Document Summary
Purpose: to provide accurate, timely and useful information. Each element must be present and all of the elements must work together. Information system (is) = it plus procedures and people that produce and utilize information. It = hardware + software + data. Do not try to buy an information system; you can not do it. Buy or lease hardware, license programs and databases, even obtain predesigned procedures. Ultimately, people execute those procedures to empoy that new it. Any new system requires training tasks, overcoming employees resistance to change, and managing employees as they utilize new system. Information is data shaped into meaningful form. Input: captures raw data from organizations or external environment. Processing : converts raw data into meaningful form. Output: transfers processed information to people or activities that use it. Advanced information systems also incorporate one additional functionality: Feedback - output returned to appropriate members of organization to help evaluate or correct input stage.
