The first stage, which is planning , is about finding out the cause of the problem we are facing. At this point, it is worth remembering one of the principles of Kaizen, that of the “5 whys”. We should try to code phone number philippines find out what is most responsible for the situation by “asking why” five times. Of course, it is not always enough to ask “why”, so in the following paragraphs I will describe diagrams to break down the problems and find the most crucial ones. By knowing the cause of the problem, we can obtain any information that can help us solve it and move on to the next step.
The next step is to try to solve the problem . As we know, Kaizen is about taking small steps, so to start with we don't turn the whole company upside down, but simply test the idea on a small scale. In this case, "execute" means "test", and full implementation only takes place in the last phase of the cycle. This approach will be better because our ideas can sometimes go wrong. Being cautious gives us some flexibility and allows us to adapt solutions to reality.
Once we have tested our solution, it is time for the third stage, which is the analysis of its effects . It allows us to find out the validity of the idea and its effectiveness. Of course, the result of a test does not have to be judged by a zero to one system. Even if the solution is good enough to be introduced in its entirety, the "test period" allows us to learn about its imperfections and improve them. The "test" should not be based solely on control, but on the study of the results of the experiment carried out.
The final phase is the implementation of a revised solution . The three previous stages give us the assurance that the results will be satisfactory. Of course, this is not the end of the process, because Kaizen, with which the PDCA model is closely associated, is a continuous improvement, the cycle closes and starts again; once the process is complete, we must look for other areas that we can improve. The repetition of these four steps brings the company closer to excellence.
