  19. Table 1.2: Characteristics of Valuable Data Principles of Information Systems, Seventh Edition

  20. Table 1.2: Characteristics of Valuable Data (continued) Principles of Information Systems, Seventh Edition

  21. System and Modeling Concepts • System: a set of elements or components that interact to accomplish goals • Components of a system • Input • Processing • Output • Feedback Principles of Information Systems, Seventh Edition

  22. Figure 1.3: Components of a System Principles of Information Systems, Seventh Edition

  23. System Components and Concepts • System boundary: defines the system and distinguishes it from everything else (i.e., the environment) • Configuration: the way system elements are organized or arranged • Systems can be classified as simple or complex, open or closed, stable or dynamic, adaptive or nonadaptive, and permanent or temporary Principles of Information Systems, Seventh Edition

  24. Table 1.3: Systems Classifications and Their Primary Characteristics Principles of Information Systems, Seventh Edition

  25. System Performance and Standards • Efficiency: a measure of what is produced divided by what is consumed • Effectiveness: extent to which system attains its goals • System performance standard: a specific objective of a system Principles of Information Systems, Seventh Edition

  26. System Variables and Parameters • System variable: quantity or item controlled by the decision maker • System parameter: value or quantity that cannot be controlled (e.g., the cost of a raw material) Principles of Information Systems, Seventh Edition

  27. Modeling a System • Model: an abstraction that is used to represent reality • Four major types of models: narrative (based on words); physical (tangible); schematic (graphic representation); mathematical (arithmetic representation) Principles of Information Systems, Seventh Edition
