What are the essential organs that keep a supply chain running? Ken Fordyce answers this question in an article at EBN, where he outlines the three primary activities of supply chain planning (SCP) and two secondary activities.

The ‘analytics workbench’ is where you use analytics to develop insight into SCP or sales and operations planning (S&OP).
