2.7.1 Identify the Feasible Designs
Modern computer technology provides many possible approaches to design-
ing a system configuration. For example, should the user interface employ a
graphical user interface or a text-only screen layout ? Should output informa-
tion be displayed on the screen or printed? Should the output be tabular or
graphic? The developers consider the possible designs that are feasible in terms
of the user needs, and,
for each
, consider the six types of design illustrated in
Figure 2.11.
