Before we can solve a problem, we need to determine its root cause. Frequently, we focus on the most apparent reason and then wonder why the problem persists. The "5 Whys" QM method counters this phenomenon by guiding us to the crux of the problem.

In this online training course, you will learn the results-oriented "5 Whys" analysis technique to quickly and reliably identify the root cause of a problem.

This course illustrates how to employ the "5 Whys" technique whenever and wherever convenient. You can test your knowledge by completing the quiz offered at the end of the course.
