Part 1. What Is a Fishbone Diagram?
A Fishbone diagram is also called an Ishikawa diagram, root cause analysis diagram, Herringbone diagram, and Cause and Effect diagram. In 1990, Kaoru Ishikawa introduced the term “Fishbone diagram” for the first time.
How Does this Diagram Work?
The Fishbone diagram identifies various factors that can lead to a problem to make it easy for you to eliminate the problem at any stage. Simply put, this diagram helps you identify the root cause of a problem. You can develop an efficient solution to eliminate the problem using the outcomes.
Implementing the Fishbone diagram during the development brainstorming session helps you find the roots of a particular problem or highlight the bottleneck in a specific process. This is done by dividing the root causes of problems into different categories.
Key Elements of a Fishbone Diagram
Generally, the Fishbone diagram has three elements, i.e., the head, the spine, and the branches. The head of the fish assists you in recording a specific problem. The spine or backbone connects all the causes of the problem. At the same time, the bones or branches present all reasons that can result in the main problem.
Well, the elements of the Fishbone diagram may vary depending on the nature of the industry. The critical elements of this diagram for the manufacturing industry are 5Ms, as listed below.
1. Manpower: It is associated with anything that deals with people, like quality control specialists, maintenance teams, operators, supervisors, employees, etc.
2. Machine: It covers all equipment and machines used in the manufacturing process that causes any problem. The causes of problems can be related to assembly, usage, or maintenance.
3. Method: Operators may need to follow the instructions accurately. This is why an evaluation process must ensure everything is going in the right direction.
4. Material: All the resources and supplies required for manufacturing are called material. Improper inspection, mishandling, material defect, and low quality can cause severe problems.
5. Measurement: The tools, strategies, or techniques followed to measure quality standards also play a crucial role in Fishbone analysis.
