  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
