Individuals and Moving Range (I-MR) Charts are among the most useful Six Sigma and quality management tools. We call them Process Behavior Charts, while others call them Control Charts. Their fundamental job is to detect process instability. If there is no instability, then the process is stable and predictable, and is likely to work again tomorrow. • Three of the common errors and myths associated with Process Behavior Charts are discussed: Shewhart did not assume normality when he created the first Control Charts, there is no need to use Xbar and R charts to ensure normality, and it is not required that the Moving Range chart be in control before interpreting the Individuals chart. • ----- • Links: • PMG Results Website: https://www.pmgresults.com/ • Have a Question? https://www.pmgresutls.com/contact/ • QuikSigma Software Perpetual Licencse: http://bit.ly/2mxagk2 • Basic Green Belt Certification: http://bit.ly/2mx5Ycw • Advanced Green Belt Certification: http://bit.ly/2nhg8Os • Black Belt Certification: http://bit.ly/2mV6Z0z • ----- • Individuals and Moving Range charts 0:27 • Detects instability 0:40 • No rule violation = stable and predictable 0:46 • Rule violations = unstable 1:02 • Accounts receivable example 1:17 • Compare subgroups of data, test measurement systems 1:47 • Normal distribution not required 2:09 • Xbar and R charts useful, require more skill 2:34 • Not required that the Moving Range chart be in control 3:06 • Abundant information, insightful tool 3:38
