Closing the Strategy Gap Closing the Strategy Gap
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.

Business Intelligence (BI) Business Intelligence (BI) BI is an evolution of decision support
concepts over time. Meaning of EIS/DSS…
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.
![Page 12: Chapter 1: Introduction to Business Intelligence](https://reader035.vdocuments.mx/reader035/viewer/2022062221/56649d835503460f94a6a0c6/html5/thumbnails/12.jpg)
Definition of BIDefinition of BI 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 BIA Brief History of BI
The term BI was coined by the Gartner Group in the mid-1990s
However, the concept is much older 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 BIThe Architecture of BI
A BI system has four major components: 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)
![Page 16: Chapter 1: Introduction to Business Intelligence](https://reader035.vdocuments.mx/reader035/viewer/2022062221/56649d835503460f94a6a0c6/html5/thumbnails/16.jpg)

Components in a BI ArchitectureComponents 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.).

BI ExamplesBI Examples
Epagogix is an analytics based BI system that specializes in predicting success of movies based on a detailed analysis of movie scripts.
National Australia Bank uses data mining to aid its marketing initiatives.
Hoyt Highland Partners, a marketing intelligence firm, assists health care providers with growing their businesses.

Components in a BI ArchitectureComponents in a BI Architecture
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.

Styles of BIStyles of BI
MicroStrategy, Corp. distinguishes five styles of BI and offers tools for each:1. report delivery and alerting2. enterprise reporting (using
dashboards and scorecards)3. cube analysis (also known as slice-
and-dice analysis)4. ad-hoc queries5. statistics and data mining

The Benefits of BIThe Benefits of BI The ability to provide accurate information
when needed, including a real-time view of the corporate performance and its parts
A survey by Thompson (2004) 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 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. e.g., simple-loan approval system
![Page 23: Chapter 1: Introduction to Business Intelligence](https://reader035.vdocuments.mx/reader035/viewer/2022062221/56649d835503460f94a6a0c6/html5/thumbnails/23.jpg)

Automated Decision Making Automated Decision Making
ADS initially appeared in the airline industry called revenue (or yield) management (or revenue optimization) systems. dynamically price tickets based on
actual demand Today, many service industries use
similar pricing models. ADS are driven by business rules!

Intelligence and EspionageIntelligence and Espionage
Stealing corporate secrets, CIA, … Intelligence vs. Espionage
IntelligenceThe 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 Use of data/text/Web mining (see Chapter 4, 5)

Transaction Processing VersusTransaction Processing VersusAnalytic ProcessingAnalytic Processing
Transaction processing systems are constantly involved in handling updates (add/edit/delete) to what we might call operational databases. 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
![Page 30: Chapter 1: Introduction to Business Intelligence](https://reader035.vdocuments.mx/reader035/viewer/2022062221/56649d835503460f94a6a0c6/html5/thumbnails/30.jpg)
Transaction Processing VersusTransaction Processing VersusAnalytic ProcessingAnalytic Processing
Online analytic processing (OLAP) systems are involved in extracting information from data stored by OLTP systems 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 ImplementationSuccessful 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) Provide what is needed to whom he/she needs it
A successful BI system must be of benefit to the enterprise as a whole.
![Page 32: Chapter 1: Introduction to Business Intelligence](https://reader035.vdocuments.mx/reader035/viewer/2022062221/56649d835503460f94a6a0c6/html5/thumbnails/32.jpg)
BI and Business StrategyBI and Business Strategy
To be successful, BI must be aligned with the company’s business strategy. BI cannot/should not be a technical exercise
for the information systems department. BI changes the way a company conducts
business by 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!
![Page 33: Chapter 1: Introduction to Business Intelligence](https://reader035.vdocuments.mx/reader035/viewer/2022062221/56649d835503460f94a6a0c6/html5/thumbnails/33.jpg)
BI for Business StrategyBI 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. 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.
