Attachments Signal Substance
Attachments add length. Adding length helps the document seem more
complete or significant. Even if no one refers to the attachments or reads
them, it might make sense to include them because of the perception of
substance they convey.
Components to add to a proposal or report might include:
• a copy of your organization’s warranty or guarantee
• your company’s mission statement
• the executive team or principals’ résumés or CVs
• the data or statistics on which your recommendations are based
• several testimonials, references, or endorsements
• a resource list
• bibliography and endnotes
