A decision tree is essentially comprised of:
- Questions: the questions users will answer on the decision tree. Questions can be formatted as either select or numeric question types.
- Results: result bodycopies are created to display to users based on their responses.
- Answer destinations: response-based destinations for questions on the decision tree. An answer destination can be another question or a result bodycopy. This allows you to cater the questions and results displayed specifically, based on the responses of a user.
The diagram below displays the process of a decision tree asset using select question types.
A different set of questions will be displayed to a user depending on their responses (options A, B or C), ultimately leading to differing result pages.
For example, answering B for Q1, A for Q2 and A for Q3 will present the R2 result page to the user; while answering C for Q1 and B for Q2 will present the R5 result page.

The decision tree asset can also implement a points-based system where point values can be accumulated based on the responses given. Response bodycopies can then be allocated a points range and are dynamically displayed, based on the accumulation of points once the user reaches the end of the decision tree.
Once your decision tree is created, you can configure its settings on its associated asset screens.
The majority of these screens are the same or similar to those for a standard page, custom form and online poll.
