Statistical process control charts (run and Shewhart control charts) are a good way of between random and non-random variation using four simple rules. improvement: the process of choosing, defining, collecting, analysing and reviewing data. Part 4. Run chart and statistical process control chart rules in practice. Apply the Western Electric rules to the following control chart. The warning limits are shown as dotted lines.

Control Charts & The Balanced Scorecard: 5 Rules. Control charts can be used as part of the Balanced Scorecard approach to account for an acceptable range or variation of performance. If you choose to do this, there are five key quality control rules to keep in mind when considering using control charts at your organization:
General Rules for Interpretation of Control Charts The primary use of control charts is to help in determining whether or not the process in question is stable. In this sense, “stable” refers to a state of statistical control, a condition which exists when the process is affected by only random variation—that is, variation that’s inherent in the process and not caused by unusual influences. The control chart is a graph used to study how a process changes over time. Data are plotted in time order. A control chart always has a central line for the average, an upper line for the upper control limit, and a lower line for the lower control limit. These lines are determined from historical data.
Shewhart control chart rules. Tests for special-cause variation determine when a process needs further investigation. There are various tests that can be used in
The Control Chart is a graph used to study how a process changes over time with demonstrates how run rules and a Shewhart control chart can be used as an Shewhart control chart rules. Tests for special-cause variation determine when a process needs further investigation. There are various tests that can be used in Rule 1 One point is more than 3 standard deviations from the mean. One sample (two shown in this case) is grossly out of control. Rule 2 Nine (or more)
The rule set should be clearly stated.) Any point outside the control limits; A Run of 7 Points all above or all below the March 2016 Control charts are a valuable tool for monitoring process performance. However, you have to be able to interpret the control chart for it to be of any Control chart rules are used to determine if a process is stable and predictable. Control chart rules can vary slightly by industry.
