text: how information and communication technology affects functions of business and how it affects employabilit? terms should be used to answer:- production  marketing  accounting human resources since the topic is so wide ,, we stick to only one argument ,,    the  _talent , _skill and the _expert knowledge that companies need to tie and  link  the departmental   informations is a challenge and a cost center.  people are used to , and trained to work by =information , but machines and technology record and transmit   only  =data , maybe =numbers.  there is no fixed protocol on how you shall derive =information from the =data presented.  companies also   struggle with documentation , especially procedural.    so , the cumputerisation not only costs money , but it cost human downtime , even waiting for the   departmental heads to agree on "protocol".  there is a high degree of uncertainty on the ground.    and every departmental head has his own oppinion on what a computer is ,, but never the correct one , and is   not comfortable making a technical decision ,, as simple as a "safety" overide , whether to have or not.   current age , we have simply overloaded the human brain to handle the "manufactured" reality.    also , neither is the computer geek comfortable in the anlogue , in areas of technology rheo (plastics) ,   material , machanical , or balancing the system q , or machine q , machine tuning in general , or anything   that considers the continuum. so , they won't caliberate the ph meters or the  set-up the strain gauge either , therefore they cannot caliberate !!  say , what you like , they are not comfortable with the legal aspects of caliberation.  to say that if the computer is showing a pressure drop runtime , what could it be.  the obd ecu (computer) in the car is an example.     * information and communication technology has made a world where neither the geek nor us know what is happening.
