Supply chain – DFSS: The process of material flow from suppliers to manufacturers becomes the part of a company’s external supply chain. In the 80’s organizations were looking for ways and means for improving their process efficiency, and for that purpose they revamped their internal processes. After they had succeeded in making their all internal processes efficient, businesses around the globe were required to make their external processes efficient in a way that time could be reduced and further money needed to market and distribute products should decrease. For this, they needed to redefine their relationship with all their suppliers, retailers, distributers, and customers. Those forms the part of their external supply chain. An effective relationship with all these entities increased the organizations’ need for information sharing and making it mutually dependent. This has caused a paradigm shift in competition of organizations from manufacturer VS manufacturer to supply chain VS supply chain.
