# The Use of a Cause and Effect Diagram

The cause and effect diagram is also known as the fishbone diagram. It is one of the many methods used to analyzethe cause of a problem or a condition. It was first founded by Professor Kaoru Ishikawa back in 1943. He is a Japanese scientist with an alchemy major, who is also an alumnus of the University of Tokyo. Often, it is also called the Ishikawa diagram, taken from the founder’s name. This type of diagram has many uses. Some of them are to identify the root of a problem, to get ideas that could give solutions to solve a problem and to help or investigate further facts.

Sample of Cause and Effect Diagram

The main function of the cause and effect diagram is to identify and also organize the causes that possibly arise from certain effects and then to separate the root of the problem. In creating the fishbone diagram, there are a few steps that you need to pay attention to. First, you have to identify the problem. You need to identify the real problem that is happening. One of the main problems that can be seen from the square part of the diagram can be seen from the head of the fishbone diagram. The problem that you are going to identify will be the center of attention in the process of creating the cause and effect diagram too.

In identifying the main factors of a problem, you can place these factors in the “bones” of the diagram. Some of these factors might include human resources, the methods that were used, the operational side of the business, how the products were created, and many more. Finding the possible causes of each factor are also important to do. From the main factor of a problem, you will find a cause to it. All of the possibilities of each cause can be placed in the “little bones” of the diagram. You will need to find out the root of the problem for each cause and possibly the previous causes as well.

After all of the steps above are done, you will need to do some analysis for all the results of the diagram that you have created. When the cause and effect diagram is done, you should be able to see the root of the problem. From these roots, you will need to analyze further and make different priorities in how to handle them in the future. After that, you will find a solution to solve these problems too. In analyzingthe cause and effect diagram, there are 4S that you need to know too. They are the Surroundings, Suppliers, Systems, and Skills. These 4S’s can be used to help you create the diagram.

If you want to create a cause and effect diagram but you have never done it before, you can easily create them by using a template. Some of these templates are available online and some of them might even come for free. For a good result of this kind of diagram, it is best to use a template so you can easily fill in the fields that are available with the team. Once you find a template that is suitable for your company, you can start brainstorming some ideas with your team members too before presenting them to the management.
