An Effect-Cause Diagram, also known as a Fishbone Diagram or Ishikawa Diagram, is a tool used to identify the possible causes of a problem or issue. It is called a Fishbone Diagram because of its shape, which looks like the skeleton of a fish. The Effect-Cause Diagram starts with a problem statement or an effect that needs to be addressed. This effect is written at the head of the fishbone, which represents the problem. The major categories of possible causes are then identified, and lines are drawn from the fishbone to each category. These categories can vary depending on the context of the problem, but commonly used categories include people, process, equipment, and materials. Under each category, more detailed causes are identified and connected to the category lines. This process continues until all possible causes have been identified. The diagram can then be used to prioritize the most likely causes and develop solutions to address them. The Effect-Cause Diagram is a useful tool for problem-solving and can help teams identify the root causes of a problem. It allows for a systematic and structured approach to problem-solving, ensuring that all possible causes are considered.
