A well-designed thermostat will be able to switch at a fast enough rate to avoid problems, but it's the duty of a maintenance person to ensure that it does.

Negative feedback in control systems can occur when the setpoint has been exceeded. The system needs to work harder to bring it back to normal. So at some point a setpoint is exceeded and there are some type of negative feedback. A good example of this is when a car is driving too close to another car. The system knows something is going on and works to slow down the car.

Here is a video example of negative feedback for the airspeed controller used in aircraft.

What is negative feedback in the workplace?

I have been asked to do an essay in which I will discuss two ideas.

In the first, "negative feedback" is an employee-focused policy. One of the company's goals is to provide each employee with negative feedback for every bad work/life balance. It's a way of showing appreciation and acknowledging that employees are people. The theory goes that they'll appreciate this type of encouragement, and perform better as a result.

In the second idea, it's not a company-wide policy; it's optional. Sometimes people prefer positive feedback to negative feedback. So why, when a situation requires negative feedback in the workplace, should they not make that choice?

What do you think: which option is more effective, when employees ask for it? As a side point, if your employer is trying to be "treats them like adults and respects them as human beings", then you're already a little late with this request. I would suspect you are asking because of your personal preference of receiving positive feedback or having to listen to one of those old 'he said' "how about you quit crying?" 'she said' ones.

If a person has to ask, then they've been denied that opportunity for too long. The problem is, everyone will answer that positive feedback is easier to give, but there is so much truth to that. For a person to actually be happy about being criticized, they need to be in a position to decide if the criticism is true or not. If they weren't doing so well before, there's a good chance they are not qualified to handle negative feedback; on the other hand, most people, by nature of their personality, have a pretty negative sense of their personal failings anyway, so giving them the opportunity to self-critique won't mean much. People can also be quick to accept things as correct, when they know they aren't. If an employee has an emotional block about being criticized, they won't benefit from negative feedback as it cannot reach them.

So, if you want to put someone in a position to grow, you don't force them into a negative feedback situation, where they will fail to grow. You leave them in a positive feedback situation and see what happens. If they succeed, then you praise them.
