PDCA is an improvement cycle based on the scientific method of proposing a change in a process, implementing the change, measuring the results, and taking appropriate action. The cycle was devised by J. Edwards Deming in the 1950s

Confirm continued improvement
What was learnt?

Is the problem completely solved?
|Act / Adjust||Identify further improvements
