Once your team has identified potential causes, you can move forward in researching and analyzing the causes that are most likely to cause the problem.įishbone diagrams provide areas of focus in handling a problem. The advantage of the fishbone diagram is to identify future areas for possible examination. This category refers to any inputs caused by nature or outside noise variables in our process. And finally, our sixth category is Environment.These can also be issues with the tools used in a process. These are any issues associated with the machine settings. This category captures any procedures that may be lacking. This refers to any kind of gauge or inspection issues that may come up.

How might our materials affect the problem? This usually implies raw materials or equipment materials. This category refers to any specific individual problems we have in operator training or experience. Following are the categories of the Fishbone diagram: A brainstorming session will help you identify as many potential causes as possible to fill in the body of the diagram. To build a fishbone diagram the team members expertise must be utilized as they might include process owners, process supervisors, practitioners or maintenance individuals that bring experience in working within your process. There are many methods you can use to complete this step, but the most important requirement is that you do this through a team activity. The final step of constructing a fishbone diagram is to brainstorm the potential causes of the problem or effect. Every branch is starting from the Fish main bone or a horizontal line, creating an image that looks like the skeleton of a fish.Īfter making the fish body, we can move to the next step, which is to add the labels for the categories at the top of each of the major branches of the fish. Draw six branches leading out of the fish as a skeleton. Then create the body of the diagram using a horizontal line from the problem toward the left side. Once you select this effect or problem, you place it in a box on the right-hand side of a piece of paper or whiteboard. To create a Fishbone diagram following steps can be taken:įirst, we select the effect and identify the potential causes for the issue. It also goes by the name cause-and-effect diagram because the effect is at the head of the fish, and the causes are documented into categories in the middle of the fish. It should be created in a group setting, utilizing the knowledge and experiences of a variety of individuals. It can be used at any stage of a performance excellence project, or on its own to help identify causes of a particular problem. It is hence a basic but important tool that should be covered in any Root Cause Analysis Training.įishbone Diagram is a qualitative tool and is a useful brainstorming technique for identifying possible causes of problems in operational or business processes. Cause and Effect Diagramįishbone Diagram is used for identifying potential causes that may contribute to a problem, also known as the effect. The basic concept was first used in the 1920s and was later refined and made popular by Dr. It is commonly known as the fishbone diagram because it resembles the shape of a fish skeleton. It is a simple yet powerful tool in the Lean/ Six Sigma / Lean Six Sigma / Operational Excellence toolbox.
