The [Interview|https://isci.informatik.uni-wuerzburg.de/javadoc/d3web/de/d3web/core/session/interviewmanager/Interview.html], which can be accessed from the session by using the interview problem solver (PSMethod), determines the next question to be presented to the user. More precisely, a {{FormStrategy}} computes the next {{From}} that is presented in the dialog.
A Form consists of a title and a list of active questions:
