Six Sigma is hugely popular in the manufacturing sector, though it is also used in healthcare, engineering, construction, finance, and supply chain management. Even in settings that may not completely rely on Six Sigma, there are problem-solving and quality assurance methods within Six Sigma (such as the 5 Whys) that can be helpful in virtually any setting. Much of Six Sigma involves problem-solving, which is a universal skillset. It also helps to sharpen the ability to streamline and eliminate waste in processes, saving organizations time, money, and other resources.
