Hele-Mai Haav: CSC 210’Spring 2002 CSC 230’Spring 2003 Introduction to IS in Business
Objectives • Explain why knowledge of information systems is important for business professionals and identify five areas of information systems knowledge they need. • Give examples to illustrate how E-business, electronic commerce, or enterprise collaboration systems could support a firm’s business processes, managerial decision making, and strategies for competitive advantage.
Objectives • Provide examples of real world information systems, including the people, hardware, software, data, and network resources that compose them. • Provide examples of several major types of information systems from your experiences with business organizations in the real world.
System concepts A system is a group of interrelated components working together toward a common global goal by accepting inputs and producing outputs in an organized transformation process
Feedback and control • Feedback is data about the performance of the system • Ex. Data about sales performance is feedback to a sales manager • Control involves monitoring and evaluating feedback to determine whether a system is moving toward the achievement of its goal. • The control function then makes necessary adjustments to a system's input and processing components to ensure that it produces proper output. • Ex. Self-monitoring or self-regulating heating systems, human body, CAD
System and its environment • A system exists and functions in an environment containing other systems • If a system is a part of larger system then it is called subsystem and larger system is called its environment • Several systems can share the same environment
