COMPUTER-BASED INFORMATION SYSTEMS (CBIS)CBIS)
• CBISs are information systems that rely on computer hardware and software for processing and disseminating info.
• Formal systems are systems resting on accepted and fixed definitions of data and procedures, operating with predefined rules.

22
TECHNICAL APPROACH
• Emphasizes mathematically based, normative models to study information systems, as well as the physical technology and formal capabilities of these systems.
• Computer science: computability, computation, data storage and access.
• Management science: development of models for decision making and management practices.
• Operations research: techniques for optimizing selected parameters of organizations.
![Page 23: The Information Systems Revolution Transforming Business and Management](https://reader033.vdocuments.us/reader033/viewer/2022061120/546c51bfb4af9fd2238b4cb4/html5/thumbnails/23.jpg)
23
BEHAVIORAL APPROACH
• Behavioral issues arise in the development and long-term maintenance of IS.
• Sociologists study IS with an eye toward how groups and organizations shape the development of systems and also how systems affect individuals, groups, and organizations.
• Psychologists study IS with an interest in how formal information is perceived and used by human decision makers.
• Economists study IS with an interest in what impact systems have on control and cost structures within the firm and within markets.

24
SOCIOTECHNICAL PERSPECTIVE
• The challenge and excitement of the information system field is that it requires an appreciation and tolerance of many different approaches.
• We stress the need to optimize the performance of the system as a whole. Both the technical and behavioral components need attention.

SOCIOTECHNICAL PERSPECTIVE
OPTIMIZE SYSTEM PERFORMANCE:
Technology & organization mutually adjust to
One another
Until fit is satisfactory
