It is said that a chain is only as strong as the weakest link in it. There are many facets of a supply chain and just one weakness can hurt the entire chain. One of the best run companies in the world, Apple, is renowned for its supply chain.

He has been credited with their massively increased efficiency and profitability, so there are plenty of reasons why other businesses should pay attention to how they run their operations.
