The line graph illustrates the specific period of the auto manufacturing by four various type of american companies over an 5-year period from 1998 to 2002.
Overall,it can be clearly observed that the while the time of car making of the Daimler Chrysler and Ford were relatively flat,it was dramatically changed in the General Motors and Nissan.Consequently,a vehicle production time were lowest in these two firms.
in 1998,Nissan had highest manufacturing time about 36 hours per car.Then,it saw a quick fall over the years and achieved 22 hours for vehicle in 2002.Despite dropping,additionally,GM showed negligible decrease from 32 hours to 26 hours in final year.
By 1998,Daimler Chrysler started at approximately 34 hours and remained steadily in the following years.After that,it had stopped at indicator such as 28.Ford which had initially the lowest fabrication timing which was roughly around 24 hours at the beginning,illustrated a moderate growth which was remained steadily throughout the period in question.Then,it had minimally dipped in the latest years and hit the index about 27 in 2002.
In summary,Nissan and General Motors developed their car making efficiency and subsequently,had the substantial results.Daimler Chrystler and Ford exhibited slight changes over the period in question.
