Closing the Strategy Gap

1-10
One of the major objectives of
computerized decision support is to
facilitate closing the gap between the
current performance of an organization
and its desired performance, as
expressed in its mission, objectives, and
goals, and the strategy to achieve
them.



1-11
Then: Executive Information System
Now: Everybody’s Information System (BI)
BI systems are enhanced with additional
visualizations, alerts, and performance
measurement capabilities.
The term BI emerged from industry
apps.

Definition of BI




1-12
BI is an umbrella term that combines
architectures, tools, databases, analytical
tools, applications, and methodologies.
BI a content-free expression, so it means
different things to different people.
BI's major objective is to enable easy access
to data (and models) to provide business
managers with the ability to conduct analysis.
BI helps transform data, to information (and
knowledge), to decisions and finally to action.

A Brief History of BI


The term BI was coined by the Gartner
Group in the mid-1990s
However, the concept is much older





1-13
1970s — MIS reporting — static/periodic reports
1980s — Executive Information Systems (EIS)
1990s — OLAP, dynamic, multidimensional, ad-hoc
reporting -> coining of the term “BI”
2005+ — Inclusion of AI and Data/Text Mining
capabilities; Web-based Portals/Dashboards
2010s — Yet to be seen

The Architecture of BI

A BI system has four major
components:




1-15
a data warehouse, with its source data
business analytics, a collection of tools for
manipulating, mining, and analyzing the
data in the data warehouse;
business performance management (BPM)
for monitoring and analyzing performance
a user interface (e.g., dashboard)

A High-level Architecture of BI
1-16
Copyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall
Components in a BI Architecture

The data warehouse is the cornerstone of any
medium-to-large BI system.



Originally, the data warehouse included only
historical data that was organized and summarized,
so end users could easily view or manipulate it.
Today, some data warehouses include access to
current data as well, so they can provide real-time
decision support (for details see Chapter 2).
Business analytics are the tools that help
users transform data into knowledge (e.g.,
queries, data/text mining tools, etc.).

1-19
Business Performance Management (BPM),
which is also referred to as corporate
performance management (CPM), is an
emerging portfolio of applications within the BI
framework that provides enterprises tools they
need to better manage their operations (for
details see Chapter 3).
User Interface (i.e., dashboards) provides a
comprehensive graphical/pictorial view of
corporate performance measures, trends, and
exceptions.
Copyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall
Styles of BI

MicroStrategy, Corp. distinguishes five
styles of BI and offers tools for each:

The Benefits of BI


The ability to provide accurate information
when needed, including a real-time view of
the corporate performance and its parts

1-21
Faster, more accurate reporting (81%)
Improved decision making (78%)
Improved customer service (56%)
Increased revenue (49%)
See Table 1.2 for a list of BI analytic
applications, the business questions they
answer and the business value they bring.

Automated Decision Making




A relatively new approach to supporting
decision making
Applies to highly structured decisions
Automated decision systems (ADS)
(or decision automation systems)
An ADS is a rule-based system that
provides a solution to a repetitive
managerial problem in a specific area.


Intelligence and Espionage

Stealing corporate secrets, CIA, …


Intelligence vs. Espionage
Intelligence
The way that modern companies ethically and
legally organize themselves to glean as much as
they can from their customers, their business
environment, their stakeholders, their business
processes, their competitors, and other such
sources of potentially valuable information

Problem – too much data, very little value

1-28
Use of data/text/Web mining (see Chapter 4, 5)
Copyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall
Transaction Processing Versus
Analytic Processing

Transaction processing systems are
constantly involved in handling updates
(add/edit/delete) to what we might call
operational databases.




1-29
ATM withdrawal transaction, sales order entry via
an ecommerce site – updates DBs
Online analytic processing (OLTP) handles routine
on-going business
ERP, SCM, CRM systems generate and store data
in OLTP systems
The main goal is to have high efficiency
Copyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall
Transaction Processing Versus
Analytic Processing

Online analytic processing (OLAP) systems
are involved in extracting information from
data stored by OLTP systems




1-30
Routine sales reports by product, by region, by
sales person, etc.
Often built on top of a data warehouse where the
data is not transactional
Main goal is effectiveness (and then, efficiency) –
provide correct information in a timely manner
More on OLAP will be covered in Chapter 2

Successful BI Implementation



Implementing and deploying a BI initiative is
a lengthy, expensive and risky endeavor!
Success of a BI system is measured by its
widespread usage for better decision making.
The typical BI user community includes

All levels of the management hierarchy (not just
the top executives, as was for EIS)


1-31
Provide what is needed to whom he/she needs it
A successful BI system must be of benefit to
the enterprise as a whole.

BI and Business Strategy

To be successful, BI must be aligned with the
company’s business strategy.


BI changes the way a company conducts
business by



1-32
BI cannot/should not be a technical exercise for
the information systems department.
improving business processes, and
transforming decision making to a more
data/fact/information driven activity.
BI should help execute the business strategy
and not be an impediment for it!
Copyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall
BI for Business Strategy

Strategy should be aligned with BI/DW – has the
capability to execute the initiative by establishing
a BI Competency Center (BICC) which can:


Demonstrate linkage – BI to strategy.
Encourage interaction between the potential business
users and the IS organization.




1-33
Both sides have a lot to learn from each other
Serve as a repository and disseminator of best BI
practices among the different lines of business.
Advocate and encourage standards of excellence.
Help stakeholders understand the crucial role of BI.

Issues for Successful BI

Developing vs. Acquiring BI systems





Developing everything from scratch
Buying/leasing a complete system
Using a shell BI system and customizing it
Use of outside consultants?
Justifying via cost-benefit analysis


It is easier to quantify costs
Harder to quantify benefits

1-35
Most of them are intangibles
Copyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall
Issues for Successful BI

Security and Privacy



Still an important research topic in BI
How much security/privacy?
Integration of Systems and Applications
