Feedback Loop:
What is feedback loop?
The feedback loop can be change in system by enhances or buffer. Thus, the idea of feedback loop is the valuable of information. It is describes as the stages of information movies through from it's initial generation in an organization to improve the products and services that client needs. Therefore, the key of improving the products and services is to find a way of gather all the information and lead it into a correct way.
However, there are 8 phase of feedback loop that I found in http://spmresourcecentre.net/ which are:
1. Information collection - Data is gathered on a formal and informal basis.
2. Information consolidation - Raw data is turned into a usable form.
3. Analysis - Information is formally assessed in terms of client and institutional needs, and forms the basis for recommendations to satisfy those needs.
4. Reporting - The analysis is summarized in written and/or verbal form for ease of decision-making.
5. Decision-making - Decisions are made, based on data and recommendations from the reporting phase.
6. Delegation - After a decision is made, the person responsible for implementing it must be fully aware of all requirements.
7. Communication - All staff involved in implementing changes must be fully informed of all issues and procedures.
8. Implementation - Changes to products or services are pilot-tested and based on this a decision for implementation is made.
To follow the 8 phase of feedback loop is to valuable the resources that we found for a better presentative or effectively for our client.

The article of Maggie McGarry of discussing the theory of Wiener's Cybernetics theory that I found it is quite useful and makes me understandable about the general idea of what is Cybernetics. In the following I would like to note down that what I have understand about Cybernetics from Professor Maggie McGarry.
The word is came from the Greek 'Kubernetes' which means the art of steering. It has becomes 'Governor' in Latin. Therefore, what is cybernetics?
The definition of cybernetics that I found in Dictionary.com that it's to study of human control function and designed to replace the mechanical and electronic systems. It is involving the application of statistical mechanics for exchanging the information with engineering.
According to Maggie McGarry from the University of Colorado at Boulder in 2008. She has discussed the theory of Norbert Wiener who has published his book Cybernetics in 1948. He has developed a theory of communication and control which he has compared there is no different of the function of communication between humans and machines by completed a task. He suggested that humans have the information processing and remaining the desire to control our environment and also the around of environment just like operate in machine-like manner.
Maggie noted that Wiener has mentioned the thesis in his article, Cybernetics In History that :
... society can only be understood through a study of the messages and communication facilities which belong to it; and that in the future development of these messages and communication facilities, messages between man and machines, between machines and man, and between machine and machine, are destined to play an ever increasing part.
Thus, the basic function of communication in the Wiener's theory is spreading the knowledge and information to make the life of human better. He has noted the goal of human communication to become familiarized. Therefore, the purpose of cybernetics is to enable the human attack the problem of control and communication by developing the language and techniques.
However, Wiener has insert the idea of entropy in his theory to organized or to balance up the system. Therefore, 'information' such as sent or received is essential to maintain organization and structure. In the Human Communication Theory of Maggie, she has noted that 'Wiener refers to simple machines as closed, clockwork-based apparatuses that do not require any communication with the outside world. They repeat their designated task in a pattern, regardless of any factors in their surrounding environment influencing them one way or another.' Therefore she gives an example for what Wiener refers to; the refrigerator which could preserve energy automatically without given any information that the senses of feedback from environment and adapt their behavior according in order to function within its system.
Another aspect in Wiener's theory is the environment as a part of the feedback that Wiener defines the feedback as it is better to control the machine on basis of its actual performance rather than expected performance.
