Hence, it serves as “the mother of all white papers” when marketing to the federal government. Hoffman gathered and refined these practices during engagements over a 30-year period. In addition, we interviewed federal government contracting professionals and federal government leaders. The practices are particularly applicable to prime contractors and subcontractors seeking to enhance their content marketing with the federal government. Using white papers for marketing helps position government contractors as subject matter experts.
