Cause and Effect Diagram - 7 Quality Tools

This video on the Cause and Effect Diagram is part of the 7 Quality Tools series. In this 5:26 minute video, you will learn the following:

What is the Cause and Effect Diagram?
When should you use it?
How to create one.

We also cover some history and explain how the Cause and Effect Diagram is also the Ishikawa Diagram and how Root Cause Analysis is, at its core, the purpose of the Cause and Effect Diagram.
