One control chart is I-chart, which is established for ‘individual runs’.The moving ranges, MR (difference between 2 consecutive points) are also calculated and a chart is kept for MR.I-chart is a measure of ‘process mean’, MR is a measure for process variation.Both charts are based on 3-Sigma limits. Control charts are a key tool for Six Sigma DMAIC projects and for process management. Individuals charts are the most commonly used, but many types of control charts are available and it is best to use the specific chart type designed for use with the type of data you have. Six Sigma DMAIC – Control Phase. The last phase of Six Sigma’s DMAIC model is the Control phase. The focus of this stage is to make sure that the action item created in the Improve phase is well-implemented and maintained. Several tools are used in this stage to make sure that variables are within its limits. Control Phase of a Six Sigma DMAIC project.

Elements of a Control Chart. A control chart consists of: A central line, An upper control limit, A lower control limit, and; Process values plotted on the chart. If all process values are plotted within the upper and lower control limits and no particular tendency is noted, the process is referred to as in control. 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. The primary SPC tool for Six Sigma is the control chart — a graphical tracking of a process input or an output over time. In the control chart, these tracked measurements are visually compared to decision limits calculated from probabilities of the actual process performance.

"Six Sigma quality" is a term generally used to indicate a process is well controlled (within process limits ±3s from the center line in a control chart, and requirements/tolerance limits ±6s from the center line).

In a Six Sigma project, we can use a Control Chart at the starting of the project as well as at the Improve phase to implement some necessary improvement steps and adopt some corrective measures to keep the project under control. Stabilize your process | Sign up for a Six Sigma course now! Whereas, Sigma in the control charts is about the capability of your PROCESS. You start with the average (or median, mode, and etc.,) which is a measure that represents the standard deviation.

26 Oct 2018 A Control Chart is also known as the Shewhart chart since it was introduced by Walter A Shewhart. We can also call it as process behavior chart.
