The Ishikawa Diagram or Cause-Effect Diagram is a well known and accepted method to collect the potential causes of a current problem. The Ishikawa analysis serves to present all ideas within the team in a structured brainstorming in a clear graphical way. The methodology helps to prepare an in-depth consideration of the root causes of the problem. The individual ideas on the causes and the relationships between the individual causes are presented. The aim of the Ishikawa Diagram is to visualize problem-relevant factors and their cause-effect relationships systematically and clearly.

For this purpose, all conceivable causes of problems, classified according to the groups man, method, material and machine, and possibly also the environment, are recorded in a herringbone diagram and weighted by the participants according to their relevance to the problem. In order to create an Ishikawa diagram, you need to identify vulnerabilities in advance.

The advantage of this method is the holistic view of the problem, which avoids a one-dimensional view and opens up the possibility of easily involving several persons or groups in the problem analysis. The easy to learn method provides a good understanding of the problem and its possible causes.
