PHYSICAL and CONCEPTUAL SYSTEMS

• Physical system – The business firm – Composed of physical resources

• Conceptual system– Represents a physical system– Uses conceptual resources

• Information•Data

19

A SYSTEMS VIEW

• Business operations are embedded within a larger environmental setting– Reduces complexity– Requires good objectives– Emphasizes working together – Acknowledges interconnections– Values feedback

20

DATA and INFORMATION

• Information processor– Key element in the conceptual system– Computer– Noncomputer– Combination

• Data is the raw material transformed into information

21

EVOLUTION of THE CBIS

• Data Processing (DP)• Management Information Systems (MIS) 1964

– IBM promoted the concept as a means of selling disk files and terminals

• Decision Support Systems (DSS) 1971– Text book’s distinction:

• MIS: Organizational/group - general• DSS: Individual - specific

• Office Automation (OA) 1964• Artificial Intelligence (AI)/ Expert Systems (ES) 1990s

– Heavy investment by businesses
