Course Description

The 8D Process, which contains the tools and strategies of Root Cause Analysis, was invented by the Ford Motor Company in the 1980's as a universal problem-solving method.

To create such a method, Ford combined existing best practices from luminaries such as Shewhart, Deming and Juran with their experiences in the US Auto Market competing against foreign imports. The resulting 8D process became the standard problem-solving tool across Ford's Product design and manufacturing engineering team. But because of its systematic effectiveness, it soon spread to other departments, other divisions and ultimately other industries.

Today, a manufacturing professional with a solid understanding of the principles and tools taught in this class will be able to effectively solve a range of problems. And it is the solving of increasingly complex problems that lead to career advancements and new doors of opportunity.

This course, "Root Cause Analysis and the 8D Corrective Action Process" will show you:

  • How to assemble an effective problem definition.

  • The value of creating a cross-functional team.

  • How to develop interim containment solutions to shield your customer from receiving further defects.

  • The connection between an organization's traceability system and the RCA and 8D process.

  • An overview of process modeling tools such as the process flow diagram and the value stream map as means of graphically depicting the process and subsequent improvements to it.

  • How to use popular quality tools to find root cause such as pareto analysis, interviewing, the Ishikawa diagram, the concentration diagram, 5 Why analysis and much more.

  • How to use analytical tools such as capability analysis, regression analysis, measurement systems analysis, control charting and more to further clarify your root causes and develop potential corrective actions.

  • How to generate and prioritize corrective action ideas.

  • A sampling of corrective action strategies such as andon, shifting the process mean, correlating process to product variables, standardizing work instructions, poke yoke, automated inspection and much more.

  • How to verify your corrective activities for effectiveness.

  • How to develop parallel and preventive activities to maximize the impact of your problem solutions.

  • How and why to acknowledge your team's success.

I like how informative it is, but I think it would be better if it didn’t focus entirely on the manufacturing industry. It would be helpful to include examples from other industries as well, so we can capture the interest of learners from different fields and give them a broader perspective.

By Mohamed Helmy on 8/12/2026

The course was for me to see how deeply I understand the field. I would say I gained about 10% more than what I already knew, which is more than what I was expecting. Thanks for everything :)

By Linda Williamson on 7/27/2026

It helps explain all the different methods in a short broken up format. Even though I passed the CQE, there has been very little opportunities at my current job to put it to practice so I have to continue brushing up

By Francesca Martirano on 6/30/2026

Thanks for the thoughtful, in-depth breakdown of 8D and the many RCA tools. Some I am familiar with but the regression analysis was very intriguing.

By Martie Calldo on 6/30/2026

Thank you it broaden my thinking towards Process Capability Analysis which I never included before. Will LOVE to look more into it to enable me to see how we can use it.

By Denis Enrique Martinez Villasmil on 5/17/2026

This is a fenomenal practical and rich course which help to create a solid foundation in 8D and root cause analysis. It can be right away implemented in our application.

By Burutira Mark on 4/20/2026

Wonderful pacing, the Instructor is devoted to making sure that the learners gain a fundamental understanding of the concepts laid out

By Claudia Herrera Cano on 1/31/2026

Yes! I am working in QA department, and we have some findings from and external audit. This course is giving me some ideas on how to manage it

By Barun Kumar on 12/26/2025

Very well explained - 8D method of Problem solving !! During the journey also got opportunity to revisit my knowledge on process capability and control charts.

By Anonymized User on 12/8/2025

Good but instead of lot of theory realtime example based course will be better. Instead of learning we have to apply it in actual work

By Sushma Gundala on 11/22/2020

Was very good
