The individual organisation or company that controls a part of
this large total supply chain from‘‘wheat to bread’’or‘‘ore to cars’’
has a supply chain of its own with different processes and activi-
ties that produce value to customers from their suppliers.Large
companies or groups can have substantial supply chains with
separate factories delivering to the factory that,in turn,delivers
to the external customer.We study and discuss the supply chain of
the individual organisation,not only the focal firm but the supply
chains the organisation,company or group can control,keep track
of and design,from external supplier to external customer.
