Which term describes a structured outline or plan for a written work?

The term that most accurately describes a structured outline or plan for a written work is "blueprint." In the context of writing, a blueprint serves as a detailed guide or schematic that lays out the components and organization of the work. Just as an architect uses a blueprint to visualize and structure a building, a writer employs a blueprint to logically organize thoughts, themes, and ideas in a cohesive manner. This helps ensure that the final work is coherent and effectively communicates its message.

The other terms, while related to planning or structuring, may not convey the same specificity as a blueprint. For example, "framework" can refer to the underlying structure in a more general sense but does not imply the detailed planning aspect that a blueprint provides. Similarly, "strategy" typically relates to the methods or overarching approach used to achieve a goal, while "design" can refer to aesthetics or the arrangement of elements, which doesn't exclusively focus on the written outline itself. Thus, blueprint is the most precise term for the structured outline in question.
