When writing a white paper it is important you keep in mind the purpose, audience, and tone.
Often the person reading the white paper will be unfamiliar with the entity, problem, or solution explored in the paper. You must be persuasive, but avoid bias.
Citations often include primary research such as quantitative and qualitative data and secondary research.
Parts of a white paper typically include an introduction, problem statement and exploration, solution explanation, and conclusion. There may be additional parts in the form of visuals (charts, figures, etc.).
