On June 1st, 2009, General Motors (hereafter GM) declared itself bankrupt, triggering the biggest bankruptcy in history. The direct cause of the bankruptcy was a global financial crisis in 2008. But we need to go back in time.probably to the Chicken tax in the 1960s and the oil crisis in the 1970s-- to find the real reasons for GM’s gradual collapse. The fall of GM is probably one of the most important events in business history of last 100 years. The purpose of this case is to describe the rise and decline of GM, once the biggest company of all in the world, and the biggest automaker during the period from the early 20th century to 2006,while focusing on a few historic events. Those events are Alfred Sloan's revolution, the Chicken tax and the oil crises in the 1960s and 1970s, Saturn project, and collapse of GM after 2000. These events surprisingly well summarize the rise and declining process of GM. Two of those events, the Chicken tax and the oil crises occurred outside GM, while other events such as Sloan's revolution and Saturn project occurred within the company. While these events occurred with significant intervals, they are somehow connected with each other. For example, the oil crises in the 1970s were an warning signal to GM that had made primarily fuel inefficient large sedans and trucks by that time, and Saturn project was a GM's reaction to the warning signal. This study uses qualitative case methods, using numerous articles on GM, the autobiography and memoir of Alfred Sloan and Bob Lutz, and studies of such scholars as Alfred Chandler. After careful analyses, it is concluded that GM's fail was due to many reasons, including organizational inertia, lack of service mind, and implementation of poorly formulated strategies.
