COB 204 JMU Test #1
Critical Non-Routine Skills that an Intro to MIS Course Can Help you Learn - ✔️✔️-
Abstract reasoning
- Systems Thinking
- Collaboration
- Experimentation
Characteristics of the Five Components - ✔️✔️•Most Important Component - YOU!
-Your cognitive skills determine quality of your thinking, ability to conceive information
from data.
-You add value to information and information systems.
•Only humans produce information.
•All components must work together.
Information Technology (IT) - ✔️✔️-The products, methods, inventions, and standards
used for the purpose of producing information
- components = Hardware + Software + Data
Information System (IS) - ✔️✔️components = Hardware + Software + Data +
Procedures + People
Management information systems (MIS) - ✔️✔️-The management and use of
information systems that help organizations achieve their strategies
Difference Between IT and IS - ✔️✔️IS = IT + Procedures + People
The IS Five-Component Model - ✔️✔️
Defining Information - ✔️✔️Knowledge derived from data.
Characteristics of Data - ✔️✔️- accurate
- timely
- relevant
- just sufficient
- worth its cost
Goldilocks Principle - ✔️✔️•Right information to the
•Right people at the
•Right time
•For a reasonable cost
The Digital Revolution - ✔️✔️-From mechanical/analog devices to digital devices.
, Information Age - ✔️✔️-Production, distribution, control of information primary
economic drivers.
Five Technology "Laws" - ✔️✔️-Bell's, Moore's, Metcalfe's, Neilsen's, & Kryder's
Bell's Law - ✔️✔️- Today's highly successful business could be bankrupt quickly
because technology changed and it didn't.
Business professionals need to... - ✔️✔️-Take active role to ensure systems meet their
needs.
-Understand how information systems (IS) are constructed.
-Consider users' needs during development.
-Learn how to use IS.
-Don't forget security and backups.
- "A new computer class forms roughly each decade establishing a new industry."
Implications: Digital devices will evolve so quickly that they will enable new platforms,
programming environments, industries, networks, and information systems every 10
years
Moore's Law - ✔️✔️"The number of transistors per square inch on an integrated chip
doubles every 18 months."
Implications: Computers are getting exponentially faster.
The cost of data processing is approaching zero.
Metcalfe's Law - ✔️✔️"The value of a network is equal to the square of the number of
users connected to it."
Implications: More digital devices are being connected together.
The value of digital and social networks is increasing exponentially.
Network Value = Users^2
Nielsen's Law - ✔️✔️"Network connection speeds for high-end users will increase by
50 percent per year."
Implications: Network speed (throughput) is increasing. Higher speeds enable new
products, platforms, and companies.
