It is not the system manager of the information system and the like, the system service user of the enterprise manager and business section etc. direct operates the computer actively, participates in the construction of the system, uses in management and business.
When as it utilizes the computer, "expedient in order to achieve purpose" the utilization form that user itself possesses that purpose, operates the computer directly, was supposed for a long time as the "ideal image".
The early computer being very expensive, the user (the programmer) bringing the program which records to the hollerith card to the computer center which is far far requested processing, waited many days and received the result. Vis-a-vis such circumstance, J C R ??????? (Joseph Carl Robnett Licklider), the concept of conversational computing in the dissertation, "Man-Computer Symbiosis" was shown, importance of interaction of the user and the computer was explained.
When there is also effort of ???????, enters intothe sixties and the time-sharingsystem is utilized, simultaneous utilization of the computer possible ?, reaches the point where it can access the computer the user to interactive.
The computer user of these times was the programmer and the computer researcher, but from the seventies latter half which business utilization of the computer starts activating betting on the eighties, there was also appearance of the mini computer andthe office computer and DSS (thedecision support system) lecture etc., high-level decision making person such as manager direct and interactive, utilizing ad hoc insisted the computer for business analysis. Furthermore utilization of the user was made prerequisite from beginning the personal computer which appears in the eighties (PC) in. However, PC with system of the IBM PC compatible machine which loads DOS/MS-DOS, CUI is prerequisite, it did not go to the place that it can utilize everyone.
When it enters into the nineties, the business utilization of PC spread, but as for PC introduction at enterprise becoming independent with the information system, there was a tendency which business section does with budget and judgement of the self. The word, end user computing such business section (end user section) concerning the introduction of computers utilization of main leadership was used.
Is located in 1994 as one of national qualification "information processing technicians" was startedthe "systemadministrator" as the talent who promotes end user computing, but, the role there being an end user section, when it is the system operation patsy, simultaneously, is made mediation part of professional engineer such as information system section and system integrator. Here, it has become prerequisite for end user side to participate positively in regard to the demand and specification for the system.
The end user computing which the business section which knows business itself well directs when promoting the IT conversion which matches to business on the basis of quick decision making is the method which is superior, but it is indispensablefor the information literacy whichis sufficient for business section itself to have been provided. In addition, "specific section projects", "the basic system and the system which does not have consistency are made", "optimization at company-wide level is not assured", because and so on there is a possibility the harmful influence coming out,as not lostIT ?????, it is necessary to consider.
