Chapter 1: Information System and You
(Computer Based) Information System
Information System (IS): A group of components that interact to produce information
Five-Component Framework: Present in every IS
o Hardware: Computer, storage disk, keyboard, and monitor
o Software: Programs or applications
o Data: Words, sentences, and paragraphs that are reported
o Procedures: Methods of the hardware in dealing with software and software in dealing with data
o People: Human beings (or networks); the most critical part of an information system
Management Information Systems (MIS)
Development of Information Systems
o What will the system do?
o What is its purpose and what will it enable us to do?
o Will it aid us in achieving our goal?
Use of Information Systems
o Have an active role in the MIS to ensure that the system meets our needs
o Understand how the system evolves
o Consider users’ needs during development of the system
o Learn how to use the systems, especially: security, back-up, and recovery
Achieving Business Goals and Objectives
o People perform the activities of a business: designing, producing, marketing, and accounting
o MIS empowers users and businesses to reach their goals
o IS must be developed and used for the right reasons (is it worth the investment?)
Information System (IS) VS. Information Technology (IT)
IT: Methods, inventions, standards, and products (raw technology)
o Must be embedded into an IS that it becomes useful
o This is especially the case in that only IS and not IS includes a human interaction with the technology
o EX: A person creating a webpage is using IT, but IS takes the bigger share of completing the project
Importance of IS
Information and Communications Technology (ICT) sector includes
o Sector that provides products and services to other industries such as :
Retail & manufacturing & insurance & banking
o Many companies in the ICT are reporting increased number of jobs and above average earnings Today, everybody uses various basic information systems including e-mail, accessing web-pages, using Word /
PowerPoint / Excel software and processors, and instant-messaging.
To have a competitive advantage, however:
o Consider IS and IT in any issues
o Think creatively about problems, challenges, and opportunities (to be productive, be innovative)
o Create innovative applications using emerging technologies (or apply them to your business needs)
o Expand knowledge on project management software, business graphics, and collaborative systems
o ICTC Report writes that additional skills are necessary:
Specific technology and industry experience
Satisfactory communications and other business skills
What is the Shape of Things to Come?
How will IT and IS affect the way we live and work?
o ―The complexity for minimum component cost has increased at a rate of roughly a factor of two per
year…Certainly over the short term this rate can be expected to continue, if not to increase….‖
o Published in 1965 by Gordon Moore (Co-Founder of Intel)
o Despite difficulty in predicting the future of technology due to new innovation (iPo
