Maintaining Question Types
You can group or classify questions into different types to manage them more efficiently. Use Question Type Maintenance to create, view, edit, or delete question types.
Note: Question types are non-domain-specific.

Question Type Maintenance
Foreground: Questions always appear in the questionnaire; the user answers them.
Background: The system can automatically answer the questions according to configuration rules, but the user can also answer them. You can suppress Background questions so that they do not display in the questionnaire.
