What type of improvement should be achieved by using the Deming Cycle?

Rapid, one-off improvement contradicts the cyclical, repeating nature of PDCA - the model is explicitly designed to be iterated continuously, not executed once.

A 12-month ROI target is a financial performance metric unrelated to the quality improvement purpose of the Deming Cycle.

Quick wins are associated with short-term tactical gains often used early in a CSI initiative, but they do not describe the overarching goal of the Deming Cycle itself.

The PDCA cycle is structured as a repeating loop where each completed cycle informs the next, producing steady and ongoing improvement over time. In ITIL, it underpins the Continual Service Improvement (CSI) stage, embedding a culture of sustained incremental gain rather than isolated breakthroughs.
