Define process variation:
The spread of process output over time. There is variation in every process, and all variation is caused. The causes are of two types - special or common. A process can have both types of variation at the same time or only common cause variation.
Different types of Process Variation:
Variation that is characterized by a stable and consistent pattern of variation over time. This type of variation will be random in nature and will be exhibited by a uniform fluctuation about a constant level.
Variation that is characterized by a pattern of variation that changes over time and hence is unpredictable. This type of variation will typically contain some structure.
This concept of controlled/uncontrolled variation is important in determining if a process is stable. A process is deemed stable if it runs in a consistent and predictable manner. This means that ...
