A3 Training & Certificate


Learn the basics of the A3 and build your problem-solving muscles.

Category: Tags: ,


What Is an A3?

On a literal level, A3 refers to a ledger size (11×17) piece of paper. But in the Lean Six Sigma world, it is a tool to help see the thinking behind the problem-solving. Don’t mistake A3s as a document to be completed after the problem is solved. It’s important to use the A3 while working through the problem.

The practice of using A3s forces project teams to focus their efforts. At the same time, A3s make it easier for a leader or coach to review a problem solver’s work. A3s become valuable coaching tools since leaders can see and provide feedback on the problem solver’s thought process.

good tool to create a high level overview. Had trouble getting through the quiz - seeing final results would be helpful.

Easy to understand; straightforward

by Aaron Alderson on A3 Training & Certificate

The training course was fantastic and helped me understand how to tackle an A3. The only place i felt was lacking was the quiz. It was very general and could you more specific questions. I didn't feel like i had to review the material during the quiz.4
