When to use a fishbone diagram templateĪ fishbone diagram template can be used for any situation where you need to understand all of the contributing factors to a problem. In doing so, they are able to anticipate the consequences with effective analysis. Teams can use Ishikawa's diagram template to visualize all possible causes of a problem and zero in on the underlying cause. You can add as many as you are able to identify. Each of these represents a higher-level category that needs to be considered.īones: The bones of the diagram branch out from the spine this is where the various potential causes can be listed. On the one end is the head while leading away are all the bones branching off. Spine: Like all fish, the Fishbone diagram has a spine that branches out and provides support. It is the basis for completing the rest of the fishbone diagram template. The fishbone diagram is said to look like a the skeleton of a fish and consists of three main elements that were named with this in mind:įish head: This is the part of the diagram where you write the main problem identified. Ishikawa initially used the diagram in an industrial setting, but over time its use has spread to many more industries. Ishikawa believed that it's better to identify the root cause of a problem and fix it, rather than find a patchwork solution.ĭoing so would avoid the recurrence of these problems, which would improve workflow efficiency. Ishikawa based his diagram on the assumption that every problem is a result of an error or inefficiency. The diagram was first created by Kaoru Ishikawa, an engineer and professor at the University of Tokyo. The fishbone diagram (also known as the Ishikawa diagram) is a root cause analysis tool used to identify possible causes of problems or inefficiencies in a process. A fishbone diagram is particularly useful when you must rely on experience and ideas rather than quantitative data. You start with this definition and then identify contributing factors.The fishbone diagram (also called an Ishikawa diagram or “cause and effect” diagram) can be used to explore the potential causes of a particular issue, enabling your team to find a solution more effectively.Īfter brainstorming ideas, you can use the fishbone diagram template to sort these into groupings, honing in on the root cause of the problem. Suppose you're a product manager and have to solve a trend of getting less and less new sign-ups. Now let's see how to apply this on a practical example. This will depend on your specific problems and identified possible causes. Perhaps you can gather more data/evidence for each root cause candidate or immediately identify the most likely one and quickly try to solve it. There are many possibilities what you can do at this point. The diagram now provides a structure for your most important thinking and next steps. The most important step is looking at all the possible root causes and analysing them. So it's important to capture everything that might explain the problem, even if just partially.Īt this point, you should have a complete diagram but no definitive answer yet. Keep in mind that the problem might not have just one root cause but multiple. First principles thinking is useful here including the "Five whys" method. 3) Find possible root causes related to each factorĪsk "Why is this happening?" Write down each idea as a line under the factor it relates to. You can come up with your own factors or you might use generic categories: People, Equipments, Methods, Measurement, Material and Environment.Ĭategorising is very helpful for breaking down complex problems and looking at them from different perspectives. List out the factors/categories that could be contributing to the problem you're solving. 2) Identify contributing factors or categories The line will be for adding factors in the next step. Start with defining the problem and then drawing a line to the left or right of it (that's up to your preference). This can be done in a group as a workshop but also just as well on your own. Building out this diagram consists of few simple steps.
