IT PROFESSIONALS
An information system is a collection of resources working together in a coordinated fashion to store, process and provide data for end-users. The term information systems (IS) is used interchangeably with the term information technology (IT). Five main resources of an information system are: 1. 2. 3. 4. 5. People Hardware Software Data Networks An automatic teller machine (ATM) is a good example of a system that is efficient, effective and competitive. ATM’s have transformed the banking industry.
Benefits of information technology are: Speed Accuracy Consistency Availability Innovation
Opportunities of information technology are: Operational – more efficient; IT increases speed and accuracy. Tactical – more effective; IT provides consistency and availability. Strategic – more competitive; IT transforms the organization through innovation.
