The line graph gives data on the number of hours spent on vehicle manufacturing in the USA for four distinct car brands, within a span of 5 years, starting from 1998. Overall, Daimier Chrysler was by far the most time-consuming brand to manufacture for the majority of the period, whereas Nissan saw the largest decrease in production time. Notably, Ford, which initially required the fewest hours, showed a significant growth trend and surpassed both Nissan and General motors by the end of the timeframe.
Delving into the details, in 1998, Daimier Chrysler (DC) and Nissan took substantial hours to be produced, stood at 34 hours and 32 hours respectively. Over the following years, however, turned out to be quite negative for both of them. As for the former brand, its figures witnessed a negligible decrease by approximately 8 hours, while the latter’s production time plunged steadily to 24 hours in 2002.
According to remaining two others, the year 1998 marks the dominance of General motors in production time, with 37 hours, before dramatically declining to nearly 21 hours by 2002. Conversely, Ford experienced a gradually-rising tendency, albeit with a small dip at the end. It spent 25 hours per vehicle at starting and then rose steadily, reaching just around 28 hours in the year 2002.
