The first task to perform is to analyze the process. We are going to build a process flow diagram (PFD), to characterize the process correctly. It is necessary to determine where there may be problems and sources of variability. For that, it is necessary to know and, above all, to express on a diagram, the work process.

Look at the following web for obtain the recipe:
Download the PFD template and work on it. The template is in PDF format so you can work on it by hand. In it, draw the flow diagram of the process, determining the current identification method that you would use on the different sources of variability. In the Pictures section, include a sketch of the activity that you are describing at all times.
