When you have determined your information requirements, you can estimate the number of screens that need to be designed. The number will be influenced by the:
Anticipated number of viewer destinations that require different screens
Type and number of monitoring and regulating tasks that can be divided into logical units
Amount of information to be displayed, keeping in mind that displays need to be clear to view in a runtime environment
Note: Using frames is another layout option if you have several objects on a screen that will change during runtime, based on a similar set of conditions.
