A supply chain is a specific order of steps taken by a company to get its product or service to the public. Supply chain management involves managing the flows of goods and services by linking production, shipment, and distribution. Two of the primary goals for businesses using supply chain management are to streamline costs and increase the speed of getting products to consumers. Each year, Gartner, a global research firm, publishes its “Supply Chain Top 25”, identifying the companies that it believes best demonstrate leadership in applying supply chain management to drive business results. The four companies in the 2018 “Master’s” category, which identifies companies with sustained leadership for the past 10 years, are Apple, Procter & Gamble, Amazon, and McDonald’s. Do some research on one of these four companies and describe what supply chain practices the company has utilized, and how those practices have affected the company’s production, efficiency, competitiveness, and profitability.
