In-Depth Information
relating to systems output are specified first to verify that the desired solution is being de-
livered. Manual or computerized screen and report layout facilities are used to capture both
output and input requirements.
Using a
screen layout
, a designer can quickly and efficiently design the features, layout,
and format of a display screen. In general, users who interact with the screen frequently
can be presented with more data and less descriptive information; infrequent users should
have more descriptive information presented to explain the data that they are viewing
(see Figure 12.22).

Report layout
allows designers to diagram and format printed reports. Reports can con-
tain data, graphs, or both. Graphic presentations allow managers and executives to quickly
view trends and take appropriate action, if necessary.
Screen layout diagrams can document the screens users desire for the new or modified
application. Report layout charts reveal the format and content of various reports that the
application will prepare. Other diagrams and charts can be developed to reveal the relation-
ship between the application and outputs from the application.
