The questions that Rainbird asks the end-user whilst running a query can be grouped together. Grouping questions together allows the end-user to answer a batch of questions at once. It improves the user experience, and can help unfold a logical stream of questions, enabling any Rainbird designer to handle their models’ questions more accurately.
Let’s take as an example a simple “match-making” model, where Rainbird will match 2 people together if they share the same favourite activity and have the same age (± 5 years).
If question grouping is not used, here’s how Rainbird will gather the necessary information:

Note: the question order depends on the position of the conditions in the rules used to satisfy a query.
To avoid confusion and to create a more meaningful questionnaire, the question grouping option can be used. The questions are separated into two groups – one group containing the questions about Person 1, and the other with all the questions about Person 2.
Now, the questionnaire looks like this :

Creating question groups
To create question groups, open the relationship settings for the questions to be grouped, and type in a question group name in the “question group” box. In the example model, two groups have been created, called “Person 1” and “Person 2”:

Notes on question grouping
- Question grouping will trigger all the questions of the same group even if some are not needed for the logic, or even they should not be triggered at that moment.
- Question group names are case sensitive and group names have to be exactly the same in order for the questions to be correctly grouped.
