In June of this year, we will publish our fifth analysis of the Supply Chains to Admire. The Supply Chains to Admire methodology celebrates companies that outperform their peer group while driving a faster rate of improvement. Improvement is easier to say than to measure. To create the Supply Chains to Admire, we developed a methodology to measure improvement. It is defined by the Supply Chain Index. To help companies better understand the Supply Chain Index and relative rates of change within an industry, here we dedicate an entire report to the methodology underlying the Index.
