Therefore, specialized manufacturing flow charts are to be preferred to universal ones if they are to be easy to understand. A small number of symbols logically reduces the range of applications. Understandable flowcharts are therefore characterized by a small, preferably self-referential symbol range. Or to put it another way: No flowchart contributes to understanding until those involved have learned to interpret the symbols used in it in a uniform manner. But does this solve the problem? No.īecause the fact remains: Every type of diagram requires interpretation. Only one thing is clear: There are countless ways to create such diagrams professionally. In addition to the above list, there are countless software tools, each of which has its own focus or, on the contrary, sees itself as a universal tool, e.g. It’s easy to lose interest in the topic, isn’t it? Now let’s go one step further. Quantity flow diagram ( Sankey diagram).Here is an incomplete PFD list with reference to production process flows: For this reason, we know many different types of flowcharts today, some of which are perceived as modeling languages. However, they can be interpreted completely differently by different persons as long as the symbols are not standardized or self-speaking. Therein is the greatest danger of flowcharts: They are apparently easy to understand. What do the colors mean, for example? Or do the shapes have a certain meaning in the PFD? Any flow chart requires interpretation That means only the creator of the flowchart will be able to interpret it correctly. Because such a graphic is first of all free of semantics. Well, let’s say: It could create a basic understanding.
