option a is the correct
Step-by-step explanation:
Taiichi Ohno recognized problems with mass production after working at Toyota for five years and visiting Ford's U.S. facilities.
In the 1980s, American car manufacturers adopted a Japanese business innovation called just-in-time delivery, which eliminated the need for large warehouses and improved quality control.
Just-in-time production allows car companies to outsource work to non-union plants, which affected union workers. However, just-in-time delivery also created opportunities for workers in some parts plants to interrupt the supply chain through strikes.
Ford's emphasis on cheap mass production brought benefits but also disadvantages to its workers, such as high turnover rates and repetitive work. Ford's assembly line offered greater equality compared to other opportunities of the time, as he paid White and Black workers equally.
