Reports:
Reports are documents in which information about a particular matter is presented in a written form. These are common in business practice.
Proposals:
In the academic sense, these are formal written documents in which proposed research work is outlined stating the purpose and rationale for a study, as well as describing the intended method of data collection. A proposal can also be written as motivation for funding for a particular study, project, or research work.
Policies:
Most large organisations set out their rules and regulations in policy documents. The policies reflect the organisation’s principles, procedures, and practices that are used as a basis for decision-making, and as a guide to expected behaviours within the organisation.
