Motorola developed a business management strategy termed Six Sigma to enhance the quality of process outputs in 1981. Six Sigma uses analytical methods to help recognize and eliminate the roots of errors.
Although six sigma is utilized across many industries, it’s been fundamentally adopted by Manufacturing and Financial Services. Organizations that sponsor six sigma train and certify individuals to be masters in these methods. These professionals are named Green Belts, Yellow Belts, Black Belts, and Master Black Belts.
