Which of the following are possibilities of how the production of final products can be made more resilient when a massive shock like COVID-19 hits their operations? Multiple select question. Move production back to country where the firm is headquartered or the country in which most of the final product is sold.

Choose a single foreign location for each step in the supply chain to reduce the risk of relying on many foreign locations for that step. Develop flexible design of the product so that the product can be produced using some other component in place of any component that is temporarily in short supply
