Here are the steps I followed to produce the result. 1. I created a
Although in Six Sigma study, we usually read Control chart in the Control phase. However, a control chart is being used at the initial stage to see the process behavior or to see the Voice of Process (VoP). If our process is stable its’s only then we should think about running the project. Else, at first, we should make the process stable. Control Chart A control chart, sometimes referred to as a process behavior chart by the Dr. Donald Wheeler, or Shewhart Charts by some practitioners named after Walter Shewhart. The control chart is meant to separate common cause variation from assignable-cause variation. A control chart is useful in knowing when to act, and when to leave the process alone. Control Chart is a graphical tool that helps determine if a process is “in control or not”. A control chart has three zones and is graphically represented as: Six Sigma Control Chart Zones.
