Answer: Radial Autos should pursue Backward Integration.
Explanation: Backward integration is the process in which a company purchases or internally produces segments of its own supply chain. Simply put, it is when a company acquires and controls certain inputs that could be utilized in the process of manufacturing its products or services.
This is a competitive strategy, because it lowers the cost of production and this will reflect in the price of the final product.
This is the strategy that Radial Autos should pursue in order to lower cost and reduce risk in interruption of the supply component, because in adopting this strategy, they will have total control over the inputs they use in production.
