How Do You Create a Fishbone Problem-Solving Diagram?


Quick Answer

To draw a fishbone mind-mapping diagram, draw a box in the middle of the left side of the page, and write the problem in it. From the problem box, draw a line along the center of the page. Think of the problem's major factors, and draw a labeled, diagonal line away from the center line for each one.

The fishbone diagram was created by professor Kaoru Ishikawa in the 1960s and later published in his 1990 book "Introduction to Quality Control." The diagram may also be referred to as the Ishikawa diagram for its creator.

The purpose of the fishbone diagram is to help problem solvers think through causality in a structured manner. Although initially intended as a quality control tool, the diagram can be used to address may other problems that involve cause and effect. For example, it can be used to analyze the root cause of a problem, bottlenecks in a process or reason why a process isn't working.

Fishbone diagrams can be drawn by hand or created using a variety of digital diagramming tools, such as Microsoft Vision, Google Diagram or Creately.
