You plan to collect historical data for the default indicator "Number of open and overdue incidents". Which breakdown should be excluded from the historical data collection job?

When collecting historical data for the default indicator "Number of open and overdue incidents," it is essential to focus on breakdowns that contribute meaningful insights to the analysis. The breakdown that should be excluded is the state because the state of an incident (for instance, open, closed, or resolved) is a dynamic variable that often changes over time. Including the state in historical data could lead to misleading trends since it reflects the current status rather than providing insight into the overall historical context or performance.

In contrast, breakdowns such as Category, Age, and Priority are static or can provide insights that are more valuable over time. The Category indicates the type of incident, Age measures the time since the incident was created, and Priority shows the importance assigned to the incident. These elements can often help in understanding long-term trends and performance across various segments. Therefore, by excluding the state, you're ensuring that the historical data collected is not skewed by transient conditions and better reflects the overall trends in incident management.
