![]() With its continuous implementation, an organization can be proactive in determining any process shortcoming and address problems quickly and accurately. It is simple to use the tool yet very effective in improving a process and the quality of a product or service. ![]() The fishbone diagram is a visual representation of cause and effect relationships. Instead, this activity should be undertaken continuously to be proactive in determining any possible loophole. This technique should not be used as a one-time activity. This technique is widely used in product design, quality improvement, and defect minimization.Instead of pointing out just one reason, this technique gives us a gamut of all the possible reasons that assist not only in identifying the root cause of the current problem and avoid any future mishappening.Looking at how well we addressed the above problem, we have hired consultants from a burger store to identify the reasons for preparing a bad quality burger. We can classify the same in main causes and present it in the fishbone diagram like below: Example #2 # The possible reasons are many, like faulty packaging that led to damage during transit, the wrong product being released for delivery, or the address label on the product wasn’t correct. Let’s try an example where the problem that needs our attention is wrong/delayed/damaged delivery. Examples of Fishbone (Ishikawa) Diagram # Example #1 # We can also create our main causes to group the causes as we deem fit. MachineMaterialsMethodsPersonnel (Men)MeasurementsEnvironmentĪlternatively, we may also use the five whys a technique or the 4 P’s (Product, Policies, Procedures, and Plant). These can be identified by organizing a brainstorming session or minutely following the whole process and identifying all the possible reasons that can lead to quality damage. Under these main causes are listed the causes and sub-causes. Draw branches to the backbones that will list the main causes. Here we mention the subject that needs our attention. How to Create a Fishbone diagram? # Identification of Factors Causing a Defect #įor the identification of factors, we may consider breaking all the reasons under the following main causes: Under these main causes are mentioned the causes and sub-causes. The main causes are mentioned on the tip of bones stretching from the spine bone. As seen in the diagram, the problem/issue is mentioned on the right. Many online websites and templates provide you with ready-to-use diagrams. This diagram is drawn on an excel sheet alternatively, this can be made on word or paint.

On the left runs its spine, which has bone-like arrows pointing to the main causes. The problem is written in the rightmost part, the fish’s head. ![]() Its structure resembles the bone structure of fishes. The name comes from the shape this tool takes after its formation. Now, why is it called a Fishbone diagram? It is not without any reason. ![]()
