The provided line graph illustrates the quantity of time captured to manufacture a vehicle by four US-located cars, namely, Nissan, Dalmiar Chrysler, General Motors, and Ford over the analysed period of from 1998 to 2002
Overall, the time that consumed for assembling these four vehicles dwindled by the end of the analysed period, which was profitable case for each of them, with the Nissan and the Motors showcasing the drastic slumps and helding the predominant points, as for the DC and the Ford, both of them turned out to be in the tale, by experiencing the slightest changes.
It is remarkable that over the analysed period the time consumption saw a role reversal, with the Nissan being just under the 38 hours in 1998 and witnessing the steep shrink from 1998 onwards to 2000, reaching a point of nearly 24 hours and after experiencing the gradual slide between 2000 at nearly 24 hours and 2002 reaching just above 20 hours. Regarding to the GM which showed extraordinary point either, it saw exponential plunge of time from 1998 at 32 hours to 2002 at approximately 24 hours, notably with the lack of halt.
It should be emphasised that DC and Ford showed the marginal changes, with DC experiencing the gentle drop from 1998 at 34 hours through 1999 at just under the 32 hours variation, before remaining relatively unchanged between 1999 to 2001 at the previous level, and after showing the abrupt slump in the time from 2001 to 2002 ending at just above the 28 hours, in the tale, it is noteworthy that only one among these cars, the Ford witnessed time increasement, it experienced inconsiderable change from 1998 to 1999 being in the midst of 24 and 26 hours, before starting to climb from 1999 at nearly 26 hours to 2001 at just under 28 hours, and from then onwards declining to 2002, touching a point of just above 26 hours.
