The automobile industry is going through a dramatic change as electric vehicles (EVs) rapidly gain in popularity. Two companies in particular have dominated the EV market over the last decade: Tesla and Nissan. However, Nissan, despite its global presence and production capability, has lost significant market share to Tesla. Going forward, the company's operational and strategic decisions are vital to its success in the EV market. Tesla, on the other hand, has aggressively gained market share over the past decade, becoming the most dominant player in the EV market. The company has taken unique approaches for its supply and operations. Will Tesla be able to scale its operations to meet the rapidly increasing demand for EVs? With other large global automakers now turning their attention toward the EV market, will Tesla and Nissan be able to retain their market shares? This case discusses the approaches taken by Nissan and Tesla with their operational, supply chain, and marketing strategies to become leading EV manufacturers. It also sets the stage for the discussion on whether or not their current approaches will be optimal going forward.

N95 masks are an important aspect in the fight to prevent the spread of COVID-19 due to the virus's contagious nature. Coronavirus is a flu disease. It affects the respiratory tract of a person's body and causes difficulties in breathing. COVID-19 is a new strain of coronavirus that had not been previously identified in humans. Most people infected with the COVID-19 virus who are symptomatic experience mild to moderate respiratory illness, fever, and fatigue, and recover without needing to be hospitalized. However, there are cases wherein people are asymptomatic (i.e., not showing any symptoms) but still test positive for the virus and complicate attempts to stop its spread. This case introduces students to critical issues that occurred in the supply chain for N95 masks during the global pandemic. While many students will be familiar with the fact that supply chain disruptions occurred during the crisis, many will not know the specific details or why these disruptions occurred. The case can be used to illustrate the fundamental operational issues that occurred throughout the N95 masks' supply chain, discuss where improvements should be made, and emphasize the concept of supply chain resiliency.
