Ela transcende a simples verifica\u00e7\u00e3o de regras, servindo como uma estrat\u00e9gia proativa para o controle de riscos e a otimiza\u00e7\u00e3o de custos. Ao incorporar sistematicamente considera\u00e7\u00f5es de fabrica\u00e7\u00e3o durante a fase de design, as empresas podem melhorar significativamente a qualidade do produto, reduzir o tempo de lan\u00e7amento no mercado e diminuir os custos gerais de fabrica\u00e7\u00e3o. Tornar a DFM uma parte obrigat\u00f3ria do processo de desenvolvimento de produtos representa uma mudan\u00e7a inteligente de \u201cprojetar bem\u201d para \u201cfabricar bem\u201d e \u00e9 um investimento crucial para garantir o sucesso comercial de um projeto.<\/p>\n\n\n\n
