The line graph shown illustrates the standard time spent to produce vehicles by four car corporations at their US production sites over a 7-year period.
From an overall perspective, it is evident that all categories witnessed a downward trend in the given period. The most significant decline was observed in the General Motor sector.
In 1998, General Motor was the company with the highest production time in the graph, at exactly 32 hours, while the data on Ford was lower, at around 28 hours to manufacture cars. In terms of Toyota and Honda, both have the same amount of time in fabricating automobiles, at approximately 22 hours, each.
In the following years, General Motor’s motor vehicles processing time dropped slightly to about 22 hours at the end of the time frame. After reaching a peak of roughly 31 hours of producing cars, Ford saw a marginally decrease to just 21 hours in 2005. Meanwhile, the figure for Honda remained unstable during 1999 and 2002, before reducing vehicle manufacture time to 20 hours, compared to the Toyota sector with a gradual fall to 20 hours by the end of the period.
