P DCA Cycle
What is the Deming Circle (PDCA Cycle)
The Deming circle is based on the assumption that at the basis of every process is a control loop in which it is constantly monitored whether the intended result is actually achieved.
The Deming circle was developed in the 1950s by Dr. WE Deming.
As can be seen from figure 1, four things are important. Firstly, a plan must be drawn up and secondly this plan must be implemented. The third step is to regularly verify whether what has been devised in the Plan has actually taken place in Do. Something must then be done with the finding from Check. After all, it is not useful to just observe (Check) that something did not go as expected, without checking whether this can be avoided in the future. That means that the fourth step is to make changes (Act) to the Plan.
The Deming circle is not a circle for nothing. After Act's decision-making, there must be a new planning. This means that adjustments are devised (Plan), implemented (DO), checked for feasibility (Check) and actions are taken (Act), etc.
