What is the total supply chain cost?

Could you please elaborate on what you mean by "total supply chain cost"? Are you referring to the cumulative expenses incurred throughout the entire production and distribution process of a particular product or service, including raw material sourcing, manufacturing, logistics, warehousing, and final delivery to the end-consumer? If so, it's essential to note that calculating the total supply chain cost can be quite complex, as it involves various factors such as labor costs, transportation expenses, overhead costs, and other operational expenses. Could you provide more context or specify which industry or product you're referring to, so I can give a more accurate answer?
