CHAPTER 3
EVALUATING INFORMATION
![Page 22: MIS 213 - csbapp.uncw.edu](https://reader031.vdocuments.site/reader031/viewer/2022012014/6159001313e88d4f386daf2c/html5/thumbnails/22.jpg)
THE BUSINESS BENEFITS OF HIGH-
QUALITY INFORMATION
Information is everywhere in an organization
Employees must be able to obtain and
analyze information to make decisions
Successfully analyzing information can
provide tremendous insight into how an organization is performing
![Page 23: MIS 213 - csbapp.uncw.edu](https://reader031.vdocuments.site/reader031/viewer/2022012014/6159001313e88d4f386daf2c/html5/thumbnails/23.jpg)
MANAGERS VALUE
INFORMATION…
To improve decision making
To justify decisions
To verify previously-acquired information
To “play it safe” by making sure they do not miss any
relevant information
In the belief that the information may be useful later

INFORMATION TIMELINESS
Timeliness is an aspect of information
that depends on the situation
Real-time information – Immediate, up-
to-date information
Real-time system – Provides real-time
information in response to requests
![Page 25: MIS 213 - csbapp.uncw.edu](https://reader031.vdocuments.site/reader031/viewer/2022012014/6159001313e88d4f386daf2c/html5/thumbnails/25.jpg)
INFORMATION QUALITY
Business decisions are only as good as
the quality of the information used to
make the decisions
![Page 26: MIS 213 - csbapp.uncw.edu](https://reader031.vdocuments.site/reader031/viewer/2022012014/6159001313e88d4f386daf2c/html5/thumbnails/26.jpg)

UNDERSTANDING THE COSTS OF
USING LOW-QUALITY INFORMATION
The four primary sources of low quality
information include
1. Customers intentionally enter inaccurate information to protect their privacy
2. Different entry standards and formats
3. Operators enter abbreviated or
erroneous information by accident or to
save time
4. Third party and external information contains inconsistencies, inaccuracies,
and errors
![Page 28: MIS 213 - csbapp.uncw.edu](https://reader031.vdocuments.site/reader031/viewer/2022012014/6159001313e88d4f386daf2c/html5/thumbnails/28.jpg)
UNDERSTANDING THE BENEFITS OF
GOOD INFORMATION
High quality information can
significantly improve the chances of
making a good decision
Good decisions can directly impact
an organization's bottom line
![Page 29: MIS 213 - csbapp.uncw.edu](https://reader031.vdocuments.site/reader031/viewer/2022012014/6159001313e88d4f386daf2c/html5/thumbnails/29.jpg)
INFORMATION QUALITY VS. COSTS
Context of information quality matters
For example, stock price information is often
delayed for free information services; this is
acceptable to casual investors but
devastating for a day trader
High quality information, however, is
costly
The goal is information that is of sufficient
quality to carry out tasks effectively. Bélanger, Van
