In this video, I'm going to share some control charting rules that will help you improve your data tracking and analysis. By following these rules, you'll be able to identify and correct any process problems early on in the process.
SPC is an important tool that can help you optimize your processes and get accurate results. By following these control charting rules, you'll be able to get accurate data analysis and make necessary changes to your process. So make sure to watch this video and learn all about SPC control charting rules!
This video discusses in depth the eight control charting rules known as Nelson's rules. I go over the history of control charting rules including Walter Shewhart and the Western Electric Rules. Then I go into detail on how to interpret each rule, some control charting examples, and some general considerations and concepts to keep in mind.
