Professional certification demonstrates expertise in continuous improvement while showing abilities to reduce waste, leading to career development opportunities. Through certification, manufacturers develop internal leaders who execute workflow enhancements and expense reductions, resulting in improved production outcomes. The certification provides organizations with a competitive advantage because it proves their dedication to operational excellence and product quality.
