The given line chart illustrate the fluctuation in working efficiencies of
producing a car in Ford, Honda and Toyota companies between 2000 to 2012.
Overall, while how much time it would take for Toyota and Honda companies
to make a car followed an upward trend, the figure for Ford one showed an
opposite trend from 2000 to 2004. Furthermore, the necessary working time
of Ford company then changed considerably while the remaining two companies
showed a slight change from 2004 to 2012.
It is noticeable that standing at nearly 30 days in the first year
researched, the time for making a car in Ford organization then sank to
closely 10 days in 2004 before showing an extraordinary increase to about
35 days in 2008 and constantly rising to approximately 40 days in 2012.
Besides, the time working efficiencies of manufacturing a car in Honda
company was the highest, fluctuated from 30 days and 40 days from 2000 to
before 2010. By contrast, Toyota was the slowest company in making a car
from 2000 to 2002 and between 2006 and 2012, with below 20 days.
