4. Overall meaning
“a system to support the decision making function in the organization”.

5. Management?

6. information?
is data that is processed and is presented in a form which assists decision maker.

8. system?
A set of elements which are joined together to achieve a common objective. The elements are interrelated and interdependent.
A system has one or
multiple inputs, these inputs are processed through a transformation process to
convert these input( s) to output.

9. Input: Captures raw data from organization or external environment
Processing: Converts raw data into meaningful form
Output: Transfers processed information to people or activities that use it
- Feedback:
Output returned to appropriate members of organization to help evaluate or correct input stage

10. Why Information Systems??
Four powerful worldwide changes have altered the business environment：
Emergence of the Global Economy
Transformation of Industrial Economies
Transformation of the Business Enterprise
The Emerging Digital Firm

11. Globalization
Management & control in a global marketplace
Competition in world markets
Global work groups
Global delivery systems

12. Transformation of Industrial Economies
Knowledge- and information-based economies
New products and services
Knowledge：A central productive and strategic asset
Time-based competition
Shorter product life
Turbulent environment
Limited employee knowledge base

13. Transformation of the Enterprise
Flattening
Decentralization
Flexibility
Location Independence
Low Transaction & Coordination Costs
Empowerment
Collaborative work and teamwork

14. Transformation of the Enterprise

15. Emergence of the Digital Firm

Creation of new products and services
Occasionally re-creating the organization

20. Contemporary Approaches to Information Systems
Information systems are sociotechnical systems. Although they are composed of machines, devices, and "hard" physical technology, they require substantial social, organizational, and intellectual investments to make them work properly. Since problems with information systems—and their solutions—are rarely all technical or behavioral, a multidisciplinary approach is needed. Technical approach
Behavioral approach

21. Contemporary approaches to information system.

22. The Technical approach to Information System emphasizes Mathematically
based model to study Information Systems, as well as physical Technology and formal
capabilities of these Systems.
The Disciplines that contribute to the
Technical approach are Computer Science, Management Science and Operations Research.

23. Technical approach Computer science Management science
Theories of computability
Methods of computation
Methods of efficient data storage and
access
Models for decision making
Management practices
Management science

24. Technical approach Operations research
Mathematical techniques for optimizing selected parameters of organizations, such as transportation, inventory control, etc.

25. Behavioral Approach Sociology Psychology Economics
Development of systems
System affect individual, groups, and organization.
How human decision makers perceive and use formal information .
Impacts to firm and within markets
－ on control
－ cost structures

26. Sociotechnical view
Optimal organizational performance achieved by jointly optimizing both social and technical systems used in production
Helps avoid purely technological approach
