My biggest interaction with supply chains is through the use of money creating demand and causing growth.
The challenge i face in this sector is that i interact with a supply chain through the purchasing of good or services and am often unaware of the practices and impacts of the supply chain as a whole.
My second largest interaction is at work, i lead the planing department for a group of medicines.
Finally i would say my choice of what i view on line is often tracked by companies and used as a lead indicator for demand, i am conscious of the impact this has.
