Level 1 Metrics are primary, high level measures that may cross multiple SCOR processes.
They do not necessarily relate to a SCOR Level 1 process (Plan-Source-Make-Deliver-Return).
There is hierarchy among the metrics in different levels.
Level 1 Metrics are created from lower level calculations (Level 2 metrics)
Level 2 Metrics:
Associated with a narrower subset of processes.
Example:
Metric related with Delivery Performance: Total number of products delivered on time and in full based on a commit date.
Metric related with Production: Ratio Of Actual To Theoretical Cycle Time
