  • Smart Answer: The flow, questions and outcomes.

  • Flow: Defines the questions, outcomes and the rules for navigating between them.

  • Landing page: Contains a description of the Smart Answer and the "Start now" button that leads to the first question.

  • Question page: Contains an individual question that's asked in order to help arrive at at an outcome.

  • Outcome page: Contains the result of the Smart Answer based on responses to individual questions.
