4. 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

5. 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

6. Executive Support System (ESS)
Comprehensive support system that goes beyond EIS to include
Communications
Office automation
Analysis support
Intelligence

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

9. Methods for Finding Information Needs

Critical Success Factors (CSF)
Ends/Means (E/M) Analysis
2. Prototyping

Communication

11. Critical Success Factors (CSF)
Monitored by five types of information
1. Key problem narratives
2. Highlight charts
3. Top-level financials
4. Key factors (key performance indicators (KPI))
5. Detailed KPI responsibility reports

19. Including Soft Information in EIS
Soft information is fuzzy, unofficial, intuitive, subjective, nebulous, implied, and vague

20. 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

21. Organizational DSS (ODSS)
Three Types of Decision Support
Individual
Group
Organizational
Hackathorn and Keen (1981)

22. Computer support is for
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

23. 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)

24. A distributed decision support system (DDSS)
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)

25. 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

26. 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

27. 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

28. Supply Chain Management (SCM)
To deliver an effective supply chain and do it effectively
To plan, organize, and coordinate the supply chain’s activities

29. SCM Benefits Reduction in uncertainty and risks in the supply chain
Positively affect
inventory levels
cycle time
processes
customer service
Increase profitability

30. Supply Chain Components
Upstream
Internal supply chain
Downstream
Involves product life cycle activities
Example (Figure 8.2)

31. Supply Chain
Related to the Value Chain Model (Porter)

32. Supply Chain Problems Uncertainty in the demand forecast
Uncertainty in delivery times
Quality problems
Poor customer service
High inventory costs
Low revenue
Extra costs

33. 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
