Conclusions


Ç™Ç±ÇÃÉsÉNÉ`ÉÉÇ¾å©ÇÈÇžÇ½Ç…ÇÕïKóvÇ-Ç� The outside changes have to be perceived.The danger is that executive will become contemptuous of information that cannot be reduced to computer logic and language. The computer information may thus shut out access to reality.Where communication is perception, information is logic.
