Ishikawa's fishbone diagram template4/22/2024 ![]() The ultimate reasons or findings behind the secondary causes are attached respectively to complete the diagram.The sub-causes i.e., secondary or deeper reasons are rooted under their concerned primary causes.The major factors causing the issue are branched out as primary cause within their respective categories.Also, the team has to ascertain the link between different causes, to identify relevant branch bones. Now, find out the maximum possible causes or reasons contributing to the problem.Next, state the categories under which the causes i.e., manpower, materials, methods, machines, measurement and environment are listed on the diagram.It is stated under the ‘effect’ in the head portion of the fishbone. The foremost step is to diagnose the exact issue being faced by the organization.Given below is a systematic and well-structured procedure of creating an Ishikawa diagram: While drawing the cause and effect diagram, many people get confused about where to start from? Content: Ishikawa (Fishbone or Cause and Effect) Diagram In the above diagram, we have shown two more categories i.e., management and maintenance. However, later on, this diagram was moulded as per the needs of the organization to include or exclude one or more categories. Mother Nature (Environment): This part of the diagram enlightens upon the external causes of the trouble such as the political, social, economic, technological and demographic environment.Materials: The procurement, quality, purchase price, vendor selection, warehousing and handling of the raw material hold the core factors causing problems.Measurement: This section list out the hurdles in analyzing efficiency, quality checks and other process measurements.Methods: The business process including production or manufacturing are deemed to cause trouble such as non-compliance with the set standards and regulations.Machines: A major part of the company’s finance is invested in the machinery and it is considered to be the backbone of corporate functioning.Manpower: Human resource is a vital element of the organization and can be seen as a reason behind most of the corporate failures or achievements.The basic cause and effect diagram proposed in the 1960s comprises of the following ‘6M Categories’: Thus, it is termed as a fishbone diagram. This layout appears like a fishbone where the head section depicts the effect or problem statement, and the middle body is seen as the multiple causes or factors. This visual tool was brought to limelight by a Japanese engineer and quality control expert, Kaoru Ishikawa. It is a problem-solving approach which focuses on uncovering the effect of various factors over a particular issue. In essence, this template empowers users to conduct thorough cause-and-effect analyses, providing a structured framework for identifying and addressing the root causes of problems.Definition: An Ishikawa diagram is the pictorial representation depicting the factors responsible for a certain problem in such a manner that the root cause is identified. You can also download our 6 Ms checklist to help you better log all possible causes under the appropriate categories. Just fill the textboxes with the potential causes under the relevant categories.Īlthough this template uses the 6 Ms approach for labeling the categories, you may use any other approach and create your own branches that best suit your project’s needs. ![]() It comes with ready to fill textboxes which simplify the process of adding the potential causes. ![]() For example, you may increase the number of potential causes per category and change their positions. This template is a Microsoft Excel spreadsheet that you can use and modify to meet your specific needs. Users should be aware that entering multiple sub-causes under one parent cause requires manual intervention. Remember however that the template does only allow to enter causes in a linear sequence. The first variant allows to add only the first level of potential causes, another for two levels, and a third for three levels. This template comes in three different variations, each accommodating different levels of potential causes. You can then plan and implement actions to address the key causes. This fishbone diagram template is designed to help the identification of potential causes related to a specific effect or problem. It is also referred to as cause-and-effect diagram and Ishikawa diagram. The fishbone diagram is an effective tool for visually presenting the relationships between causes and effects in a clear and understandable manner. ![]()
