The line graph indicates statistical data related to the number of hours required to produce one vehicle by four companies between 1999 and 2007
Looking into the line graph in detail, in 1999, 32 hours were required to produce one vehicle by Audi, which was the highest level compared to other companies. However, this number experienced a steady decline, dropping to around 20 hours by 2006. On the other hand, Mercedes began with roughly 25 hours and maintained this level until 2002, after which its production time slightly increased, aligning with Audi’s at about 27 hours in 2002.
Moving onto the other categories, Volvo preserved a constant hour throughout the years at 22 hours from 1999 to 2006. Meanwhile, beginning at 21 hours, Nissan experienced fluctuation throughout the years.
Overall, it is apparent that the figures demonstrate differences in almost all categories, but the most distinctive feature is that Nissan produced one vehicle at a stable hour throughout the years.
