Hi there. My name is Ron Pereira and I'd like to officially welcome you to this first overview module of the Gemba Academy 7 QC tools course.By the end of this module you'll know what quality control is, you'll understand the benefits of quality control, and you'll know what the QC tools are. You'll also begin to see how the 7 QC tools can help your organization improve no matter what type of work you do.To be sure, you don't have to manufacture widgets to practice quality control as we'll learn throughout the rest of this course.
