                                      1.  Support for decision makers, mainly in semistructured and unstructured situations,
                                         by bringing together human judgment and computerized information. Such prob-
                                         lems cannot be solved (or cannot be solved conveniently) by other computerized
                                         systems or through use of standard quantitative methods or tools. Generally, these
                                         problems gain structure as the DSS is developed. Even some structured problems
                                         have been solved by DSS.
                                      2.  Support for all managerial levels, ranging from top executives to line managers.
                                      3.  Support for individuals as well as groups. Less-structured problems often require the
                                         involvement of individuals from different departments and organizational levels or
                                         even from different organizations. DSS support virtual teams through collaborative
                                         Web tools. DSS have been developed to support individual and group work, as well
                                         as to support individual decision making and groups of decision makers working
                                         somewhat independently.
                                      4.  Support for interdependent and/or sequential decisions. The decisions may be made
                                         once, several times, or repeatedly.
                                      5.  Support in all phases of the decision-making process: intelligence, design, choice,
                                         and implementation.
                                      6.  Support for a variety of decision-making processes and styles.
                                      7.  The decision maker should be reactive, able to confront changing conditions quickly,
                                         and able to adapt the DSS to meet these changes. DSS are flexible, so users can add,
                                         delete, combine, change, or rearrange basic elements. They are also flexible in that
                                         they can be readily modified to solve other, similar problems.
