overview
As with other memos, your proposal memo should include an overview section noting the subject of the memo and listing the general headings that it will cover.
introduction
Your introduction should tell the reader what the document will cover and indicate who you are and why you are proposing the product that you are. It should indicate your purpose and goals for creating the product you're proposing, and generally justify what you're proposing to do. You should be indicating the significance of the work you're proposing to create.
problem, motivating factor of interest, or question
Explain the driving factor for creating this proposal. Tell your reader(s) why there is a need for the product you intend to create or the action you intend to undertake. In other words, why are you proposing the thing that you're proposing?
product or action description
Describe, in as much detail as possible, the product you're proposing, or the action you propose to undertake.
implementation
This section provides explanation for how you plan to accomplish the work you're proposing to do. It includes several aspects, that you will probably need to separate into distinct subcategories and treat in some detail, some more than others, depending on the product or action you're proposing.
Methodology- This section explains the methods you plan to use to meet your proposed goals. If it is important to your proposed work, you should explain the type of research methodology you chose to study the content issue (i.e.; quantitative/qualitative, and what kind), and you should explain why you chose one method over the other. In general, this section describes how you will gather the background information you need to create the basis for your work.
author credibility- You should also provide some information indicating your capability for undertaking the task you're proposing to accomplish. You're answering here, why your readers should conclude that you're capable (credible) of doing the job you're proposing to do.
equipment/supplies- Be sure to indicate whether you need any particular equipment or supplies to complete the task you're proposing, and if so, whether they're available and you know how to use them.
schedule- What is your time frame for completing the task you propose and is it reasonable? Be sure to include a schedule with good detail.
any other aspects of your project that indicate its feasibility- You should include any other information, too, that will convince your reader(s) that you can do the job you're proposing.
conclusion
The proposal conclusion sums up everything you've written in the body of the proposal and then notes that on the basis of what's been written above, you're asking that your project proposal be accepted.
