    2

  • Decision Structure

    MIS Module III

    3

    Structured (operational)

    The procedures to follow when decision

    is needed can be specified in advance

    Unstructured (strategic)

    It is not possible to specify in advance

    most of the decision procedures to follow

    Semi-structured (tactical)

    Decision procedures can be pre-specified,

    but not enough to lead to the correct decision
