A proposal is a plan or suggestion, often made in the form of a written document, that is presented to someone with the intention of persuading them to accept or support the idea being proposed. Proposals can be made for a variety of purposes, such as in business, research, or politics. They often include an introduction to the proposed idea, a description of the need or problem that it addresses, and a plan for how the proposal would be implemented. The goal of a proposal is to present a clear, well-reasoned case for why the idea being proposed is worth considering and supporting.
