Business Intelligence and
Decision Support
A century ago, John Wanamaker, FATHER OF MODERN
ADVERTISING, said
Half the money I spend on advertising is wasted;
the trouble is I don't know which half.

BI, data mining, and DSSs are used to
minimize uncertainty (the reverse of
intelligence) and to be able to make
faster, smarter decisions—often in realtime.
When managers and workers have the
intelligence they need to respond correctly
and quickly to opportunities, threats, &
mistakes, they and their companies
significantly outperform those that don’t.

11.1 Business Intelligence (BI) for Profits &
Nonprofits
BI refers to a collection of ISs and technologies that support
managerial decision making or operational control by
providing information on internal and external operations.
– It’s tough to fully understand BI because BI apps are not
stand-alone systems nor do they support a specific
objective, as do supply chain management (SCM) or
customer relationship management (CRM).
– Visualization tools including dashboards &
mashups are the user-interfaces that help
people understand the numbers.

BI Cases
• WildTrack (wildtrack.org/), monitors and verifies
endangered rhinos in Africa
• United Way (unitedway.org/), monitors
fundraising campaigns and generates reliable
reports
Figure 11.3 Endangered
black rhinoceroses are
tracked using BI
• Jamba Juice, (jambajuice.com/), monitors
customers’ preferences and captures data for
fast, reliable P&L and financial reporting

Predictive Analytics
Branch of data mining that focuses on forecasting trends (e.g.,
regression analysis) and estimating probabilities of future
events

analytics. (Data from

Event-Driven Alerts
Event-driven alerts are real-time alerts or warnings
that are broadcast when a predefined event occurs.
Figure 11.6 (in textbook) shows the processing that
takes place when an unusually large deposit occurs
For a credit card company, a customer's sudden payoff
of the entire balance might trigger a business rule that
creates an alert because the payoff could be a signal
that the customer is planning to cancel the card.
– E.g., There could be an intervention, such as a low
interest rate offer, to reduce losing the customer.

Data Visualization
Purpose of BI is to gain insight from data for the purpose of
taking action

BI Saves Lives of Wounded Soldiers from Battlefield to
Treatment
When soldiers are wounded in battle, the military needs to be
able to quickly diagnose their condition and provide medical
transport. TRAC2ES tracks & coordinates patient information
throughout the U.S. military’s worldwide network of
healthcare facilities.

architecture of TRAC2ES to
calculate the best transport
method & the most appropriate
medical center for treatment

11.3 Data, Text, and Web Mining
• Data mining is a process that uses statistical, mathematical,
artificial intelligence, and machine-learning techniques to
extract and identify useful information from large databases
• Text from documents, e-communications, and e-commerce
activities can be mined. Text needs to be codified, typically with
XML (eXtensible Markup Language), and extracted so that
predictive data mining tools can be used to generate real value
• Web mining, or Web-content mining, is used to understand
customer behavior, evaluate a Web site's effectiveness, and
quantify the success of a marketing campaign
11-9
Data Mining Apps
•
Retailing and sales. Predicting sales, determining correct inventory levels
and distribution schedules among outlets, and loss prevention.
•
Banking. Forecasting levels of bad loans and fraudulent credit card use
and which kinds of customers will best respond to new loan offers.
•
Manufacturing and production. Predicting machinery failures; finding
key factors that control optimization of manufacturing capacity.
•
Healthcare. Developing better insights on symptoms and their causes
and how to provide proper treatments.
•
Broadcasting. Predicting which programs are best to air during prime
time
•
Marketing. Classifying customer demographics that can be used to
predict which customers will respond to a mailing or Internet banners or
buy a particular product

Types of decisions
Structured decisions are routine and repetitive
problems for which standard solutions exist.
Unstructured decisions involve a lot of uncertainty for
which there are no definitive or clear-cut solutions.
Semistructured decisions fall between the polar
positions.
