The purpose of the white paper is to convince an agency, organization, or governmental body to support a proposed idea based on well-research evidence. The white paper should be as long or short as it needs to be to successfully lay out convincing data and argumentation. White papers can appear in many forms, from colorful and dynamic to straightforward and black-and-white. The audience is always considered. While the supporting evidence in the white paper is heavily-research, the tone does not necessarily need to be academic. The tone, voice, and method of communicating data, facts, and figures should be appropriate to the audience's level of knowledge/expertise in the subject.
