Control Charts are a simple but highly effective tool for monitoring and improving process performance over time because they help Six Sigma teams to observe and analyze venation. The three basic components of any control chart are a center-line, upper and lower statistically determined control limits, and performance data plotted over time. In Six Sigma initiatives, you can make control charts for attribute data. Attribute data is data that can’t fit into a continuous scale but instead is chunked into distinct buckets, like small/medium/large, pass/fail, acceptable/not acceptable, and so on. Although monitoring and controlling products, services, and processes with more sensitive continuous data is preferable, sometimes Control charts are an essential tool of the Lean Six Sigma methodology. After the upper and the lower control levels are inserted, a control chart is generated to map the changes. It is generally a line chart that displays the changes in the variables in a given period.

Six Sigma DMAIC Process - Control Phase - Control Chart Selection Points to keep in mind while selecting a control charts: Continuous Data: For continuous data we can measure the average and the variation, thus X bar &R (Range) or X bar and S (Standard deviation) can be used. 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.
