Fishbone Diagram Template — Fishbone diagram is a method or tool that functions to improve quality. This fishbone diagram is also referred to as a cause-effect diagram. Since the analysis process involves breaking down the whole into its own set of parts, you can also use diagrams created through Cause and Effect Analysis to determine who should be responsible for aspects of the project. If you spend a good amount of time on the process, you might even have a to-do prefix for various members of the project team.
The analogy of a fish head that is made is usually always located on the right. This section writes the problem or topic to be analyzed or to find out the cause of the problem. In the example image above, the topic discussed is about the Quality of Industrial Processes in Manufacturing Plants. This topic will be influenced by the causes that will be written in the fishbone section.
In this fishbone section, write down any categories that can affect the topic written on the fishbone diagram template’s head. Typically, determination 5M1E method used in this category are:
First 5M is Man or people, namely everyone who is involved in a process. Examples include: the ability of inspection officers is not evenly distributed so that the results of quality checks vary.
The second is the method or method of analysis used, such as analysis of: how the process of the fishbone diagram template is carried out, what are the specific needs of the process, such as: work instructions, procedures, regulations, and so on. For example: work instructions posted in the field are not clear so that operators work with inappropriate guidance.
The third is Material, which is all the materials needed to carry out the process such as: raw materials or the basis for making products, stationery, or others. For example: material from supplier or supplier A is less good than supplier B.
The fourth is a machine or machines, namely machines that are needed to carry out direct processes or other supporting work for the fishbone diagram template. The machine in question includes the whole, both production machines or supporting devices such as computers, servers and others.
For example: many machines in the process have not been calibrated, resulting in less quality products. Calibration is checking and setting the accuracy of the machine by comparing it with standard machine specifications.
The fifth is measurement, namely how to retrieve data from the process. What are you collecting data for? The goal is to measure the capability and quality of the process of the fishbone diagram template. With the correct data collection, it can be known the ability and quality of the process accurately. For example: there are 3 work shifts, but the data taken is only during the morning shift so it does not represent the whole process.
1E is the environment, namely the conditions around the process or workplace that affect performance. These environmental impacts can affect either directly or indirectly, such as: air temperature, noise levels, humidity and others. For example: certain air conditions can cause certain metal materials to rust so that the quality of the data decreases.
From the main categories mentioned above, it can be written again into more detailed sub-categories and the analogy into smaller fishbone diagram template branches. And they are as important as the other parts too.
Validation is an action to prove that the method used can achieve the desired results. The validation action taken is aimed at the cause of the problem being analyzed. Why does it need validation? Because not all causes that exist in the fishbone have the same contribution to the problem being sought.
There are causes that contribute greatly to the problem and some are minor, some have very little effect. Therefore it is necessary to validate all causes, after the fishbone diagram template has been made. So that we can present the core causes that really affect the problem.
Cause and Effect
Cause and Effect Flashback is an analysis that is usually used to find out why something went wrong. Your product fails, your client is frustrated, and you lose money. But why? After all, everything was fine until three months ago. By analyzing the production process, you may be able to find a problem to blame. Once you’ve determined where the problem is, you can solve it and form a policy to make sure the same problem doesn’t come back.
Cause and Effect Analysis of the fishbone diagram template can also help you make a positive impact. For example, this month, for the first time, your team has exceeded its sales goals. What went right? It’s easy to say “we were lucky”, but most of the time we make or at least encourage our own luck.
Cause and Effect: Planning for the Future
While Cause and Effect Analysis is usually used to understand what has happened, usually to avoid it happening again, it can also be used to help plan for the future. Instead of trying to explain the results at hand, it is possible to prepare the expected results, and then analyze the elements needed to bring about those results. Once you have a clear idea of what is needed, it is much easier to come up with an action plan that will work.

The Advantages and Disadvantages of Fishbone Diagrams
The advantages of fishbone diagram template are that they can describe every problem that occurs and everyone involved in it can contribute suggestions that might be the cause of the problem. Meanwhile, the lack of Fishbone diagrams is an opinion based tool and is designed to visually limit the ability of the team / user in describing problems using the deep “why level” method, unless the paper used is really large to suit these needs.
If the problem is complex and the timing allows, we can leave the fishbone diagram on the wall for a few days to let the ideas hatch and let passers-by contribute. If the fishbone diagram looks lame or narrow, we can rearrange the fishbone diagram template with different main cause categories. The key to a successful fishbone diagram is to keep asking “Why?”, look at the diagram and look for patterns without saying too much, and involve people who are involved in the problem because they usually understand better the problems on the ground.
