The automotive industry has traditionally been highly important to the global economy both in terms of the goods that it provides and the jobs that it allows for. It directly contributed 3.6 percent to the GDP of the United States at the time of the financial bailout and, according to the United States Bureau of Labor Statistics, currently employs around 3,470,000 people nationwide.
The primary focus of the auto industry is the production, development, sale, and distribution of motor vehicles, and this task is accomplished using a vast infrastructure that encompasses three main layers and has a large variety of different functions.
The bottom layer consists of all of the parts of the automotive companies relating to the production and development of motor vehicles. The primary purpose of this layer is to ensure that motor vehicles are consistently being produced and that they possess the right qualities to be sold in the market. This layer includes the factories used to build motor vehicles, and the labratories used for research and development of them.
The top layer of the industry is the consumer, who is eventually the recipient of the vehicles produced at the bottom layer. The purpose of this layer is to provide funding back to the top layer so that it can perform its job with more effectiveness. This layer is very broad and could inculde anyone who directly purchases a vehicle from an automotive company.
The final layer consists of all the parts of the automotive companies relating to the sales and distribution of motor vehicles. The primary function of this layer is to serve as middleware and connect the top and bottom layers in order to ensure that the fully produced motor vehicles are distributed amongst the consumers and that the money from the consumers is distributed amongst the company. This layer has a few different components including salesmen, marketers, and dealers.
