The given line chart illustrates the amount of time spent while producing a single car from four different companies in the United States. The manufacturers are Nissan, Dalmler, Chrysler, General Motors, and Ford from 1998 to 2002. Unites are measured in hours per vehicle.
Overall, it is clear from the graph that all companies’s time of producing one vehicle sharply decreased over time. Nissan, however, experienced a rapid pace of minimizing the time of producing a car.
General Motors had a stable decline in production time over the years, starting from 1998. On the other hand, Dalmler Chrysler’ production time dropped at the beginning to 1999, remained stable by 2001, and then dipped below significantly.
Nevertheless, Nissan, as mentioned before, had a dramatic fall to 2000, saving approximately 20 hours of the manufacturing process. Moreover, this company kept reducing the time of the manufacturing process by 3 hours in 2002. Meanwhile, Ford initiated by almost 25 hours, began to increase the time of the process of making a car to 27 hours, and dropped slightly by roughly 2 hours to reach 25 hours only of the production period in 2002.
