The category of forecast variation that refers to general or inherent variability is common cause. This type of variation is consistent and predictable within a process. It represents the natural fluctuations that occur in any system, which can stem from common sources or factors that are inherent to the process itself. Common cause variation is typically stable over time and can be anticipated based on historical data.

In logistics and transportation, recognizing common cause variation is crucial. It helps in understanding normal operational performance and aids in process improvement initiatives. For example, if a company experiences variability in delivery times due to traffic patterns or seasonal demand, this is considered common cause variation, and strategies can be developed to manage or mitigate these effects.

The other categories of variation, such as special cause, refer to specific, identifiable factors that are not inherent to the system and which can lead to anomalies in performance. Random cause variation pertains to fluctuations that arise from unpredictable factors that do not follow a discernible pattern. Predictable cause variation implies that there are identifiable patterns in the data that can be anticipated, but this is not as uniformly applicable as common cause variation in outlining general variability.
