How to use a step change
A step change emphasizes the dramatic, non-linear nature of a transformation, suggesting a jump from one discrete level to another rather than smooth progression. It is used in business, science, and general contexts to highlight significant discontinuous shifts. The term implies both suddenness and magnitude, distinguishing it from gradual or incremental improvements.

A common mistake
Learners sometimes use 'step change' to describe any major change without emphasizing the discontinuous or abrupt nature; it should imply a distinct break or leap rather than simply a large degree of change.
