Statistical Process Control (SPC) helps ensure that the solution created is maintained over time. By using these tools, your process can remain in control.
Statistical Process Control and Stability of Process
Predictable process vs unpredictable.
Predictable: variation coming from common cause variation – or variation inherent to the environment of the process.
Unpredictable: special cause variation exists.
