Control Chart Release For Free

Look for "out-of-control signals" on the control chart. When one is identified, mark it on the chart and investigate the cause. Document how you investigated, what you learned, the cause and how it was corrected.

If the data points fall within the control limits, the process is in control and no action is needed. If the data points fall outside the control limits, or show a non-random pattern, the process is out of control and corrective action is needed.

When points on a control chart move outside the upper or lower control limit, the process is said to be ?out of control.? As long as the points are within control limits, the process is ?in control.? But, what does an out of control process indicate? Many believe that an out of control process produces defective parts.

A Control Chart Indicates a Process is Out of Control When: Six consecutive points, increasing or decreasing. Fourteen consecutive points alternating up and down. One or more points outside the control limits.

Actually, an out of control process indicates the presence of non-random variation. Non-random variation is caused by definite, specific causes that are called assignable causes. These assignable causes make the process go out of control or become statistically unstable.

If the process is in control (and the process statistic is normal), 99.7300% of all the points will fall between the control limits. Any observations outside the limits, or systematic patterns within, suggest the introduction of a new (and likely unanticipated) source of variation, known as a special-cause variation.

Points Beyond the Control Limits Action should be taken to find the special cause and permanently remove it from the process. If there is a point beyond the control limits, there is no need to apply the other tests for out of control situations.

An out-of-control process has points falling outside the control limits or non-random patterns of points (called special-cause variation). If the process is in-control, no corrections or changes to the process are needed.

A Control Chart helps you identify whether data from the current sprint can be used to determine future performance. The less variance in the cycle time of an issue, the higher the confidence in using the mean (or median) as an indication of future performance.
