can and should be changed much more frequently
(almost every month in the beginning, becoming
more stable after a number or months). The report
uses clusters of metrics and hierarchical levels (Fig.
5). The selection of metrics, the scope of the clusters,
the structure of the hierarchical levels, and the
presentation of the reports are all aspects that
needed to be reviewed frequently, parallel to using
the actual metrics for managing the supply chain.
In short, the approach has developed into (1) the
creation of a metrics dictionary, combined with (2)
an overview of initiatives, leading to (3) a draft
version of the scorecards and (4) explicit procedures
for using and updating the metrics dictionary.
