Free Six Sigma Green Belt Course

The free Six Sigma Green Belt course focuses on how you decide whether evidence supports a process change. You start by defining the problem and the result the customer needs. Measurement system analysis then helps you question whether the data is dependable enough to use. Process capability and variation give you further ways to describe how the process performs against its requirements.

As you move into analysis, the course introduces hypothesis testing and the difference between correlation and causation. These ideas help you examine an explanation before treating it as the cause of a problem. Improvement lessons cover choosing solutions and running a pilot, followed by control plans and response rules. You also study how to hand ownership back to the process team so a project has a practical route from its first charter to sustained day-to-day use.
