Fishbone or Ishikawa Diagram is a visual tool for analyzing the root causes of a problem which was developed by Dr. Kaoru Ishikawa. It helps to identify many possible causes for an effect or a problem.
The diagram is created using a grid of six lines that branch outward from a central line. These six lines are labeled with the five “Ws” and an “H”. The five “Ws” are Who, What, When, Where and Why. The “H” stands for “How”. This is done to represent the categories of involvement in the problem. These categories can either be people, materials, tools, machines, environment, or any other factor involved in the process or activity.
The first step when using Fishbone or Ishikawa Diagram is to identify the problem. Once the problem is identified then the diagram is used to analyze the root causes of the problem. This is done by writing a statement at the head of the diagram describing the problem. Then each category of the diagram (“Who”, “What”, “When”, “Where”, “Why”, and “How”) is then filled out by brainstorming and listing out the various possible causes of the problem. Once this is done the causes are then assessed and organized.
The Fishbone diagram is a useful tool for identifying the causes of a problem and helping come up with solutions. It is useful in group problem solving exercises because it encourages the group to work together and come up with solutions. The organized structure of the diagram also makes it particularly easy to visualize what actions can be taken to address the problem.
It is important to remember when using the Fishbone Diagram that it does not guarantee solutions to the problem, but rather identifies potential causes of the problem. After the causes are identified then solutions can be developed in order to address and solve the problem. Furthermore, the Fishbone Diagram is only useful if it is constructed properly. It must include both the potential causes and contributors of the problem and still remain organized enough that results can be easily pulled from the diagram.
In conclusion, Fishbone or Ishikawa Diagram is a valuable tool for problem solving in a team setting. It provides an organized and visual approach to identifying and assessing the causes of a problem and subsequently finding solutions. Ultimately, if used correctly, it can help to bring out optimal solutions as well as help to create stronger working relationships between team members.
