Compare the necessary elements in the introduction of a report to those of a proposal

What will be an ideal response?

Answer: In a report, the introduction establishes the context, identifies the subject, previews main ideas (if using the direct approach), and establishes tone and reader relationship. Necessary elements include authorization, who authorized the report, if applicable. The problem/purpose section explains the reason for the report's existence and what the report will achieve. The scope describes what will and won't be covered in the report. Background information reviews historical conditions or factors that led up to the report. Sources and methods discuss the primary and secondary sources consulted and methods used. Definitions are a list of terms and their definitions, including any terms that might be misinterpreted. Terms may also be defined in the body, explanatory notes, or glossary. Limitations discuss factors beyond your control that affect report quality (but do not use this as an excuse for poor research or a poorly written report). Report organization identifies the topics to be covered and in what order.
In a proposal, the introduction identifies the problem you intend to solve or the opportunity you want to pursue. Elements include a background or statement of the problem that briefly reviews the situation at hand, establishes a need for action, and explains how things could be better. In unsolicited proposals, convince readers that a problem or an opportunity exists. The solution briefly describes the change you propose, highlighting your key selling points and their benefits to show how your proposal will solve the reader's problem. The scope states the boundaries of the proposal—what you will and will not do. Report organization orients the reader to the remainder of the proposal and calls attention to the major divisions of thought.
