Learn how to interpret control charts and distinguish between common and special causes when conducting Six Sigma projects.
- In Six Sigma Green Belt training…you were introduced to SPC charts,…in a number of videos.…Now let's talk about the use of…Minitab for SPC charts.…As a black belt you will be expected to know…how to develop and use SPC charts.…And to guide others in using them.…Knowing about SPC charts is not the same as…having a hands on experience in developing…and analyzing SPC charts.…With that in mind, let's practice this…using Minitab.…
To get started go to your exercise files…and download SPC data dot M T W…and open it.…Look at the column length…and essentially it's continuous data.…Individual values.…So the chart to use would be the RE chart…or individual's chart.…Let's plot that.…Go up to stat.…Control charts.…Chose individual chart and plot length.…Go to I chart options to specify…what tests you want to run.…You want to test for all special causes.…
Okay.…And okay.…You have the control limits, UCL.…Lower control limits, LCL.…X bar is the center line, the mean…and Minitab indicates that we have…out of control points…in this red dots.…
