As you can see there are many areas quality control can help in any business. There are many forms of quality control and many programs all ready setup to provide businesses resources in order to proceed with implementing some form of quality control such as Six Sigma, ISO 9000, ISO 9001 and ISO 2000 and these are just a few. Some companies create their own form of quality control. But each and everyone relies on statistics to carry out these programs. Six Sigma is an overall enterprise improvement methodology that uses data to monitor, control, and improve operational performance by eliminating and preventing ‘defects’ in products and associated processes. Six Sigma emphasizes producing better, faster, and lower cost product and services than competition and stresses breakthrough improvement, for improved bottom line results. Six Sigma is also a process used to translate customer needs into a set of optimal tasks that are brought into harmony with one another.

By examining optimal process, Six Sigma can have a powerful effect on quality of products, performance of customer services and professional development of employees. The most important quality-improvement techniques stress employee motivation, change in corporate culture and employee education. Organizations known for product and service quality strongly believe that employees are key to that quality.

In doing quality control many aspects of statistics that we learned such as mean, average, expectation, variance and standard deviation would be used in order to carry out this process. Also many places use graphs in order to better visually represent data. No quality control program could exist without statistics.
