DECISION MAKING
• Reasons for the growth of decision-making
information systems
– People need to analyze large amounts of
information
– People must make decisions quickly
– People must apply sophisticated analysis
techniques, such as modeling and forecasting, to
make good decisions
– People must protect the corporate asset of
organizational information
DECISION MAKING
• Model – a simplified representation or
abstraction of reality
• IT systems in
an enterprise
TRANSACTION PROCESSING
SYSTEMS
• Moving up through the organizational pyramid users move
from requiring transactional information to analytical
information
Fine
Coarse
TRANSACTION PROCESSING
SYSTEMS
• Transaction processing system (TPS) - the basic business
system that serves the operational level (analysts) in an
organization
• Online transaction processing (OLTP) – the capturing of
transaction and event information using technology to (1)
process the information according to defined business rules,
(2) store the information, (3) update existing information to
reflect the new information
• Online analytical processing (OLAP) – the manipulation of
information to create business intelligence in support of
strategic decision making
• Cf. Online analytical mining (OLAM)
DECISION SUPPORT SYSTEMS
• Decision support system (DSS) – models information to
support managers and business professionals during the
decision-making process
• Three quantitative models used by DSSs include:
1. Sensitivity analysis – the study of the impact that
changes in one (or more) parts of the model have on
other parts of the model
2. What-if analysis – checks the impact of a change in
an assumption on the proposed solution
3. Goal-seeking analysis – finds the inputs necessary
to achieve a goal such as a desired level of output
DECISION SUPPORT SYSTEMS
• What-if analysis
DECISION SUPPORT SYSTEMS
• Goal-seeking analysis
DECISION SUPPORT SYSTEMS
• Interaction between a TPS and a DSS
EXECUTIVE INFORMATION SYSTEMS
•
Executive information system (EIS) – a
specialized DSS that supports senior level
executives within the organization
•
Most EISs offering the following capabilities:
– Consolidation – involves the aggregation of
information and features simple roll-ups to complex
groupings of interrelated information
– Drill-down – enables users to get details, and
details of details, of information
– Slice-and-dice – looks at information from different
perspectives
EXECUTIVE INFORMATION SYSTEMS
• Interaction between a TPS and an EIS
Digital Dashboards
• Digital dashboard – integrates information
from multiple components and presents it in a
unified display

Chapter Overview
• Decision-enabling, problem-solving, and
opportunity-seizing systems
What is Business Intelligence?
Business Intelligence enables the
business to make even more intelligent,
faster decision based on DSS.

Artificial Intelligence (AI)
• Intelligent system – various commercial
applications of artificial intelligence
• Artificial intelligence (AI) – simulates
human intelligence such as the ability to
reason and learn
Artificial Intelligence (AI)
• The ultimate goal of AI is the ability to build a
system that can mimic human intelligence
Artificial Intelligence (AI)
•
Four most common categories of AI include:
1. Expert system – computerized advisory
programs that imitate the reasoning processes
of experts in solving difficult problems
2. Neural Network – attempts to emulate the way
the human brain works
– Fuzzy logic – a mathematical method of handling
imprecise or subjective information
Artificial Intelligence (AI)
• Four most common categories of AI include:
3. Genetic algorithm – an artificial intelligent
system that mimics the evolutionary, survival-ofthe-fittest process to generate increasingly
better solutions to a problem
4. Intelligent agent – special-purposed
knowledge-based information system that
accomplishes specific tasks on behalf of its
users
CPU – Content, Performance, Usability
• Content
– The business determines the “what”, BI enables the “how”
• Performance
– Minimize report creation and collection times (near zero)
• Usability
– Delivery Method Push vs Pull
– Medium  Excel, PDF, Dashboard, Cube, Mobile Device
– Enhance Digestion  “A-ha” is readily apparent, fewer clicks
– Tell a Story  Trend, Context, Related Metrics, Multiple Views

Why is Business Intelligence So Important?

Making Business
Decisions is a Balance
In the absence of data, business decisions are often made by the HiPPO.
With Business Intelligence, we can get data to you in a timely manner.
The July 2010 Forrester report “Technology
Trends That Retail CIOs Must Tap to Drive
Growth” identified the following technologies
that retail CIOs should be considering as
part of an overall architecture strategy:
Mobile
Social Computing
Cloud
Supply Chain
Micropayments
Business Intelligence/Analytics
Major BI Trends
• Mobile
• Cloud
• Social Media
• Advanced Analytics

1. Predictive Analytics
2. Visualization/Dashboards
3. Master Data Management
4. The Cloud
5. Analytic Databases
6. Mobile BI
7. Open Source
8. Text Analytics
BI Today vs Tomorrow
• “BI today is like reading the newspaper”
– BI reporting tool on top of a data warehouse
that loads nightly and produces historical
reporting
• BI tomorrow will focus more on real-time
events and predicting tomorrow’s
headlines
Who does use BI?
only Business firm?
• Essential to the success of companies in a wide range of industries,
and more famously essential to the success of professional sports
teams such as the Boston Red Sox, Oakland A’s and New England
Patriots.
• With an analytical approach, the Patriots managed to win the Super
Bowl three times in four years. The team uses data and analytical
models extensively, both on and off the field. In-depth analytics help
the team select players and stay below the NFL salary cap. Patriots
coaches and players are renowned for their extensive study of
game film and statistics.
• Off the field, the team uses detailed analytics to assess and
improve the "total fan experience." At every home game, for
example, 20 to 25 people have specific assignments to make
quantitative measurements of the stadium food, parking, personnel,
bathroom cleanliness and other factors.

The Power of Visualization
Even though a picture is “worth a thousand
words,” we have to be very careful about
just what we are seeing.
