Chapter 1: Introduction to Information Systems
Information Technology (IT)-Any computer based tool that people use to work with
information and to support the information and information-processing needs of an
organization
Information Systems (IS)-Collects, processes, stores, analyzes, and disseminates
information for a specific purpose
1.1 Why Should I study information systems?
Informed User-A person knowledgeable about information systems and information
technology
Informed users get more value from whatever technologies they use
Many benefits from being an informed user of IT:
(1) You understand what’s “behind” the IT applications
(2) You can enhance the quality of your organizations IT applications
(3) You can recommend-or even help-select the IT applications your organizations will use
(4) You will understand how using IT can improve your organizations teamwork and
performance
IT Offers Career Opportunities
Information systems field includes the people in the organizations who designs and build
information systems, the people who use those systems, and the people responsible for
managing those systems
IT Manages Information Resources
Managing information systems in modern organizations is a difficult task. Several factors
contribute to this complexity
(1) Information systems have enormous strategic value to organizations
(2) Very expensive to acquire, operate and maintain
(3) Difficulty in managing information systems is the evaluation of the Management
Information Systems (MIS) function within the organization
End user computing-Computers are located in all departments, and almost all employees
use computers in their work. Two components:
(1) End-user data entry, reporting and inquiry (AKA users)
(2) End-user development-Users develop usable systems (spreadsheets, programs , etc.)
As a result of these developments, responsibility for managing information resources is now
divided between the MIS department and the users. Division depends on several factors:
Size and nature or organization
Amount and type of IT resources
Organizations attitudes toward computing
Attitude of top management toward computing
Maturity level of technology
Amount and nature of outsourced IT work
Countries in which the company operates
