ISQS Exam 1 (Texas Tech, Delgadillo)
Characteristics of good information - ✔️✔️Accurate, complete, economical, flexible,
reliable, relevant, simple, timely, verifiable.
Data - ✔️✔️Raw facts
Information - ✔️✔️The meaningful interpretation of data that enables us to make
decisions.
What makes data = information? - ✔️✔️It's usefulness!
System - ✔️✔️An organized collection of interrelated parts that work together to
achieve a common purpose.
What do systems have? - ✔️✔️Inputs,
procession mechanism,
outputs,
feedback,
control.
Subsystem - ✔️✔️(Of a system) University -> Business school -> Marketing.
Simple vs. Complex System - ✔️✔️Simple- Very few elements & components,
relationship is simple.
Complex- A system filled with many simple systems.
A collection of simple systems is better than one, large complex system.
Open vs. Closed System - ✔️✔️Open- Everyone can use, don't have to have control of
market (interact with other systems)
Closed- Exclusive, not adoptable; only if you have control of market (no interaction)
Information Technology - ✔️✔️Refers to the method, techniques and tools that are
used as means to bring about computer-based information systems.
Information System - ✔️✔️Is a set of interrelated components
that collect (input), manipulate and
store (processing), and disseminate
, (output) data and information as well
as a feedback mechanism.
What is input and processing? - ✔️✔️Input - is the activity of capturing
and gathering raw data.
Processing - involves converting or
transforming raw data into useful
output.
Output - ✔️✔️Involves producing useful
information, usually in the form of
documents and reports.
Feedback - ✔️✔️Is output that is used to make
adjustments or changes to input or
processing activities.
Control - ✔️✔️Involves monitoring and
evaluating feedback.
Computer Based Information System - ✔️✔️is an Information System that uses
computer systems, devices, and technology.
Computer-Based IS Components?! - ✔️✔️Hardware, Database, Networks, Procedures
***Software, People = KEY!!!!***
Comparative Advantage - ✔️✔️Is a significant and long-term benefit to a
company in relation to the competition (innovative thinking, IDEAS!!)
Competing with Information
Technology - ✔️✔️Competitive value of IT lies mostly in the
capability of software and of people and the
value of information a business acquires and
uses.
Strategic Information Systems - ✔️✔️Any kind of IS that uses IT to gain competitive
advantage (or sometimes reduce competitive advantage).
Major types of IS - ✔️✔️- DSS - decisions (what if analysis) - Strategic, Upper
- MIS - reporting - Tactical, Middle
- TPS - transactions - Operational, Lower
Transaction Processing System - ✔️✔️Is an organized collection of people,
