Structured vs. Semi-Structured
• For each decision you make, the decision will fall into one of the following categories:– Structured Decisions– Unstructured – Semi-Structured
4
Structured Decisions
• Often called “programmed decisions” because they are routine and there are usually specific policies, procedures, or actions that can be identified to help make the decision– “This is how we usually solve this type of
problem”
5
Unstructured Decisions
• Decision scenarios that often involve new or unique problems and the individual has little or no programmatic or routine procedure for addressing the problem or making a decision
7
The Role of the Decision Maker• Decision makers can be
– Individuals– Teams– Groups– Organizations
• All of these types of decision makers will differ in their knowledge and experience; therefore, there will be differences in how they will react to a given problem scenario
8
The Decision Making Process
• Regardless of the type of decision maker, all decisions involve the following steps– Intelligence – Design– Choice – Implementation
12
How can IT be used to support decision makers?
• By supporting various individual and team activities and roles:– Communication and team interaction– The assimilation and filtering of data– Assist with problem recognition– Assist with problem solving– Putting together the results into a cohesive package
13
Types of Managerial Support Systems and Applications
• Decision Support Systems– Geographic Information Systems (GIS)– Data Mining– Group Support Systems
• Business Intelligence Systems• Knowledge Management Systems• Artificial Intelligence• Expert Systems• Neural Networks• Virtual Reality
DECISION SUPPORT SYSTEMS
• Designed to assist decision makers with unstructured problems
• Usually interactive• Incorporates data and
models• Data often comes from
transaction processing systems or data warehouse
15
DECISION SUPPORT SYSTEMS
Three major components
16
Decision Support Systems (DSS)DSS can be classified as– data-oriented
• provide tools for the manipulation and analysis of data
– model-based• generally have some kind of mathematical model of the decision
being supported
17
So, how do decision support systems benefit decision makers?• Supplements the decision maker
• Allows improved intelligence, decision, and choice activities
• Facilitates problem solving
• Provides assistance with non-structures decisions
• Assists with knowledge management
18
Spatial DSS: A Geographic Information System
• A geographic information system (GIS) is a computer-based information system that provides tools to collect, integrate, manage, analyze, model, and display data that is referenced to an accurate cartographic representation of objects in space.
(Mennecke, Dangermond, Santoro, Darling, & Crossland, 1995).
19
Location Based Services
• Location-based services incorporate information about the user's location into the provision of products or services. These include…– Locator services (e.g., where’s the closest ATM?)– Navigation systems (e.g., in the car or on your PC)– M-commerce applications (e.g., proximity alerts,
closest service, mobile advertizing)
20
GIS Examples
• Online:– www.MapQuest.com – Maps.google.com
• Desktop– ArcGIS by ESRI– MS MapPoint 2004
21
GISs – systems based on manipulation of relationships in space that use geographic data
GEOGRAPHIC INFORMATION SYSTEMS
– Early GIS users:
• Natural resource management• Public administration• NASA and the military• Urban planning• Forestry• Map makers
22
Business Adopts Geographic Technologies
GEOGRAPHIC INFORMATION SYSTEMS
– Business uses:• Determining site locations• Market analysis and planning• Logistics and routing• Environmental engineering• Geographic pattern analysis

• Approaches to representing spatial data:
– Raster-based – rely on dividing space into small, uniform cells (rasters) in a grid
– Vector-based GISs – associate features in the landscape with a point, line, or polygon
– Geodatabase model – uses object-oriented data concepts
What’s Behind Geographic Technologies
GEOGRAPHIC INFORMATION SYSTEMS
GEOGRAPHIC INFORMATION SYSTEMS
Coverage model uses different layers to represent similar types of geographic features in the same area
26
• Questions geographic analysis can answer:
– What is adjacent to this feature?
– Which site is the nearest one?
– What is contained within this area?
– Which features does this element cross?
– How many features are within a certain distance of a site?

• Type of DSS to support a group rather than an individual
• Specialized type of groupware• Attempt to make group meetings more
productive• Now focus on supporting team in all its
endeavors, including “different time, different place” mode – virtual teams
GROUP SUPPORT SYSTEMS
Middle managers spend 35%, and top managers
spend 50-80% of time in meetings!

Executive Information Systems (EIS)/ Business Intelligence Systems
– Hands-on tool that focuses, filters, and organizes information so that an executive can make more effective use of it
– User base for EISs has expanded to encompass all levels of management• Today also called performance management software
– Focus on competitive information…
today referred to as business intelligence systems

Artificial Intelligence
• Artificial intelligence systems include the people, procedures, hardware, software, data and knowledge to develop computer systems and machines that demonstrate characteristics of intelligence.
37
Intelligent Systems • Turing’s test for Artificial Intelligence (AI)
– place a computer and a human in two separate rooms
– an interviewer in a third room, who cannot see the human or the computer user, asks questions that are passed to the computer and to the human
– if the interviewer cannot tell the difference between the answers from the computer and the human, the machine is said to exhibit intelligent behavior
38
AI Versus Traditional Programs
• AI programs manipulate symbols or rules rather than numbers
• AI programs are generally non-algorithmic often employing heuristics or rules of thumb
• Many AI programs are concerned with pattern recognition
39
• Six areas:• Natural languages• Robotics• Perceptive systems • Genetic programming • Expert systems • Neural networks
AI – the study of how to make computers do things that are currently done better by people

41
Expert systems – attempt to capture the expertise of humans in a computer program
EXPERT SYSTEMS
• Knowledge engineer: – A specially trained systems analyst who works
closely with one or more experts in the area of study
– Tries to learn about how experts make decisions
– Loads information (what learned) into module called knowledge base
42
EXPERT SYSTEMS

46
Neural networks – attempt to tease out meaningful patterns from vast amounts of data
• Process:1. Program given set of data2. Program analyzed data, works out correlations, selects
variables to create patterns3. Pattern used to predict outcomes, then results compared to
known results4. Program changes pattern by adjusting variable weights or
variables themselves5. Repeats process over and over to adjust pattern6. When no further adjustment possible, ready to be used to
make predictions for future cases

Neural Networks• Two Types:
– Biological neural networks– Artificial neural networks
• The most popular type of artificial NN are used to classify input into different categories
• A neural network has to be first trained by presenting it with past cases– After training the network can be used for
classification
49
50
Intelligent Agents
• An agent is a piece of software that performs a task for its owner – involves AI combined with networks– applications for intelligent agents have
been for consumer tasks like shopping and providing recommendations based on profile matches
KNOWLEDGE MANAGEMENT SYSTEMS
What is Knowledge management (KM)?
– Practices to manage Organizational knowledge
– Strategies and processes for identifying, creating, capturing, organizing, transferring, and leveraging knowledge held by individuals and the firm
52
Data is turned into information, but the decision maker also needs Knowledge to make decisions
• Types of knowledge:– Descriptive Knowledge– Procedural Knowledge– Reasoning Knowledge
• Forms of Knowledge – Tacit Knowledge– Explicit Knowledge

+…)
• Process-oriented way of doing business- Not separate systems for separate functions
- Support for “Order fulfillment,” not just Sales
• Usually purchased from a software vendor
• ERP = “First wave” of enterprise system packages“Later waves” of enterprise system packages
- Customer relationship management (CRM)
- Supply chain management (SCM) systems

3 Modules for Value-Chain Activities
2 Modules for Enterprise Support Activities
By mid-1990s, SAP and other vendors designed “suites” of integrated modules for “back-office” transaction processing that eliminated the need for many custom-developed interfaces
• Suite from one vendor OR “best of breed” from multiple vendors
• Some organizations implement Enterprise Support modules only ( Financials, HR)
• Value-Chain module implementations involve large investment of money and people resources because of impact on business
• Have become “essential” systems in many industries

Figure 5.6 Key Functional Areas of SAP ERP
• Support for Cross-Functional processes - Modules were designed to support business processes that involved
multiple business functions and multiple geographic locations
• Access to Integrated Data via a unified platform- Data entered into one module could be accessed in real-time by other
modules, by employees in dispersed business units, if a single centralized database is implemented.
• Support for Global Transactions - National currencies are automatically converted to the parent firm’s currency- Employees in different countries can see the same screen in their own
languages
