If the finished product has gone through a design section, a production section, a painting section and a packaging section, each of those phases would form one branch. In this case, the fish bones on the diagram would be the different phases or steps of the process. Meaning that the possible causes (the branches) are part of the main body.Ī vehicle would be a great example: if there has been a mistake during its production, the root of any mistake arising could be found among one of its components: the engine, its stopping system, the insides… Process flow method This modality of the Ishikawa Diagram is best for those scenarios where the main issue has something to do directly with its nature.
