Which aspect of instruction writing is essential to consider for clarity?

Clarity in instructional writing is heavily dependent on consistency in terminology. When instructions use the same terms consistently throughout the document, it helps ensure that the reader can easily understand and follow the directions. If different terms are used interchangeably for the same concept, it can create confusion and lead to misunderstandings. For example, if one section refers to a part as "component X" and another section calls it "part X," the reader might not realize they refer to the same item. Therefore, maintaining consistent terminology allows the reader to build a clear mental model of the instructions being provided, thereby enhancing comprehension and reducing the potential for errors during execution.

The other options, while they have an impact on clarity, do not center on the foundational aspect of consistent understanding as strongly as terminology consistency does.
