CONTROL AS A FEED BACK SYSTEM
Many systems control themselves through information feedback, which shows
deviations from standards. A simple feedback system can be shown by figure.

Any attempt to control without plan is meaningless. Plans furnish the standards of
control. Information feedback is like the house thermostat when the house
temperature falls below the preset level, an electric message is sent to the heating
system, which is then activated. When the temperature increases and reaches the (setlevel)
another message shuts off the heater. This continual measurement and training
on and off the heater keeps the house at the desired temperature. A similar process
activates the air-exceed the preset level, the air conditioning system cool the house to the desired temperature. Like wise, in human being body, a number of feedback
systems control temperature, blood pressure and another conditions.
Management control as a feedback system is similar to the system of feedback in
house thermostat. This can be shown by diagram.

CONTROL AS FEEDBACK SYSTEM
This system places control in more complex way. These systems including steps,
establishing standards, measuring performance and correcting for deviations.
Managers do measure performance, establish standards and identify deviations, they
must then to make the necessary corrective action.
REAL TIME INFORMATION & CONTROL

FEEDBACK FORWARD CONTROL
Feed forward control is system that attempts to identify future deviations. This
control shows the deficiency of historical data. For example one of the difficulties
with such historical data is that they tell business managers is November that they lost
money in October or even September because of some thing that was don in July. At
this late time such information is only a interesting historical fact. Feed forward
control is manager have been so dependent for purposes of control on accounting and
statistical data.
