The analysis of performance of metrics from level 1 through 3 is referred to as decomposition. Decomposition help identify the processes that need to be studied further. (Processes are linked to level 1 and level 2 metrics.)
Many metrics in the SCOR model are hierarchical, just as the process elements are hierarchical. Level 1 metrics are created from lower level calculations. Level 2 metrics are generally associated with a narrower subset of processes for example, Delivery Performance is calculated as the total number of products delivered on time and in full based on a commit date. Additionally, metrics (diagnostics) are used to diagnose variations in performance against plan. For example, an organization may wish to examine the correlation between the request date and commit date.
Supply chain council recommends that supply chain scorecards contain at least one metric for each performance attribute to ensure balanced decision making and governance.
