What are QC and PDCA?

QC is the abbreviation of QUALITY CONTROL in English. The Chinese meaning is quality control. Its definition in ISO8402:1994 is "the operating techniques and activities adopted to meet quality requirements." Some organizations that implement ISO9000 will set up such a department or position to be responsible for the quality control functions required by the ISO9000 standard. Those who perform such work are called QC personnel, which is equivalent to product inspectors in general enterprises, including incoming inspectors. (IQC), process inspector (IPQC) and final inspector (FQC)

The four English letters of PDCA and their meanings in the PDCA cycle are as follows:

1. P (Plan) - Plan, determine policies and goals, and determine activity plans; 2. D (Do) - Execute, do it on the spot, and realize the contents of the plan; 3. C (Check) - Check, summarize the execution plan The results, pay attention to the effects, and identify problems; 4. A (Action) - Action, process the results of the summary inspection, affirm the successful experience and promote and standardize it appropriately; summarize the lessons of the failure to avoid recurrence and failure. The solved problems are put into the next PDCA cycle.

The PDCA cycle is actually a logical work procedure for effectively performing any work. In quality management, the PDCA cycle has been widely used and achieved good results, so some people call the PDCA cycle the basic method of quality management. The reason why it is called the PDCA cycle is that these four processes are not completed once but are carried out over and over again. After a cycle is completed, part of the problems have been solved. There may be other problems that have not yet been solved, or new problems have arisen, and then the next cycle is started
