After analyzing purpose and audience, write a five-part purpose statement that defines the purpose of your document. You use the purpose statement to focus yourself as you write. Later, you make the purpose statement the first sentence in the introduction to focus the reader. If the reader doesn't quickly understand the purpose for the document, the information seems irrelevant, and therefore illogical. Indeed, the purpose statement is the most important sentence in the document.
Here are the five parts of the purpose statement in a typical order, plus an example:
Type of document—report.
What the document does—describes.
What information the audience needs—three energy-saving tips.
What the audience does with the information—reduce utility bills.

In Step 2, you make two decisions about the document: type of document and what the document does.
