 For example, the die stamping of parts from sheet steel, which the Ford company had led to new heights of development with the Model T production system, was something Henry had always been ambivalent about; it had brought success, but he felt that it was not the best choice for durability.He was determined that the Model A would rely more on drop forgings than the Model T, but his ideas to improve the DFM of forging did not prove practical.Eventually, Ford's engineers persuaded him to relent, lest the Model A's production cost force up its retail price too much.
