cluster analysis of variables (Word method),
components analysis, method of multidimensional
scaling (squared Euclid discrepancies ), and others.
Such information would provide the information
system management with the opportunity to
oversee the total information system quality (across
the whole organization), so as to compare qualities
between the different functional areas of
information system and to review improvement
process of functional or integral information
system. Furthermore, the managent of information
