      January 2, 2010 Introduction Information Systems David Asirvatham
    • Systems
      • What is a system?
      • A system is a set of interrelated subsystems which when combined serve a defined purpose and achieve a specific objective.
      • - input; process; output
      • Can you give examples of systems?
      • What is the environment of a system?

      January 2, 2010 Introduction Information Systems David Asirvatham
    • Systems Theory
      • Types of systems
      • Deterministic systems
        • the output can be predetermined
        • input should be invariable
        • e.g. mechanical systems
        • business systems do not come under this catergory
      • Probabilistic or stochastic systems
        • the output cannot be determined precisely; it is only possible to assess their probable output
        • e.g business systems
      • Adaptive or cybernatic systems
        • dynamic to changes in the environment
        • e.g computerised stock control system
