Fixed it.
There is a lot of truth to this.
One of the facilities I run had a similar problem. Our “corporate” supply chain team wanted to shift one of our volume product to a Major supplier in Mexico they were looking to further develop.
The problem came when I pushed backed and wanted to see the total landed cost and the details of the costs in Mexico. While Mexico’s hourly labor rate was slightly below the TN facility, their overhead rate was actually higher. The net result was that TN was $0.19 cheaper per labor hour, and that didn’t include the shipping costs, or any potential risks.
