What is a Fishbone Diagram?

The Fishbone diagram, also known as the Ishikawa diagram or the Cause and Effect diagram, is a powerful root cause analysis tool utilized across various industries. The Fishbone diagram is a visual representation that helps teams to analyze potential factors causing a problem systematically. It has a shape like the skeleton of a fish. It categorizes the causes into major branches according to the theme. This structured approach promotes collaboration and helps in thorough root cause investigation.

Here is how Fishbone analysis works:

Main Problem Statement: The “fish head” of the fish skeleton represents the potential cause of a problem you are trying to solve.

Major Categories: The “backbone” or “fish spine” of the fish skeleton is divided into major categories that impact the problem. The spine of the fish represents the main flow of the process, with smaller bones branching out. Common categories of fishbone analysis include:

People: This includes human factors like skills, training, and motivation.
Processes: This consists of workflows, procedures, and systems.
Equipment: This includes tools, machinery, and technology.
Materials: This shows raw materials, supplies, and components.
Environment: This includes external environmental factors like weather, regulations, and competition.

Root Causes: The “bones” branch out from the major categories to represent specific potential causes within each problem category.

Problem-solving: It helps break down complex problems into small, manageable parts, which makes it easier to find solutions.
Quality Improvement: It is used in quality control processes to identify defects and helps maintain and improve product or service standards.
Decision-Making Support: The Cause and Effect diagram provides a clear visual representation of causes and helps prioritize them based on their impact. This helps in better and more informed decision-making.
Team Collaboration and Brainstorming: It encourages discussions and cross-functional teamwork by visually mapping out ideas and causes.
Strategic Planning and Analysis: It helps to assess specific factors affecting the goals and guides the development of strategies to achieve the objectives.

How to Make a Fishbone Diagram in PowerPoint?

Here are the steps to make a fishbone diagram in PowerPoint-

Identify the Problem: The first step in a cause and effect analysis is problem identification. It includes – describing the nature of the problem, the magnitude of the problem, the person involved, when and where it occurs, etc. On your Fishbone diagram in PowerPoint, this will appear at the head of the fish—clearly defining the problem lays the groundwork for effective problem-solving.
Work on the Main Causes of the Problem: This stage involves identifying the root causes of the problem. Highlight as many potential causes as possible that can be a part of the problem.
Identify the Sub-Causes Through the Main Causes: Every major problem involves sub-causes that contribute to the occurrence of the primary cause. This step involves identifying the possible additional causes related to the major problems identified in step 2.
Analyze the Diagram: By this step, a diagram would be ready, containing all the possible and potential causes of the problem that you could think of. This diagram now needs to be reviewed as a whole. These problems need to be analyzed in detail. Depending on the problems’ priority and urgency, you can dive further into each problem to investigate it critically.
Derive an Action Plan: After knowing the problem and its causes in detail, the final task is to derive an action plan. Outline the best approach to address the problem and come up with the most viable solution for it.
