Cybernetic Systems

  Necessity is the mother of invention. Many sophisticated systems have been developed under the circumstances which were eventually used for the market or societal needs. Some of those systems suffer from what is known as brittleness, meaning that some of those are designed to work on specific scenarios but not in many others.
   One of the critical issues regardless IS and healthcare is that through intranet server technology the patients' data is entered, verified, stored once and at-once and is now accessible from all the hospital who participate in the IS network. Due to possibility of failure multiple backups are recommended in IS.
   A Cybernetic system (stems from the Greek kybernētēs, steersman, governor, pilot, or rudder — the same root as government) is a self-monitoring, self-regulating complex system that uses feedback and control.
Feedback consists of data about the performance of the system and control involves monitoring and evaluating the feedback to determine whether a system is moving towards the achievement of its goal, then making requisite changes.
   Cybernetic systems are all around us. An every day example would be while driving on a road with curves:
-Input: visual images
-Processing: steering wheel; gas pedal; brakes
-Outpout: moving along the road
-Feedback: deviating out of your lane of traffic
-Control: turning the steering wheel.

A business may be viewed as a Cybernetic System:

 A Business is an open system that interacts with other systems in the environment. It is also an adaptive system that it can change itself or its environment in order to survive.

Major components of an information system: people, hardware, software, data and networks. These components perform input, processing, output, storage and control activities. 

Information systems are cybernetic systems themselves
