The introduction is the first part of your document and includes the context, trigger and question.
The introduction forms a ‘mini narrative' that helps you and your reader come to the same beginning point for your document. It helps you clarify where the story should go and helps the reader join you at that destination.
The standard form will begin with the context, then explain the trigger and lead to the document's primary question. The primary question may be stated or implied, depending upon your purpose and the tone of the document.
