    • Management Support Systems (MSS) MSS focus on providing information and support for effective decision making by managers.
  11. What are the 3 major types of IS to support decision-making responsibilities?
    • Conceptually, 3 major types of IS to support decision-making responsibilities:
    • Management Information Systems (MIS)

  14. The IS Function represents
    • A vital ingredient in developing competitive products and services that give an organization a strategic advantage in global marketplace.
    • A dynamic, rewarding, and challenging career opportunity for millions of men and women. A key component of the resources,infrastructure, and capabilities of today’s networked business enterprise.
  15. Components of Information Systems
    System Concepts. A system is a group of interrelated components working together toward a mon goal by accepting inputs and producing outputs in an organised transformation process. A system (sometimes called a dynamic system) has three basic interacting components or functions: Input, Processing. Output. A Cybernetic System is self-monitoring (feedback) & self-regulating (control). Feedback is data about the performance of a system. Control involves monitoring and evaluating feedback to determine whether a system is moving toward the achievement of its goals.
  16. The 5 basic resources of IS are
    • People – end users and IS specialists
    • Hardware – physical devices and materials used in information processing including computer systems, peripherals, and media
    • Software - sets of information processing instructions including system software, application software and procedures
    • Data - facts or observations about physical phenomena or business transactions
    • Network - communications media and network infrastructure
  17. Data vs. Information
    • Data – raw facts or observations typically about physical phenomena or business transactions
    • Information – data that have been converted into a meaningful and useful context for specific end users
  18. Network Resources
    • Communications Media – examples include twisted-pair wire, coaxial and fiber- optic cables, microwave, cellular, and satellite wireless technologies.
    • Network Infrastructure – examples include communications processors such as modems and internetwork processors, and communications control software such as network operating systems and Internet browser packages.
  19. Information Systems Activities
    • Input of Data Resources
    • Processing of Data into Information
    • Output of Information Products
    • Storage of Data Resources
    • Control of System Performance
  20. Strategic View of Information Systems
    A Strategic IS uses IT to help an organization gain a competitive advantage, reduce a competitive disadvantage, or meet other strategic enterprise objectives.

    • Competitive Strategy Concepts
    • A strategic IS can be any kind of IT (TPS, MIS, DSS, etc.) that helps an organisation.
