Read the scenario below and answer the question that follows: Checkers Holdings A few years ago, Checkers decided to streamline its supply chain, and upgrade its operations to ultimately drive down its costs. This is because Checkers wanted to use its supply chain as part of its global competitive advantage strategy, and create more sustainability for the future. Checkers trucks operate 24 hours a day, 7 days a week, to ensure maximum availability of goods, at all times. A newly introduced scheduling operations system optimises store deliveries and reduces the number of trucks needed at once on the roads. In this way, Checkers addresses its carbon footprint, saves costs and reduces congestion on all fronts of its operations. The group has invested in an extended decentralised distribution network with three strategically positioned warehouses in different geographical areas. These warehouses, the size of 105 rugby fields, hold stock from 4744 suppliers, and are the point of origin for shipping stock to 2400 of their stores in 15 African countries. This innovation presents Checkers with the opportunity to redesign its retail stores to make optimal use of retail space, by dedicating the minimum space to storage and more to trading space. With reference to geographical specialisation, in your own words, explain how large retailers, such as Checkers, address the issue of supply and demand through their supply chain management strategy.
