When faced with a complex problem or issue, it can be difficult to identify the underlying causes and find a solution. This is where the blank fishbone diagram comes in. This visual tool, also known as the Ishikawa diagram or cause-and-effect diagram, allows teams to brainstorm and organize potential causes related to a specific problem or issue. By visually mapping out different categories and their potential sub-causes, teams can explore all possible contributing factors and pinpoint the root cause of a problem.
In this article, we will discuss what a blank fishbone diagram is, why it is useful, how to create one, examples of how it can be used, and tips for successful implementation.
What is a Blank Fishbone Diagram?
A blank fishbone diagram is a visual tool that helps teams visually map out different categories and their potential sub-causes to identify the root cause of a problem. The diagram is shaped like a fish skeleton, with the problem or issue being analyzed at the head of the fish and the potential causes being categorized into different branches or “bones.” The main categories usually include people, process, equipment, materials, environment, and management, although they can be customized to fit the specific problem or issue being analyzed.
Each branch of the fishbone diagram represents a potential cause, and sub-branches can be added to further break down the causes into more specific factors. The diagram allows teams to brainstorm and organize their thoughts in a structured manner, ensuring that no potential cause is overlooked. By visually mapping out the different categories and their potential sub-causes, teams can gain a better understanding of the complex relationships between various factors and identify the root cause of the problem.
Why Use a Blank Fishbone Diagram?
The blank fishbone diagram is a valuable tool for root cause analysis for several reasons:
- Organized brainstorming: The diagram provides a structured framework for brainstorming and organizing potential causes. It helps teams think systematically and ensures that all possible contributing factors are considered.
- Visual representation: The diagram provides a visual representation of the problem and its potential causes. This makes it easier for teams to understand the relationships between different factors and identify the root cause.
- Collaboration: The diagram promotes collaboration and teamwork. It allows team members to contribute their ideas and perspectives, ensuring a comprehensive analysis of the problem.
- Efficient problem-solving: By identifying the root cause of a problem, teams can focus their efforts on addressing the underlying issue rather than treating the symptoms. This leads to more effective and efficient problem-solving.
How to Create a Blank Fishbone Diagram
Creating a blank fishbone diagram is simple. Here are the steps to follow:
- Identify the problem: Clearly define the problem or issue that you want to analyze using the fishbone diagram.
- Create the main categories: Determine the main categories that are relevant to the problem. These categories can be customized to fit the specific context.
- Add the potential causes: Under each main category, brainstorm and list the potential causes or factors that could contribute to the problem.
- Identify sub-causes: If necessary, further break down the potential causes into more specific factors or sub-causes.
- Draw the diagram: Using a whiteboard, paper, or a fishbone diagram template, draw the diagram with the problem or issue at the head of the fish and the main categories as the branches.
- Add the potential causes: Write down the potential causes under each branch, ensuring that they are properly categorized.
- Analyze and identify the root cause: Discuss and analyze the potential causes, considering their relationships and impact. Identify the most likely root cause of the problem.

Tips for Successful Implementation
Here are some tips to ensure the successful implementation of the blank fishbone diagram:
- Involve a diverse team: Include team members with different perspectives and expertise to ensure a comprehensive analysis of the problem.
- Encourage open and honest communication: Create a safe and supportive environment where team members feel comfortable sharing their ideas and opinions.
- Focus on the process, not individuals: Emphasize that the purpose of the fishbone diagram is to identify the root cause of the problem, not to assign blame to individuals.
- Use data and evidence: Support the analysis with data and evidence whenever possible. This helps to validate the potential causes and increases the credibility of the analysis.
- Continuously improve: Use the insights gained from the fishbone diagram analysis to implement changes and improvements. Monitor the results and refine the analysis as necessary.
The blank fishbone diagram is a powerful tool for root cause analysis. By visually mapping out different categories and their potential sub-causes, teams can identify the underlying causes of a problem and develop effective solutions.
Whether you are in manufacturing, healthcare, software development, or any other industry, the fishbone diagram can help you gain a deeper understanding of complex issues and drive meaningful change.
