Which document is not primarily focused on user interaction or operation guidance?

The proposal is the document that is not primarily focused on user interaction or operation guidance. Instead, a proposal is typically written to persuade a reader or organization to support a specific project, initiative, or idea. It generally outlines plans, goals, costs, and benefits associated with a proposed action or project. Its purpose is more about providing information and justifying a course of action rather than giving the reader step-by-step instructions or guidance on using a product or service effectively.

In contrast, instructions, training manuals, and operator's manuals are all designed to enhance user comprehension and interaction with a system or product. Instructions provide specific, actionable steps for completing tasks, training manuals are comprehensive references intended to enhance knowledge and skills in a particular area, and operator's manuals are detailed guides that explain how to use equipment or software effectively and safely.
