What does NOT point to an abnormality when analyzing a control chart?
- Points between the control limits in a control chart do not represent abnormalities. Control charts are graphical displays of the results of processes over time. They help determine if a process is in control. All points between the lower and upper control limits are indicative of the process being in control. These do not indicate any abnormality.
Runs are a series of points on one side of the central line. A run of up to six points is normal. Only a run greater than seven points could be a possible abnormality.
Five or six consecutive points going in the same direction indicate a trend. Because trends show a continued rise of all in a series of points, it points to abnormalities.
Points that lie outside the upper and the lower control limits indicate that the process is out of control or unstable, and points to an abnormality.
The following is an example of a control chart for a project that is in control:
