In 1998, the average hours to manufacture General Motor cars started at 32 hours per car, which was the least efficient in production. This was followed by a gradual fall to 24 hours before ending the period at 22 hours per vehicle. Meanwhile, this figure for Ford was slightly lower than General Motors’ time by 4 hours in 1998. After increasing gradually to approximately 31 hours, the average time spent on producing Ford automobiles witnessed a considerable decrease , and hit a record low of around 22 hours in 2005.
