1. Feed-forward is a term describing a kind of system which reacts to changes in its environment, usually to maintain some desired state of the system. A system which exhibits feed-forward behavior responds to a measured disturbance in a pre-defined way - in contrast with a feedback system.
2. This is a control technique that can be measured but not controlled. The disturbance is measured and fed forward to an earlier part of the control loop so that corrective action can be initiated in advance of the disturbance having an adverse effect on the system response.

Feed Forward control is mechanism within some control systems in which information is sent ahead in time to prepare a part of a control system.

Control environment, risk assessment, control activities (procedures), communication, and monitoring
An organization establishes a system of internal control to help it manage many of the risks it faces, such risks are classified as follows:- * Inherent Risk * Control Risk * Detection Risk Establishing an internal control is the responsibility of the management, the elements (components) of internal control framework are the following:- * Control environment * Risk Assessment * Control Activities * Information & Communication * Monitoring
the purpose of a control system is to manage

Feedforward.
One major advantage of feedforward controls is that it prevents large disturbances in your output. A disadvantage is that it may not account for all potential disturbances in the input, leading to large disturbances in the output.
Feedforward is a preparatory control. EX. Smelling food leads to salivation and production of stomach acid in preparation of food. OR Starting to exercise increases heart rate and breathing rate in preparation of running low on oxygen for muscles. Feedback is a control mechanism where the product of the end mechanism either enhances or inhibits the start of the mechanism Positive feedback enhances Negative feedback inhibits
In Control function of Management,Critical control point (CCP) is a point, step or procedure at which controls can be applied to the system (feedback or feedforward) and a disturbance can be prevented, eliminated or reduced to acceptable (critical) levels.

Sometimes feedback controls are called preliminary controls, they are accomplished before a work activity begins. They make sure that proper directions are set and that the right resources are available to accomplish them
Feedforward is anticipatory in nature. It is your body preparing for something before it occurs. The classic example is smelling something delicious. Even though you haven't eaten anything yet, your mouth begins to salivate, excreting digestive enzymes, and your stomach begins to produce acid. This way your body doesn't have to quickly react. Another example is exercise. Your heart rate and breathing rate increase long before your muscles begin to run low on oxygen. You can almost think of feedforward as a type of preventative measure.
It begins with the establishment of clear standards of performance, involves a comparison of performance to those standards, takes corrective actions, if needed, to repair performance deficiencies; is a dynamic, cybernetic process, and uses three basic methods-- feedback control, concurrent control, feedforward control.

Humans think because they have a brain which allows feedforward and look-ahead planning.
