The line graph illustrates the time spent on vehicle production by four American car manufacturers between 1998 and 2002. Overall, it can be seen that the majority of car producers experienced a decline, while only Ford saw a slight increase.
In the years 1998 to 2000, the vehicle production time for most car manufacturers, except Ford, decreased steadily. Nissan’s production time showed the most significant reduction, dropping from around 37 hours per vehicle in 1998 to about 24 hours in 2000. Similarly, Daimler Chrysler (DC) declined moderately by 2 hours from 34 hours to 30 hours. General Motors (GM) also saw a steady decrease, falling from 32 hours to 30 hours during the period. In contrast, Ford had a minimal rise, increasing from approximately 25 to 26 hours over these years.
From 2000 to 2002, there was a slight change in the production time of some manufacturers. Nissan’s figure decreased gradually by around 3 hours to 21 hours, and General Motors (GM) still decreased continuously to 24 hours at the end of the period. However, Daimler Chrysler (DC) remained stable for the next one year, but subsequently dropped to 28 hours in 2002. Conversely, Ford showed a small increase, only rising by 1 hour in 2002.
