Analysis of the factor of dicrepancies in the
information system successfulness between IT
specialists and users, in sense mentioned above,
leads toward several conclusions:
First of all, it has been shown that seven
new factors of information system
successfulness are very important and
should be included in the instrument for
measuring the level of information system
success. Those factors, together with 39
factors listed by Bailey and Pearson, cover
all 8 dimensions of information system
performances.
Second, there are no important differences
between grading importance by information
system managers and information
technologies specialists. The same
conclusion can be drawn from grading
importance by user managers and users.
Also, it has been shown that there are
significant discrepancies between
information system manager and user
manager, but there are significant differences
in importance ratings of information
technology specialists and information
system users.
Third, five most important factors of
information system successfulness pointed
out by information system managers are
almost identical with the ranking of the most
important factors of information system
successfulness according to information
technologies specialists, users and user
managers. The main difference lays in the
factor of capabilities of the top management.
Users see it as the most important factor for
information system successfulness, while
managers think of it as moderately
important. Consequently, top management
must show enthusiasm and support to
information technologies specialists, how
they would use possibilities of information
system for their managerial process. Only
trough that effort can the user be
encouraged to use more functions of
information system. This could, in return,
increase the application of information
system in their everyday work and improve
possibilities for success of information
system.
