PDCA means quality management control, from the discovery of the problem --> find ways to solve the problem --> implementation of some of the methods --> and then find the New problems, and then continue into this cycle, in order to continue to improve product quality through this cycle. In catering management can be aimed at a project (such as improving attendance) to operate. To improve the attendance rate, for example: 1, found that the attendance rate is low. (P, find the problem) 2, find the factors affecting the low attendance rate (D, find the crux of the problem) (1) poor quality of meals (2) poor attitude of waiters (3) high price of meals (4) not many types of drinks. (x) The owner is not nice, etc. 3. Analyze the effects of these factors on the low attendance rate and find the biggest one (not necessarily one, it could be more than one) to develop measures to improve this problem (C) 4. Implement these measures and check the effects (A). 5, the effect of the assessment, if the largest that problem is solved, and then from the second or again found that problem and then continue to develop improvement measures - & gt; implementation measures - & gt; assessment for the cycle. Through the above cycle, you can continue to improve attendance. This is the general idea of the PDCA cycle.
