You can define requirements assuming that a requirement is satisfied by the receipt and validation of a certain document or set of documents. The documents needed to satisfy a requirement may be any combination of the following:

• System-produced documents, for example, a loan application prefilled with the borrower’s information.
• Documents sourced outside the system, for example, an applicant’s tax return from the previous year or a form produced by an outside form-generation system.

After a document has been completed by the applicable parties, you can scan it into a document repository and then link the image to one or more requirements that call for it. After you associate an image with a requirement document entry, you can validate it as described later in this chapter.
