In this module, Dr. Bill Bailey will cover root cause analysis, which includes the 7-step model, counter measure, and "single-minute exchange of die" (SMED). This module also begins with a Yellow Belt Refresher Area, since some learners may have entered this course without having taken the previous belt material. This refresher area does not serve as a "replacement" for taking the material. It is only a "patch" for those who already have some knowledge of six sigma, but find the yellow belt specialization to be too introductory for their current situation. If you find yourself struggling with the green belt material in this course, it is highly recommended that you travel through the yellow belt specialization before attempting the green belt content.
