The Plan-Do-Study-Act (PDSA) Cycle is used to help conceptualise the process of continuous, and iterative, improvement.
Also known as
- Deming cycle.
- Improvement cycle.
- Plan-Do-Check-Act (PDCA) cycle.
The model ensures impacts of incremental improvement actions are monitored, measured, learned from, and responded to in appropriate ways.
The four stages of the cycle are show in the following table.

The PDSA cycle is sometimes also described as a spiral to emphasize the repetition of stages in the cycle. [KS – Add diagram]
