A project team evaluated the performance of a new reporting system and the quantity of queries to be processed during predetermined time stamps. Which of the following is the current status of the process?
A.
Based on the rule of seven, the process is under control.
B.
The amount of data is insufficient to determine if quality is low.
C.
The process is out of control and should be revised.
D.
The goal should be adjusted since most of the data points are close to the lower limit.
C. On a control chart, when seven consecutive data points fall on the same side of the mean, either above or below, the process is said to be out of control and in need of adjustment. All the seven points may be within the control limits.
It's been about seven hours since anything's been outside of the limits, but the data points are mostly above the mean. Rule of sevens says seven points fall on one side of the mean, it's an assignable cause. So it's out of control.
