What kind of changes fall under the category of improvement changes?

Improvements refer to modifications aimed at enhancing the effectiveness, efficiency, or overall quality of existing processes, systems, or practices within an organization. By focusing on enhancements to processes, organizations strive to optimize performance, reduce costs, or increase employee satisfaction. This can involve refining workflows, introducing new technologies, or implementing best practices to improve overall results.

In contrast, responses to external events are reactive measures addressing unplanned changes or crises, while adjustments due to contingency plans are pre-established strategies to mitigate specific risks. Scaling project scope involves expanding the size or breadth of a project rather than focusing on improving existing processes. Therefore, the most accurate characterization of improvement changes is enhancements to existing processes, which directly align with the definition of continuous improvement in an organization.
