Prerequisites determine what is needed to begin meeting the Requirements. When selecting Prerequisites, keep in mind they are in your story as essential steps or items that must be met or gathered to attempt a Requirement. The Type of Requirements much more heavily influences the appropriate Type of Prerequisites than the Type of Goal.

Prerequisites may open the opportunity for easy ways to bring in Dividends, Costs, or even Preconditions (which we shall discuss shortly.) Certain Types of considerations may be more familiar to you than others because of your personal life experience. They will likely be a better source of material from which to draw inspiration. Choosing a familiar Type will help you later when it becomes time to illustrate your story points in Storyencoding.
