Abstract
Consistency is the orderly treatment of a set of linked elements, and it is a necessary characteristic of polished, highly readable prose. Consistency is either “uniform” or “harmonious,” depending on whether a set of linked elements is indivisible or divisible into subsets. From the perspective of text characteristics, we can speak of semantic, syntactic, stylistic, spatial, and mechanical consistency. To deal successfully with consistency problems, technical communicators should establish patterns that are logical, evident, functional, resource efficient, and stable. Because of its importance, the concept of consistency should be more fully recognized. Indeed, consistency should be a component of any comprehensive rhetoric of technical communication.
