Interested in learning more about data analytics, data science and machine learning applications in the engineering field? Explore my previous articles by visiting my Medium profile. Measurement means are plotted on the X-bar chart and. You can also email me directly at and find me on LinkedIn. Measurement systern's stability is measured using control charts, typically X-bar and R-charts. If you found this article useful, feel welcome to download my personal code on GitHub. Once again, I invite you to continue discovering the amazing stuff you can perform using R as an industrial engineer. These control charts can be used if you need to assess system stability, if. As you might have noticed, just with few lines of code we were able to construct quality control charts and get significant information to be used during Lean Six Sigma and DMAIC projects for process improvement. X-Bar and R-Charts are typically used when the subgroup size lies between 2 and 10. We have gone through one of the many industrial engineering applications that R and the qcc package have to offer. Interested in learning more about what this capability estimates mean? Go to the ASQ (American Society for Quality) website by clicking here. The process capability analysis summary chart above provides significant information and capability estimates for the engineer to interpret the process ability to meet the given specifications.
