No firm is an island: Why buyers should probe a supplier’s network
For any shopper who noticed how the price of hamburger and lettuce jumped after gas prices soared last year, this should come as no surprise: Buyers eventually feel the pinch when their suppliers’ expenses surge. The reason? Buyers and sellers operate within networks that exceed the one-on-one, buyer-seller bond. That’s why Thomas Choi, a professor of supply chain management at the W. P. Carey School of Business, thinks supply chain professionals would be wise to look beyond the supplier to its supply network. Without it, he argues, buyers are not examining all the factors affecting the strength and reliability of the suppliers they choose. Such shortsightedness leaves buyers vulnerable to supply troubles and missed opportunities.
