The given line chart illustrates the length of time allocated to produce an automobile by four car companies in the US from 1998 to 2002.
Overall, different car brands followed a downward trend whereas Daimler Chrysler was the only company that did not improve its efficiency over time. By the end of the period, Nissan and General Motors had achieved the shortest production times.
The analysis will begin with Nissan and General Motors, which experienced the most significant decline. Considering Nissan, this manufacturer needed 37 hours to complete a vehicle. However, the figure dropped sharply to 30 hours in 1999 and 24 hours in 2000 and finally reached its nadir at just 21 hours. Similarly, there was a steady decline for General Motors, from 32 hours in 1998 to approximately 21 hours after 4 years.
Turning to Ford and Daimier Chrysler, Ford’s production time fell from 34 hours in 1998 to just under 32 hours in 1999 prior to stabilizing until 2001. Eventually, the production time decreased to 24 hours in 2002. In contrast, Daimier Chrysler rose marginally over the period (from 25 hours in 1998 to 27 hours in 2001) despite a slight fall to under 27 hours in 2002.
