After you collect the basic facts about the party you are pitching to, writing the proposal will be a fairly straightforward process. All proposals follow a similar four_section structure: 1) introduction, 2) summary of the situation and needs, followed by 3) descriptions of the idea or the goods, personnel, or services you are offering, including relevant details and costs. Then you conclude with 4) all the information you need to persuade the proposal reader to trust you, such as your experience, credentials, and capabilities.
If you work in a Human Resources/Personnel department at a large corporation, or work for a small agency that sells temporary labor or executive search services, then you're in the business of evaluating personnel needs and pitching people and their skills. You may need to convince your boss or a new client of the need to create one or more new job positions, or persuade the boss or client to fill existing positions with personnel you recommend. Perhaps you are persuasive enough to do that with a phone call or casual conversation in the hallway, but odds are better that you will need to write a proposal to pitch your ideas and persuade the client or upper management.
