Evolution of Executive and Enterprise
Information Systems
DSS and ODSS
1980s: Top execs get Executive
Information Systems
1995+’s: Move to everybody’s
information systems and
enterprise information systems
Definitions follow

Executive Information System
(EIS)
A computer-based system that serves the
information needs of top executives
Provides rapid access to timely information
and direct access to management reports
Very user-friendly, supported by graphics
Provides exceptions reporting and "drill-down"
capabilities
Easily connected to the Internet
Drill down
5
Executive Support System
(ESS)
Comprehensive support system that goes
beyond EIS to include
Communications
Office automation
Analysis support
Intelligence
6
7
Enterprise Information System
Corporate-wide system
Provides holistic information
From a corporate view
Part of enterprise resource planning (ERP)
systems
For business intelligence
Leading up to enterprise information
portals and knowledge management systems
8
Executives’ Role and Their
Information Needs
Decisional Executive Role (2 Phases)
1. Identification of problems and/or
opportunities
2. The decision of what to do about them
Flow chart and information flow (Figure
8.1)
Use phases to determine executives’
information needs

Methods for Finding
Information Needs
Wetherbe's Approach
1. Structured Interviews
IBM's Business System Planning (BSP)
Critical Success Factors (CSF)
Ends/Means (E/M) Analysis
2. Prototyping
Watson and Frolick's Approach
Asking (interview approach)
Deriving the needs from an existing information
system
Synthesis from characteristics of the systems
Discovering (Prototyping)
• Ten methods
Other Methods

22
Multidimensional Analysis
Easy to develop an EIS in an OLAP
system
Most are Web-ready
Can tap into data in a data warehouse
via the Web
Use advanced visualization tools
23

24
Including Soft Information in
EIS
Soft information is fuzzy,
unofficial, intuitive, subjective,
nebulous, implied, and vague
25
Soft Information Used in
Most EIS
Predictions, speculations, forecasts, estimates
(78.1%)
Explanations, justifications, assessments,
interpretations (65.6%)
News reports, industry trends, external survey
data (62.5%)
Schedules, formal plans (50.0%)
Opinions, feelings, ideas (15.6%)
Rumors, gossip, hearsay (9.4%)
Soft Information Enhances EIS Value
26
Organizational DSS (ODSS)
Three Types of Decision Support
Individual
Group
Organizational
Hackathorn and Keen (1981)
27
Organizational decision support
focuses on an organizational task or
activity involving a sequence of
operations and actors
Each individual's activities must mesh
closely with other people's work
Computer support is for
Improving communication and coordination
Problem solving
28
Definitions of ODSS
A combination of computer and communication
technology designed to coordinate and
disseminate decision-making across functional
areas and hierarchical layers in order that
decisions are congruent with organizational goals
and management's shared interpretation of the
competitive environment (R. T. Watson, 1990)
A DSS that is used by individuals or groups at
several workstations in more than one
organizational unit who make varied (interrelated
but autonomous) decisions using a common set of
tools (Carter et al., 1992)
29
A distributed decision support system
(DDSS). Not a manager's DSS, but
supports the organization's division of labor
in decision making (Swanson and Zmud,
1990)
Apply the technologies of computers and
communications to enhance the
organizational decision-making process.
Vision of technological support for group
processes to the higher level of
organizations (King and Star, 1990)
30
Common Characteristics of
ODSS (George, 1991)
Focus is on an organizational task or activity or a
decision that affects several organizational units
or corporate problems
Cuts across organizational functions or hierarchical
layers
Almost always involves computer-based
technologies, and may involve communication
technologies
Can Integrate ODSS with Group DSS and
Executive Information Systems
ODSS are an enterprise information system
directly concerned with decision support

George, Nunamaker & Valacich, 1992:
Classification of ODSS based on Key Issues
Downsizing: Reduction in the number
of human resources and hierarchical
layers- Keys to ODSS:
ODSS to act as knowledge filters and amplifiers
ODSS to handle increased communication caused by an
increase in the span of control
ODSS to integrate the gaps created by the missing Management
39
George, Nunamaker & Valacich, 1992:
Classification of ODSS based on Key Issues
Self-Managed Teams: This address the
gaps.
Need increased coordination tools: Groupware
Need increased flexibility in decision making
Need different types of people (for discussion)
40
George, Nunamaker & Valacich, 1992:
Classification of ODSS based on Key Issues
Outsourcing:
•
Strategic versus tactical issues
•
Coordination issues

Supply and Value Chains and
Decision Support
Supply chain: (originally) flow of
materials from sources to internal
use
Demand chain: flow from inside to
customers
52
Supply Chain
The flow of materials, information, and
services from raw material suppliers
through factories and warehouses to the
end customers
Includes the organizations and processes
that create and deliver value to the end
customers
53
Supply Chain Management
(SCM)
To deliver an effective supply chain
and do it effectively
To plan, organize, and coordinate the
supply chain’s activities
54
SCM Benefits
Reduction in uncertainty and risks in
the supply chain
Positively affect
inventory levels
cycle time
processes
customer service
Increase profitability
55
Supply Chain Components
Upstream
Internal supply chain
Downstream
Involves product life cycle activities
Example (Figure 8.2)
56
57
58
Supply Chain
Related to Porter’s (1985)Value Chain
1. Inbound logistics (inputs)
2. Operations (i.e manufacturing)
3. Outbound logistics (i.e. storage,
distribution)
4. Marketing and Sales
5. Service
59
Supply Chain Problems
Uncertainty in the demand forecast
Uncertainty in delivery times
Quality problems
Poor customer service
High inventory costs
Low revenue
Extra costs
60
Solutions to Supply Chain
Problems
Outsourcing
Buy, not make
Configure optimal shipping plans
Optimize purchasing
Strategic partnerships with suppliers
Just-in-time delivery of purchases
Reduce intermediaries
Reduce lead times (EDI)
Use fewer suppliers
Improve the supplier-buyer relationships
Build-to-order
Accurate demand by working with suppliers
61
Computerized Systems
MRP
ERP
SCM
Integrating the supply chain
62
Enterprise Resource Planning
(ERP)
Objective: integrate all
departments and functions across
an organization into a single
computer system that can serve the
entire enterprise’s needs
63
ERP Software Vendors
SAP
Baan
PeopleSoft
Oracle
J.D. Edwards
Computer Associates
64
ERP
Very (VERY!) expensive
2nd generation: doing better
Early 2000: moving to Web
Will fail if an organization’s business
processes do not fit the ERP system’s
model
65
Application Service Providers and ERP
Outsourcing
ASP: software vendor who leases
ERP-based applications
Outsourcing
Now via the Web
66
