The Covid-19 pandemic has created logistical nightmares, many of which affected product flow and threw supply chain management into crisis. The pandemic exposed myriad vulnerabilities in supply chains. Companies saw their products trapped upstream due to breakdowns in the chain. Some products were unavailable, others no longer in demand at all. Food spoiled in warehouses and trucks, while grocery store shelves were bare, and warehouses were empty or unsafe. Many companies found themselves unable to handle increased demand for products, necessity for new packaging, safety issues, and so on.
