Also known as pdsa ~PDCA cycle, it is a logical working procedure that can effectively carry out any activity, especially in quality management. The four English letters P, D, C and A have the following meanings:

(1) P (plan)-plan, including the determination of policy objectives and the formulation of activity plans;

② d (do)-execution. Execution is the specific operation to realize the plan content;

③ C (check)-check. It is to summarize the results of the implementation plan, distinguish which is right and which is wrong, clarify the effect and find out the problems;

④A (action)-effect. Process, approve or reject the inspection results. Successful experience should be affirmed, or standardized or standardized in order to promote it appropriately; We should sum up the lessons of failure and avoid recurrence; This round of unresolved problems will be put into the next PDCA cycle.

This is a good way of thinking, which can be effectively used in anything.
