5 Whys & Fishbone Diagram Training & Certificate


Learn the basics of the 5 Whys & Fishbone Diagram and build your problem-solving muscles.


What Are the 5 Whys?

5 Whys is a simple but effective method of analyzing and solving problems by asking “why” five times, or as many times as needed, in order to move past symptoms and determine root cause. This approach is used in tandem with Cause & Effect or Fishbone diagrams.

What Is a Fishbone (Cause & Effect) Diagram?

The Fishbone (or Cause & Effect) Diagram is a structured brainstorming tool designed to assist an improvement team in listing potential causes of a specific effect. Its name derives from its resemblance to the bones of a fish. It is also known as an Ishikawa Diagram, for its creator. This tool is used in tandem with The 5 Whys.

Good tool to pull in key members of the process and quickly identify potential issues.

This was a completely new topic to me and the course helped me to gain a useful understanding of it.

Got some great new information, but some of the test questions were not covered clearly in the training.

I enjoyed taking this course on a specific facet of Lean Six Sigma. I like how this organization has broken out specific aspects for more study. I highly recommend it.

Easy to understand and helpful.

Very helpful and educational.
